A more experienced pilot who had studied the aux tank system may have
been able to mentally diagnose the cause of the fuel venting. But
Garmin's role in this incident is unforgivable.

I've got a few hours in a 172 with G1000, but I think that's turned me
off...at least until they get the bugs worked out.

Steam gauges don't get confused like that. While they do sometimes go
bad or give an incorrect indication, the fault is isolated to that one
gauge; it doesn't cause the entire airplane to have an apoplectic fit.
That is left to the pilot. One of the real dangers of glass is that it
usurps the pilot's perogative to panic (or not) by doing so itself.

If there's ever an argument against glass (or "advanced integrated
flight instrumentations and controls"), this is it!

NW-Pilot, would you have gone with 55 knot tailwinds?

Anything interesting in that "dialog"?

Anyway, that's quite an adventure! Would you do it again?

i posted a link at a couple of cessna "type" clubs (c.p.a. and c.p.s.).
i noticed someone did that on an earlier edition so i guessed it was ok
to do that.

someone said "a more experienced pilot would have......", well, i think
he did just great. turned around, got it back on the ground, figured it
out, flew on and made the contract. i think he needs to be
congratulated for doing something really big and doing it well. i'm
about finished reading "the flying north" and i expect any of those
guys would have bought steven a beer and listened to his story.

my airplane budget looks at getting a good harness system, fuel and
engine monitors and enough gas to do some real traveling so i don't
have to worry about a G-1000 any time soon. clearly it is a cautionary
tale about putting too many avionics eggs in one glass basket.

again, jay, thanks for being the conduit on this. great stuff.

Garmin needs to wake up! To have out-of-bounds sensor inputs reboot the
system continuously, especially something as unreliable as fuel sensors, is
horrible system design.

Even Microsoft has awakened to this. They now have fewer browser bugs per
year than Firefox.
What do you want to bet that there is a bunch of other safety critical,
software driven devices that are prone to this?

Think about this for a second. What if there was some unexpected
transmission from a GPS satellite due to an incorrect software load to the
satellite that caused the G1000 to reboot continuously. Now extend that.
Take your Garmin portable GPS out to save your butt and it ALSO includes the
deficient algorithm and continuously reboots. Scary. I would bet the
portables share quite a bit of logic and decision trees with the panel
mounts.

It's been quite an adventure for Steven. His experiences could fill a
book already, and he's only 30!

Steven, I'm curious to know what your thought processes were in that
dire situation. Stuck in IMC over the North Atlantic, in the dark, no
primary displays, a possible carbon-monoxide leak, a known fuel leak --
I simply can't imagine it getting any worse.

You did a great job keeping everything right-side up, and your head on
straight.

Why not? 55 knot headwinds cut into your fuel reserve, 55 knot tail winds
help it. I've flown with a 70 knot tail wind, it was great. Except when
I had to descend to land, then it was bumpy as hell.

At one point my GPS was showing a 210 knot ground speed, and I felt like
asking Buffalo Approach what they were showing as my ground speed, just to
brag at what a Cherokee can do. But then I remembered the story about
people doing that just as an SR-71 checked in on the frequency.

Have you ever attempted to taxi a high-wing aircraft in 55 knot winds?

On fire?

But he did a great job, notwithstanding any Monday-morning advice givers.
He evaluated, and made a decision that resulted in the craft and pilot on
the ground safely. What else is there?

He did everything by the book, but the book was wrong. A pilot is not
supposed to assume that an FAA approved book is wrong! In fact, I'm
scared of pilots who establish their own ad hoc procedures because they
think they know better than the book.

You're completely right. I'm an A&P, but I'm not going to sit up there
in IMC miles from land and try to diagnose a fuel problem if the other
option is heading for land and landing ASAP.

There's no excuse for the G1000 to reboot. I guess nobody has to test
safety-of-life systems any more.

It implies that the system was designed by desktop programmers,
instead of people with experience building mission-critical computer
systems. I guess people will have to die to get bugs fixed.

There is never any excuse for a safety-of-life computer to reboot,
short of a power interruption.

Unfortunately, there are probably a great many of them, including
anything built by Garmin.

Probably. And you can bet that nobody is verifying the generated
binaries bit by bit, the way people used to verify safety-of-life
software in the old days. If it compiles without errors, it's ready
to ship!

So you think Al Haynes and crew screwed with their DC-10 improvisation?
Personally, I think it is imperative that pilots create their own ad
hoc procedures when the book is wrong or nonexistent. I'm much more
afraid of pilots who keep doing what the book says and are afraid to
think and improvise.

Al Haynes' situation was a little different. He had multiple crew
members and a lot of backup on the ground. A single pilot doesn't
usually have the time to do troubleshooting like the United crew did.

The problem with that statement is that many GA pilots haven't even read
the book to know what it says.

Funny as that may be, Steven *was* very cognizant of how he wrote this
story up, for fear of being flamed by certain members of this group.

It shames me to think that a man brave enough to do what Steven just
did is scared of screwing up a write-up for this group. And we wonder
why aviation is a shrinking club...

Thank, You

I would feel a bit better about the system if they put manual engine
monitors and fuel qty indicators as a back up the cost to Cessna would not
be much more they have the panel space and would make the newer models safer
with manual back up instruments.

I did study the fuel system and so did the engineer that designed it and
wrote the instructions for it's usage! I would also assume so did the faa
inspector that approved the system description and usage instructions. Once
you go changing the factory fuel system design you go from the engineered
description of the now modified fuel system. They left out something very
very important in the new systems description!

I agree that continuous rebooting is a bad idea. Rebooting _once_ might
help, but the screen and/or manual should present it along the lines of:

"One of my inputs is flaky. I can ignore that input and keep going with
reduced capabilities, OR I can try rebooting to see if that clears up
the problem. There is no guarantee that rebooting will help, and there
is no guarantee that I will be able to keep going with reduced
capabilities after the reboot. What do you want to do?"

The idea of rebooting to fix an embedded safety system is not that great -
it shouldn't get into that state in the first place. But I think the
option should be there. If you want to work under the assumption that
you might get into an odd state, probably a better plan is to somehow
announce "I'm confused, but I'll keep going" and give the pilot the
option of rebooting by cycling power, rather than going into a reboot
loop on your own.

At work, I sometimes help engineering students who are trying to design
a (road) vehicle control system. If they are new to the subject, they
tend to want lots of lockouts and "clearly, this is always an illegal
condition" cases. I have had to give examples like "so, what if the
computer control of the 5-speed transmission decides it knows best and
cuts your thrust, right when all you can see in the rear-view mirror is
a huge chrome RENILTHGIERF"? The idea I try to get across is that a
large percentage of the time, the driver will have more information
about the situation than the computer will. Whether the driver acts
appropriately based on this extra information is a whole other
discussion, but at least the possiblity of doing the right thing is
there.

Sometime before early 1989, one Cal Keegan summed this up quite
succinctly: "It's not just a computer -- it's your ass."

I agree. As we've learned and re-learned many times over the years

Just as people will plead to let the NTSB give a report before you
decide what caused a crash, I think the same thing should be done here.
I'm a software engineer and I've dabbled a little in real time systems
and there are many things that can cause a system to reboot. It might
be a **** poor design or it might be something else. NW_pilot has not
given us enough data to know ( because he did not have the data either )
The biggest problem is Garmin does not issue final reports but in this
cause it may be possible to find out why. I agree that a out of range
fuel sensor should not cause a system reboot. I just went back and
re-read the story and realized that this was not truly a garmin problem.
The modified fuel system caused the problem and those additions are
outside the design envelop of the garmin system. It would appear at
first glance that the condition that caused the problem ( over pressure
in the fuel tank due to excess fuel could not happen in a standard
system and so it was not forseen in the system design) Bottom line is
that this was a modified system and to hold garmin responsible and use
that are a reason not to have advanced avionics is not good idea.

Congratulations for an exceedingly well done job. Actions speak louder

Perhaps. Here's what is on Mr. Honeck's web site at the URL he
provided at the beginning of this message thread
<http://www.alexisparkinn.com/nwpilot's_tranatlantic_flight.htm>:

[Day 2]
After switching to the aircraft fuel (from the ferry tank) strange
things started happening. The 100-gallon ferry tank went dry
after only 7 hours, burning 8 to 9 gallons per hour! Something
just did not add up...
[...]

Then, the G1000 started to go nuts, with the fuel indicators
displaying red X's. Next, I received a CO2 detector failure, then
GPS-1 failure!
[...]

When the G1000 got done rebooting, I found myself missing my
airspeed indicator and fuel gauges -- and it was now displaying a
bunch of other errors. Assessing my situation, I figured that I
had no fuel gauges, the G1000 is continually rebooting, possible
CO2 in the cabin, AND an apparent fuel leak!
[...]

As I grind closer and closer to Narsarsuaq, at about 60 miles out
they send up a rescue chopper, locate me, and guide me in, since
I am unable to make the NDB approach with the G1000 rebooting
itself. (The ADF display is tied to the G1000's HSI.)
[...]

[Day 3]
We finally figured out that the instructions for the ferry tank
were not correct, and really need to be changed before the company
installing the tank kills someone.

The problem was the ferry tank's fuel return line was over
pressurizing the aircraft tanks, causing fuel to vent overboard.
To prevent this, what needed to be done was to FIRST run the
aircraft's left tank down till it was almost empty, THEN turn on
the ferry tank.

The instructions with the ferry tank said only to "Climb to
altitude, then switch to the ferry tank and turn off the aircraft
fuel", then run it till the fuel level hits a mark on the ferry
tank's fuel level indicator. These instructions turned out to be
totally incorrect!

Even Cessna engineering was surprised that the FAA had approved
the instructions for the ferry tank setup, because it also caused
the G1000 to go nuts. Apparently the added pressure in the fuel
tanks pushed the floats in the fuel tank up, which got the Garmin
confused, causing an error that made it reboot. The loss of the
airspeed indicator was caused by fuel vapors entering the pitot
tube -- which also caused the CO2 detector failure!
[...]

[Day 11]
Then the tach started being erratic, saying that my RPMs were 4000
-- yeah, right! Then it went Red X. OK, Garmin & Cessna, you
need to have better quality control. After everything else that
has happened, this makes me not want to every own a newer model
Cessna, or anything with a G1000.

Perhaps you are correct, but It would seem that there is a lot of
corroborating evidence absent at this time.

> The modified fuel system caused the problem and those additions are
>outside the design envelop of the garmin system.

Would you care to share the information to which you refer, detailing
the "design envelope of the Garmin system?"

>It would appear at first glance that the condition that caused the problem

>system and so it was not forseen in the system design)

Typically wing tanks are filled to the brim of the filler neck.
Presumably that leaves some air trapped in the tank. Without knowing
the exact placement of the fuel vent pipe intake within the tank, it
is difficult to confirm an over pressure condition in this case.
Absent knowledge of how Mr. Rhine came to his "over pressurizing"
conclusion, it is difficult to substantiate it as fact. Might not the
venting fuel have been merely excess fuel draining from the tank as it
was designed to do when the tank is over filled? After all,
presumably it is the same fuel pump operating in both the factory
designed fuel system and the aux fuel system.

>Bottom line is that this was a modified system and to hold garmin responsible and use

Perhaps.

I thought you felt it would be more appropriate to reserve judgment
until more information was available.

Given the fact that the aux fuel system was a modification upon which
your safety depended, did you personally take the time to analyze its
intended operation from the schematic diagram and description of
system operation (not its use, but how it was engineered to operate)?
I believe you are intelligent enough to have done a reasonable job of
system analysis without benefit of specific training or an appropriate
college degree.

If I understand your story correctly, the cause of the wing tank
venting was a result of the fuel return line pouring fuel that was
being feed from the separate aux tank fuel system into the wing
tank(s). Is that correct?

> They left out something very very important in the new systems description!

Are you referring to the necessity to burn fuel from the wing tanks
before switching to the aux tank, so that there would be adequate room
in the wing tanks to hold the fuel being returned from the fuel
injection system?

Can you provide the manufacturer's name and model number for the aux
fuel system installed in the aircraft you delivered?

How large is the documentation of the aux fuel system? Is it possible
you could make a scanned copy available? In particular, I'd like to
see a schematic drawing of the system and the description of its
operation, and its operation use instructions, in that order.

I most strenuously disagree. Systems should be designed NOT to fail
catastrophically when outside their "intended use". The problem was
=not= caused by the modified fuel system, rather, the problem was caused
by unexpected sensor input. In this case the unexpected sensor input
was caused by the modified fuel system, but it could have come from any
number of reasons, and the whole point of aviation systems is that they
be robust.

The Aux system used it's own fuel pump and it was tied in after the aircraft
fuel shut off valve.

It's always poor design, unless power is cut to the system. This is
something that many software engineers don't understand.

The aircraft does not freeze in suspended animation while the system
reboots.

If the G1000 rebooted, it's a Garmin problem (although there may be
others).

Rebooting is not an appropriate response to excursions outside the
envelope.

So you're saying, that there was a new fuel selector valve placed in
the fuel line between the normal On/Off Cessna fuel selector valve and
the engine?

And the aux fuel system consisted of a fuel quantity indicator, the
aux fuel tank and vent, an additional fuel pump and electrical switch,
and a single fuel line leading from the aux fuel tank to the added
fuel selector valve?

Just FYI, NASA's Mars Spirit rover got itself into a continuous reboot
cycle too:

http://en.wikipedia.org/wiki/Spirit_rover

I've been involved in a couple of projects where we considered adding an
external hardware watchdog reboot system. (These are simple systems that
must be sent a heartbeat pulse periodically by the application, otherwise
the watchdog assumes the app died and does a hard reset of the application
system.)

Automatic reboot is of course a last resort, but given a choice between a
distant system that freezes up entirely and all hope of recovery is lost
and one that reboots into a state long enough to allow a small chance to
salvage the situation, I think the latter is preferred.

Jose[_1_]

Different application. Here we have a live pilot who can make a
decision and push the button, but the computer decides to push it for
him. There, it's completely on its own, and a last resort is
worthwhile. One just make sure the last resort doesn't get too
impatient. :)

The aux tank was connected directly to the engine after the aircraft fuel
system, Not to the wing and the provided documentation and system
description mentioned nothing about the fuel return to the main tanks. The
description also stated that it was connected after the aircraft fuel
system.

Correct, They failed to mention this the description and instruction
provided!

therir instruction basicaly short and simple! Climb to altitude on both
tanks aircraft tanks once at altitude switch to ferry tank until specified
mark on aux tank near empty then switch back to aircraft fuel.

Now!! If the instructions stated to run on the left tank till near empty
then switch to the ferry tank and monitor the left tank fuel quantity and
return to aircraft fuel and switch ferry tank off when left tank was almost
full about 2 hours flight time this little problem would not have happened.
The Greenland CAA took a copy of the instructions and fuel system
description and copy of Cessna description of the problem and will be
contacting the ferry tank mfg and installer telling them to correct their
system instructions.

The Ferry tank was Manufactured And Installed By Telford Aviation In Bangor,
Maine. In the future I will try and avoid this company or flying with this
company's installed equipment if at all possible and if I am to use them
(Not Likely) I will require them to provide a full schematic of the system
and talk with them more to support their documentation. Another thing that
****es me off when I called the company (telford) to help with the problem
they were rude and said there instruction were correct and that it was not
their problem! Cessna support and the weekend A&P in Greenland were the best
they had a solution with in a few hours after faxing the instructions to
them and are also writing a letter to Telford explaining the problem with
their instructions.

No schematic was available only textual description of the fuel system and
its operation. All paperwork was given to new owner and there was no photo
copy machine available in Beirut at time of delivery for me to make a copy
for myself. The Greenland CAA made copies of all paperwork and said they
will forward me copies of all paperwork.

Don't think it was just one error causing the system to fail and reboot I
think it was multiple problems compounded by 1 problem. But still the system
should not reboot itself. When on the phone with Cessna engineering and
Garmin support they said they had a similar problem during stalls and slow
flight.

The 172 SP has a fuel slector Valve L - B - R Plus A Fuel shut off Valve!

The Ferry Tank had a shut off valve fuel pump a hose that connected after
the aircraft fuel system shut off valve.

See Photo! Look by the aircraft fuel Selector You will see a Fuel Shut Off
Valve and The Fuel Pump with Switch.

How would the fuel get to the main tanks in the first place? Is the
engine the only connection? (if so, with the fuel selector OFF that
should block fuel flow to the main tanks). Is there a vent line that
connects them?

We don't see much in the way of that sort of "creative writing" in

If the lurkers post USEFUL INFORMATION, that is correct and supported

Welcoming EVERYONE? You feel critical thinking* is misplaced? You

Kaczynski, Ted Bundy, John W. Hinckley, Jr, ...? Welcoming EVERYONE
could reduce Usenet to a the status of FidoNet. If you don't mean
'everyone,' don't use absolute language.

I have no tacit agenda to entice the timid to indulge in aviation.
If they are afraid of public response to their words, they are
probably much too fearful to become airmen.

Although you apparently believe Usenet was intended for kibitzing,
inane prattle, and chit chat, it is actually for the sharing of
INFORMATION.

This fellow put it well:

In my opinion, it is a very helpful (and in some instances quite
necessary) virtue to be able to take criticism even if it is
offensive or insulting. In fact, even the most offensive
criticism might (and hopefully does!) contain insights that are
valuable, and by disregarding the entire criticism, you are
throwing away that insight. You may not like it, but it sometimes
does pay to listen to a person that is not as friendly as you'd
like her to be.

So, the uncommanded FIS rebooting was a known issue, and both
manufactures chose to release their products for use? One would have
thought Cessna would have learned not to do that from their seat-rail
issue. I hope the premiums are paid current on their errors and
omissions insurance policies.

Read Mr. Rhine's narrative. The FI system has a fuel return line to
return unused fuel pumped to the engine back to the wing tank(s).

Is this dumb, or is there a good reason not to return fuel to the tank
whence it came, in this case, the ferry tank?

Larry,

Andrey Serbinenko
October 2nd 06, 08:26 PM
A few years ago, I remember reading an excellent book on general design of
modern avionics. In particular, one thing that I believe is different between
Garmin's baby and what they have in B-s and A-s is redundancy. The whole thing
there is doubled, and some critical components are tripled. And then there's
a whole body of software that takes care of voting-elimination among inputs.
By design, the event of the computer reboot (i.e. all three redundant computers
reboot) is perhaps as likely as the event of all four engines quitting at the
same time. What surprises me is that Garmin got FAA approval for such a system,
whereas it doesn't even come close to what "normal" glass cockpit is supposed
to be like in terms of robustness of system design. I understand it's all done
in the name of affordability, but this is clearly a dangerous game to play.

If you think about it, just to be able to claim any kind of "robustness",
you should be reasonably sure that there's no single failure that will take
the whole system out, right? And there we go: excessive fuel venting took
airspeed indicator out completely, and CO indication out completely. And this
is aside from any software bugs; this is the way G1000 is supposed to work
by design!

So, I guess my point is: you can't just take a steam-gauge-type airplane,
replace all the individual *independent* instrument systems with one
electronic box, and claim you've got an equally reliable plane. No way. By
tying everything together and establishing inter-system dependencies that
never existed before, you increase your likelihood of a catastrophic failure
by orders of magnitude. If you want to use an all-in-one instrument system,
you need to redesign the airplane and fit it with redundant systems to
compensate for that loss of overall reliability.

That's the book, btw:

Excess fuel from the engine is returned to the main tanks. Twin Cessna's
are the same way; if you switch to the aux tanks before burning a certain
amount out of the mains (90 minutes for the large aux tanks) the mains will
overfill and vent overboard before the aux tanks are empty.

There would probably be a significant amount of under the cowling work that

Yea, its a scary thought! The G1,000 System is nice when it works "Great IFR
platform for situational awareness" But they do need some manual back up of
some critical items for safe IFR flight. I know I would not fly into IFR
conditions in a G1000 equipped airplane with my family or a passenger on
board. After sitting for 70 hours on Cessna version of the G1000 Scares the
hell out of me and it takes a lot to scare me! To many bugs and failure in
70 hours of flight! Look at my finial day the Tach. even failed!

And there is a note in the description of that fuel system that explains
that! Which was not included in the description of the modified fuel system

Not that I want to excuse those system failures the least bit, and not
that I would not have an adrenaline rush in that situation, but there
*are* manual back ups for the critical items! At least in those planes
I've seen so far, there has always been a "steam" AI, a "steam" ASI, a
"steam" altimeter and a whisky compass. You can perfectly fly in IMC
with this equipment.

> Look at my finial day the Tach. even failed!

Hardly a critical item.

That is true, I am not inferring anything. You would think the tank company
would be familiar enough with the aircraft they are installing tanks into to
have a working (correct) procedure manual. Surely you are not the first to
ferry this particular combination.

The G1000 system If you buy one or intend to fly one in the Soup be current
and really proficient on you partial panel skill because in the event of a
G1000 failure or even partial failure you will be left with and Compass,
Altimeter, Attitude Indicator, and Airspeed Indicator and a bunch of useless
knobs and buttons or questionable reading from a partial failure. It's
almost an IFR pilots worst nightmare yea a Vacuum and Electrical System
Failure as when the G1000 goes radios, navigation, & transponder go along
with it!

I don't think it would cost Cessna much $$$ to put some manual back up
instruments in the panel even if they are the small ones they already charge
to much for a skyhawk why not add 3k or 4k if even that much to the price
and add some redundancy to the system!

I think it's short-sighted, as it didn't consider the entire fuel system.
From the description that NW_Pilot gave, the aux fuel system seems more
like a kludge than something that was designed.

Are you saying that Cessna designed the fuel system that way, and the
FAA certified it? Or are you referring to a ferry tank?

It makes you wonder if the FAA would certify kinking the fuel line
instead of providing a valve to shut off fuel flow. :-)

Was that a mechanical tach?

I would write a report of your experience detailing the equipment
failures that occurred, and politely and respectfully send copies to
Cessna and Garmin. If you word it, so that it contains implicit
references to their exposure to civil liability, and express your
disappointment with the performance of their products, who knows how
they may respond. They may try to appease you with a perk or two. If
not, forward the report to AOPA, FSDO, and AvWeb. :-)

I would not say perfectly you can hold straight and level and do climbs and
descents but without a reliable source of navigation except for a compass
(which has it's errors) and the deviations in Greenland area can be as much
as 40 degrees then add the wind correction makes for challenging navigation
for a few hundred miles with only a compass. Now when the only approach you
have is an NDB and the indicator don't work hahahaha!!! Trust me you don't
want to be there it's not fun but, it is a rush up until the moment you turn
on your portable gps and it downloads your present position and draws a line
to the nearest airport 200+ miles away!

On the contrary. When flying an aircraft that has just had major
modifications to critical componets and/or systems, one becomes a test
pilot. There is nothing wrong with this - SOMEONE has to be a test
pilot.

However, there is a difference between flying proven production
aircraft and being a test pilot. The pilot flying proven production
aircraft need only study the approved guidance and procedures (the
book!) and fly by the book - and usually all will be well. This is not
because the
book is FAA approved, but because it is time-tested. The FAA approval
is pretty much irrelevant.

When one becomes a test pilot, the world changes. Now the pilot must
study the system in detail (pulling off the cowls and tracing the lines
if necessary) and understand exactly how it works. He must consider
the normal operation and the failure modes. This will give him an edge
in troubleshooting if something should go wrong in flight, but that is
secondary. More importantly, it makes things going wrong in flight far
less likely.

Reading the book and flying by the book is not enough in this
situation. The fact that the book and the system are FAA-approved is
irrelevant. Neither the book nor the system are time-proven. Unless
you are prepared to trust a bunch of federal bureaucrats who couldn't
find better work with your life, you need to understand what it is they
approved.

> In fact, I'm
> scared of pilots who establish their own ad hoc procedures because they
> think they know better than the book.

Being a test pilot is often all about coming up with an ad-hoc
procedure, because the book is wrong - because someone didn't think of
something.

Now for our adventurer:

Once the emergency developed, you did a good job flying the emergency.
I don't want to take anything away from you there.

Your preparation for the flight, though, was incomplete. You knew that
you had a highly modified fuel system which is rarely installed on this
sort of airplane. You also knew that you had an injected engine. The
FIRST question you should have asked is - is there a vapor return line
(not all fuel injected engines have them) and if there is, where does
it go? I'm guessing you didn't ask the question because you didn't
have experience with other airplanes where this was an issue. That's
the value of breadth of experience when it comes to being a test pilot.

I accept that your documentation did not answer that question. But the
problem is, you didn't even ask it. Had you asked, you could have
gotten some sort of answer - and in any case, even a cursory
examination of the plumbing would have told you that it wasn't going
back to the ferry tank (they never do, you know) and would have forced
you to consider the problem - and to develop an operating procedure a
lot more correct than the approved one.

In theory I suppose it could be possible to become a capable,
proficient, experienced pilot without making mistakes like this and
scaring yourself. I've never seen it happen. Every experienced,
capable, proficient pilot I know got there the same way - by going out
and doing stuff, amking mistakes, and scaring himself. The difference
between the ones who get there and the ones who drop out along the way
is basically this - the ones who get there learn from the experience,
and learn not to make the same class of mistake again. You see, while
you handled the emergency, that's not the sort of thing you can count
on handling 100 times out of 100.

I'm sure you won't make the exact same mistake again - not
understanding what your modified fuel system really does - but the
lesson to learn is broader. If you are flying something that has been
modified from the norm, make sure you understand the full extent of the
modifications and their implications before you launch.

Larry, That's a great Idea and the Tach. was part of the G1000 system I am

I trust you. All I said is that there are all the backup instrument
needed to keep the plane flying. Now if your mission *relies* on
electronic navigation aids, then it's a good idea to have such a backup
handy. But not all missions rely on them, so I don't see the need to add
them by default.

Seriously, you need to develop a method of filtering language so you

"Adolph Hitler" or "Sadaam Hussein", or "Bill Clinton" -- but it DOES
mean guys like NW_Pilot, who is CLEARLY not a timid soul.

Ironically -- sadly -- they sent the messages to me off-group, for fear
of the reaction they might generate by posting.

Most software licenses disclaim all responsibility for everything
except an unreadable CD, although these disclaimers have never been
thoroughly tested in court, as far as I know.

Oh! Yea I learned a bunch from this trip.... I did ask questions about the
fuel system prior to launch "I have flown other tanked airplanes" and the
answer from them was the same that was written on paper when the aircraft
fuel system is completely disconnected "In the off position" the aircraft is
running only on the ferry tank system connected directly to the engine after
the aircraft fuel shut off valve.

The chances of myself refering or using this company for tanking is slim I
did not pick this company the customer did and the customer was not happy
with their services anyway they did a **** poor job at cutting the panel
when they installed the ADF and PS eng. entertainment system. (I could have
done a better job with a hack saw and a drill) and the painting on the
Horton kit they installed looked like orange peal!

I myself prefer the turtlepac bag systems (Used Them A Few Times) they are
set up to transfer fuel form a fuel bag to a main aircraft tank they are
really simple and work great! http://www.turtlepac.com/collapsibleair.htm

My guess is that the FAA doesn't know how to certify glass cockpits.
There are no procedures in place to certify software, or for some
reason they are not applied to toys like the G1000.

Is a G1000 cheaper than a set of normal instruments in the cockpit?

Not rare or improbable at all!!! Stalls and slow flight are used during

As long as the aux fuel line was ahead of the fuel
filter/gascolator(?), or the aux fuel system contained its own filter,
that is the logical point to feed aux fuel to the engine. Without a
check valve between the Cessna fuel shutoff valve and the point
between it and the engine where the aux fuel line was attached, there
is also the possibility of back feeding fuel into the wing tanks if
the Cessna shutoff valve is left open while the aux tank fuel pump is
in operation. Did the instructions mention such a check valve or
closing the Cessna shutoff valve?

Do you know the name of the individual who wrote that? Do you know
the name of the FSDO inspector who certified the aux fuel tank
installation? I would contact those people personally, and make them
aware of the hazard they caused.

Given the inoperative fuel gages, the wing tanks could have filled up
at any time without your being aware of it. Considering your mission
and the operation of the aux fuel system, fuel gages are critical to
an Atlantic crossing. Cessna, FSDO, and Telford should be made aware
of that fact.

It would be good for you to have a copy.

You have made the crossing before, right? Who manufactured and
installed the ferry tank(s) you used on previous Atlantic crossing(s)?

Yes, the aircraft fuel was shut off by closing the aircraft fuel valve.

Good luck with that. I'm thin skinned, but at least I know how to use a

Welcome home.. glad it worked out safely...

and without sounding high and mighty.. I'm guessing you will pay greater
attention to the fuel system and its architecture in the future...
particularly when aux tanks and injection return lines are involved.

Also.. do everyone else a favor and file a NASA form.. not because of
alleged rule breaking, but because you have discovered a true safety of
flight issue that needs to be addressed.. the sooner the better.. Garmin
needs to have a fault exclusion algorhythm that removes nonsensical
readings from it's decision tree.. rather than causing a software crash..

To the contrary.. ferry tanks are are NOT UNCOMMON and this is a
foreseable modification. This is something that should have been
contemplated.. if not by the manufacturer then by the ferry tank
installer/STC holder.

Bottom line is.. a faulty fuel gauge for whatever reason should never
ever cause your whole damn flight instrumentation and display to crash
and reboot. This is a simple, fundamental idea

Oh! Now that was a rude analogy! :-) :-) (LOL)

Say what you will about the pedantic Mr. McNicoll, but the vast
majority of his comments are accurate and succinct, and contain useful
INFORMATION. He uses his full name, knows how to punctuate and
capitalize, and lends an air of dignity befitting an airman. Those
unenlightened, ignorant, two-digit IQ, illiterate, wannabes who dilute
the content of this newsgroup with banal attempts at crass humor and
insipid, empty headed comments reflect badly on airmen in this
worldwide forum. I'll take one McNicoll to a dozen of the latter.

>Seriously, you need to develop a method of filtering language so you
>can detect mild hyperbole. In this case "Everyone" doesn't mean
>"Adolph Hitler" or "Sadaam Hussein", or "Bill Clinton"

You're have the arrogance to fault me for your improper use of the
language?! You can attempt to redefine the meaning of the word
'everyone' all you like, but I doubt you'll be successful at making it
mean other than: every person; everybody. If English were your second
language, I would not be so critical of your casual use of it.

Say what you mean, and mean what you say. It is not incumbent upon me
to have to divine your meaning. You are capable expressing your
thoughts explicitly (aren't you?).

It's difficult enough in written communications to correctly infer the
writer's meaning without the benefit of observing body language. And
last thing I want to be guilty of is reading something into a person's
prose that they didn't intend.

>-- but it DOES mean guys like NW_Pilot, who is CLEARLY not a timid soul.

Mr. Rhine posted something that was dumb and illegal when he first
began to de-lurk. He met swift and significant criticism. His
feelings were hurt, and he threatened to quit rec.aviation.piloting.
But after the psychic pain of the initial lashing wore off, and he was
able to reflect on that responses he received, he gained a new respect
for the fellowship of airmen and himself, and he has ceased to be a
black eye for the public image of airmen. I would guess that he would
rather be criticized than have to wade through hundreds of banalities.

Well here's a message thread they can use to express their views.

Those who are so fearful of public ridicule as to refrain from
participating in this newsgroup probably do so because they have
nothing, other than chit chat and banalities, to contribute. If not,
let's see them post some relevant INFORMATION or personal experiences.
If they can't stand critique, they should probably stick to other
forums like rec.aviation.misc where they can wallow in the mud with
others of their ilk.

Your noble attempt to champion the timid reflects your view of what
Usenet should be: a place to kibitz with friends. Although many
newsgroups have degenerated to that level, thankfully this one hasn't
yet. That's what makes it attractive and useful. When it becomes a
bunch of grandmas chatting over the back fence, you will not see me
posting any longer.

I wish you had seen Usenet before AOL. Talk about intimidation; the
conversation was so witty and erudite, that no one ventured a post
without meaty content and careful attention to detail.

Please, let's not welcome those comments that would cause the lay
public think we airmen are a bunch of vulgar simpletons and
Philistines who lack critical thinking skills.

Obviously we are at opposite ends of the spectrum on this issue. I
have history on my side.

I should have said the "tip tank" Twin Cessnas. Cessna designed it that
way. Fuel injected cars do the same thing but have only one tank to return
the fuel to so it is not a problem. If you wanted to return the excess fuel
to the same tank it was drawn from you would need two sets of directional
valves; one on the supply line and another on the return line that were
synched to each other. It is much easier just to tell the pilot to burn 90
minutes out of the mains before switching to the aux's.

congrats on a successful flight NW... half of me is really jealous and
the other half thinks it'd be too scared to try that even if given the
chance. loved the story though...

i was curious about cessna's explanation of the airspeed problems - you
said "the loss of the airspeed indicator was caused by fuel vapors
entering the pitot tube". how did it get in there? the wing vent is
well behind the pitot, right? i see the picture with fuel on the
nosewheel, did that come ouf of one of the drains under the fuselage?
did you lose both the G1000 and steam gauge indications or did one keep
working (accurately?)

thanks,

todd.

What you fail to see is that your harsh criticism of anything you find
less than worthy is keeping many educated, experienced airmen from
posting. Your verbal barbs, meant to be smart bombs, are actually
closer to carpet bombing in their effect. And the resulting collateral
damage is killing our allies as well as the enemy.

> Please, let's not welcome those comments that would cause the lay

First you do everything you can to keep people -- especially the lay
public -- from posting here. In the next breath you're worried about
what they might think of us?

> Obviously we are at opposite ends of the spectrum on this issue. I
> have history on my side.

I, unlike you, enjoy posts of all sorts in this group, but (in case you
haven't noticed) the posting group has recently shrunk to historically
low numbers. There seems to be about 20 regular posters left here,
which is down considerably from past years. I attribute this to a
number of things, but one major reason is the harsh slap-downs that
many new posters have received when they stuck their toe in the
rec.aviation waters...

What would prevent plumbing the fuel return line into the top of all
fuel tanks above the fuel level, so that the returning fuel would be
able to fill whatever tank space was available at the time? There
would be the added cost of labor and materials, and the added weight,
but the hidden hazard would be eliminated.

I flew a long trip in a Bonanza in 55 knot tail winds (it cut out one
refuelling stop, too). The SURFACE winds were under 15 knots. The wind
at 9000 feet can be much stronger than at near sea level.

Ever since Steven Ames got flamed to a charbroiled crisp over a loose
formation flight (with a CFI as the wing man), I've always had to resist
the temptation to post about the flight of four we did consisting of a
Cessna 140, Cessna 170, Grumman Tiger and Beech Bonanza. So far I've
resisted because I think I'd be trolling if I did that :-)

But a fuel sensor out of range SHOULD NOT CAUSE THE SYSTEM TO BOOT LOOP.
Why should a fuel sensor out of range deprive you of your EHSI and
attitude indicator? The read outs for the instruments out of range
should be flagged and a suitable warning message generated - not the
loss of your entire IFR panel.

John,
I work in Real Time systems on packaging equipment. It's certainly not
life-or-death equipment as is the control panel of an airplane, but I can
tell you unequivocably that a robust system will not reboot just because a
sensor behaves inconsistently with specification. Sensors fail all the
time. They even fail "high".

The description of the incident demonstrates evidence that not only is the
G1000 not robust, but it also ties many or all of the subsystems together
where a single sensor failure leads to catastrophic results. After all,
sensors can fail even if they are not attached to long range tanks.

Had the Fuel System display simply shown red X's and shut down because of
the invalid input, I would have said that to be acceptable (although not
ideal). The pilot would have immediately recognized a problem with the fuel
system, recognized that the red Xs were not consistent with a total
instantaneous loss of fuel, and known where to look to diagnose the
problem. But he would still have his GPS, and other instruments, and been
able to easily navigate to the nearest safe point to diagnose the problem
on the ground. Perhaps he would have even initiated a reboot or two on his
own.

However, in this case, the fuel sensor failure caused a total system
failure, including misleading readings such as CO in the cabin, lost
airspeed and lost GPS. The bad fuel sensor reading not only "bricked" the
system, but from the description, it caused the system to put forth false
information about the cause of the failure, making diagnosis extremely
difficult even after the fact.

That certainly brings to light some very interesting questions about the
safety of the G1000 system. I wouldn't want to put my life into the hands
of a system that bricks when a single sensor fails.

Most software licenses are not certified by the FAA.

Software that is certified by a regulatory organization typically is held to
a bit of a higher standard than the desktop software pushed out by Microsoft.

Another good example is FDA certified software in the Pharmacuetical
industry. They too have a CFR much like aviation does, and have rigorous
standards for testing and certification before any change can be made.

Neither did NW_Pilot... Piloting is quite a bit more than software and
steering.

True. In addition to the fuel sensor "overload" (it didn't really fail
-- it just sent info to the G1000 that made no sense), he also
experienced a CO sensor failure, and (later) a tach failure.

It's hard to say what caused what to happen, without more data.

Sure, you can keep the plane aloft, but how would you navigate or fly an
approach? By the compass and Dead Reckoning? I guess it's not that much
different than an alternator / battery failure. But I think a total
electrical system failure is pretty rare. And while often missed, there are
warning signs that can give you advance warning of an impending electrical
failure so that you can get to safety (VFR or on the ground) before you are
left without effective navigation instruments (VOR, GPS, etc.). You can
even control the amount of time you have by reducing consumption (ie:
turning stuff off) and saving it for the necessary phases of your flight.

Sensors fail frequently by comparison. Hell - fuel system sensors fail so
frequently that every pilot I know checks his fuel level visually because
the fuel sensors can't be trusted. There are even discussions about whether
a fuel sensor that reads empty all the time is legally considered failed!

There is built-in redundancy in the airplane electrical system - you have
an alternator and a battery. Having your redundant electrical system
essentially undermined by a poorly designed glass panel that fails
completely when any one sensor misbehaves is unfortunate at best, and is
added risk that seems unjustifiable.

Fair enough...

Anyone with a G1000 want to test the theory out?

Your right it should not cause the system to reboot but the question is
who fault was it? Was it the sensor that exceeded it's valid output
values do to a improper installation of non standard equipment? Where
in the garmin code did it blow up? I can imagine that the fuel level
value is used in many places in the code. Was it a minor sub-system
that got modified and had a dependencies creep in that was not foreseen?
To try and test a integrated device like the G1000 with all the inputs
out of valid range is a non-trivial test and it would not surprise me to
find out in the end that this whole mess was caused by a modification to
a subsystem that used the fuel value that was not part of the system
when ( and If ) the testing was done with all the values out of range.
What operating system does the G1000 use? Does it use a OS that
seperates the various processes that control functions or is it a single
large program that can reboot if a process goes into a unrecoverable
error. I don't know the answers to these questions but I'm willing to
bet that there are a number of engineers at Garmin trying to figure out
what the hell went wrong here.


To clarify my earlier post: Go ahead and blame Garmin ( which may or
may not be right ) but don't use this failure as a reason not to have
advanced avionics in aircraft.

I agree that we are in no position to determine the cause of the problems;
they could be specific to this particular unit, or caused by damage during
the installation of the ferry tank and other panel mounted items rather
than the general design of the G1000. However, it still troubles me that
Garmin told NW_Pilot that the system can experience similar problems
during stalls and in slow flight. That *does* sound like the G1000 has
some design issues that need sorting out.

First, you'll have to provide a few examples of what you find
objectionable about what it is I said before I will accept your "harsh
criticism" assertion.

Further, you make me laugh when you assert that I have the power to
prevent "many educated, experienced airmen" from participating in the
newsgroup. That is absurd on face. I'm afraid I'm completely
unworthy of the power with which you endow me, as are we all. Usenet
has always been open to all who choose to avail themselves of
participation.

And, beyond that, why isn't it the vulgar and insipid posts that
prevent folks from wanting to be counted among the
rec.aviation.piloting readership?

What are you suggesting exactly, that all us who you deem "harsh
critics" silence ourselves or self-censor our comments to suit the
silent ones? Are you able to be explicit about exactly what it is you
want?

Again, without examples of what you characterize as "verbal barbs,"

Oh please! I was raised in a family that enjoyed long and sometimes
heated political debates whenever they got together. Pilots are often
a rather direct and terse in their conversation, but that is not a bad
thing in my opinion; it's just different.

The way I see it, if civility is maintained, and denigration, libel,
and profanity are avoided, there is no valid reason for complaint.
Some folks see argument, debate, and discussion as hostile, but you've
got to admit they are the domain of Congress and thinking people
everywhere. So if that's what frightens the "many educated,
experienced airmen" you champion, I'm unswayed.

Now that is a completely unfounded accusation. Perhaps you'll see

I'm not worried about anything. I just prefer not to see our fellow
airmen publicly embarrass themselves and reflect badly on us all
generally in an archived, worldwide forum. I'm sure you appreciate
the fact that the articles we post to Usenet are not ephemeral.

So now you're implying, that my articles are not only prohibiting
"many educated, experienced airmen from posting," but they are
reducing the number of regular contributors? Ridiculous.

>I attribute this to a number of things, but one major reason is the
>harsh slap-downs that many new posters have received when they stuck

Well, you are certainly free to reach any conclusions you please. But
I haven't seen anyone leave for that reason. Perhaps you'll be good
enough to provide reference to some articles that support your
unfounded notion.

There are certainly other reasons folks cease to participate in
Usenet. But regardless of how you see it, you've got to admit there
is a wealth of information posted in this newsgroup and a lot of
experienced pilots and mechanics who generously share their knowledge
here.

Take my fellow Californian, Mr. Weir. He is often less than cordial,
but he is also often a fountain of information. Or Mr. Duniho's often
deliberately abrasive manner. People like these are the true
educated, experienced airmen you should be thankful for. Are you
suggesting that they change their demeanor too, or just me?

So tell your fawning "educated, experienced airmen" to quit wining,
and join in the discussion. Who knows, their fragile psyches may
toughen up, and they may grow a little, but they will surely benefit
from the experience, as you have.

I just went back and reread his account. ( I'm not flaming Steven but
if you've read his emails before you know that his written words can
often be difficult to read for content ) He said that the fuel readings
went to red Xs ( as a properly designed system with a out of spec sensor
should ) after flying ( and venting excess fuel for 7 hours ) Then he
got a CO2 warning then a GPS-1 failure. It was after the GPS1 failure
that the unit rebooted. Now failure of the fuel system I would not want
a reboot for but in some situations failure of the primary navigation
system may be grounds for a reboot depending on what failed. After the
reboot completed he was missing readings like fuel and airspeeds. He
mentions other errors but does not say what they were. He does not
specifically say that the system rebooted again directly. He said in
summery it was continually rebooting but I question that. Steven - Was
it rebooting or did it just reboot once after the initial failure? He
mentions that on downwind the fuel readings were working again but then
failed again during turn to final. Did the sensors starting given valid
information after the fuel burned off enough to have then in range and
then fail again during the turn? Not sure. He does mention the G1000
rebooting again during his landing. Was this the second reboot? Did
other instruments fail again? Too many questions and not enough
information to say for sure.

You'd be surprised. There's a lot more to the wind speed difference

Be that as it may, I'd be reluctant to taxi a C-172 in anything

In any plane the weight of a C172, you should exercise caution when
taxiing in winds of 20 knots or more. I routinely used to fly a C172 in
those kinds of winds (or otherwise I wouldn't have got to fly very
often). Proper positioning of the controls is highly recommended. I've
flown lighter taildraggers in stronger winds than that - it's not
something for a novice, but with a modicum of experience and care it can
be done quite safely.

Those are prices of the aircraft with the option package. So the Skyhawk
with the Nav III package is $241.000. Or, so you can understand the figure,
every cent you earn for the next 30+ years.

I don't know about that. An inability to build proper reliability into a
system would sound to me like a good reason to avoid it.

More, I've been thinking about the statement "it rebooted". There really
shouldn't be an "it" in an airplane, should there? There should be a
"they", right? And the statement should have been "one of them rebooted".

There are two screens for redundancy, but only one system?

With respect to the sensor providing bad data: sensors can provide bad
data. They break. Part of the job of the unit accepting input from the
sensor is to flag such failures. This isn't an "odd case"; it should be
one of the tasked requirements.

All that said, I'm uncomfortable with some of the symptoms described. Why
would the AHRS have a problem because of a bad fuel sensor? How would
fuel contaminate a pitot tube (in my 182s, they're not positioned such
that this could occur)?

My first thought is that there's some problem particular to this unit that
was being flown. Failing that, I wonder what else in the environment
might have triggered the multiple failures.

Will solve this question, It had to many reboots to count! The unit would
reboot then start showing items failing then reboot again start showing
items failing then reboot again and again for a few hundred miles! After
each reboot it took about 10 to 15 min to reboot again. The fuel sensors
starting given valid information upon the reboot after landing and I still
had Co2 and GPS Failure On Landing and airspeed was still a Red X! I only
took note of the critical errors I tried my best to document them all but I
am not superman I still needed to fly the plane.

First of all, I think you did a superb job of handling all aspects of this
fiasco. It has to be awfully distracting to have your controls constantly
rebooting while you're trying determine whether you can get to safety.

Your description of the installation quality of the aux tank and other
items in the panel that could have been done better with a hacksaw and a
drill makes me suspect that the G1000 was damaged during this process. The
only thing that makes me think that the G1000 design may have problems is
their telling you that the unit experiences problems in normal flight
configurations. I'm curious about *which* problems, but that's only a
curiosity; I'd have a hard time trusting the unit if there aren't backup
gauges.

If I were flying the kind of flying you are doing I'd invest in a 496. It
would give you at lease some level of backup for almost everything in the
plane except radio and engine instruments.

I agree. I wonder if it was just the fuel sensor that caused the

The 172 I flew with the G1000, it was linked.

Besides, after that avionics failure, I'm not sure I'd trust anything else.

and as had been pointed out by a number of people, there is no solid
evidence that make it clear that the reboots where caused by the out of
range sensor. Even the original story said the fuel displayed displayed
red x before other system failed and eventually rebooted the overall
system. Even it the G1000 is a bad design/system, it's still no reason
to say that we must stay with steam gauges.

Yes, it was coupled to the G1000 and was useless!

No, it is not.

It would however mean that the G1000 is a bad design/system.

More to the point, it is an =attractive= bad design/system. That's the
nub. Glass is really sexy, and because of this, can be marketed =even=
if it's a bad design/system. One should be suspicious of glass =for=

I believe that there are many reasons for redundancy and the potential
for a poorly designed system is one of them.

Odd considering the fact that a software failure is far more likely
than a screen failure. But putting in an extra screen is a lot
cheaper and easier than debugging the code, and it _looks_ safer, too.

It doesn't matter what caused the reboots, because only defective
software reboots in the first place.

True. But a truly safe software system would be so expensive that
nobody could afford it--which means in effect that we should stay with
real instruments for the time being.

Most people designing and writing software today have absolutely no
clue when it comes to safety-of-life issues. What worries me is that
systems like this are being "certified." Apparently certification
means very little when it comes to software.

Yes. Still cheaper than a Baron 58, the aircraft I like, which
apparently sells for just over a million dollars now. It's a rich

I read the other day that a new Baron is selling for (I think) $1.7
million now.

Personally, I think you'd have to be dumber than a box of rocks to pay
that much for a Baron -- hell, you can get a nice biz-jet for less --
but there were apparently 17 people in 2005 that possessed the unique
dual-qualities of "dumb enough to do it, and rich enough to afford

I don't doubt it. But did you ask the right question? I don't think
so.

So what makes that question the right question, other than hindsight?
Well, as someone else mentioned, there are actually production
airplanes (the C-310 comes to mind immediately) where this is an issue.

This answer is clearly inadequate. It does not tell you where the
vapor return line goes.

Note that this identical system with the identical instructions would
have been totally fine on a plane with a carbureted engine, or with a
small Lycoming injected engine equipped with the Bendix/RSA fuel servo
(and this covers the vast majority of 172's - I'm curious what flavor
this one was) so it is entirely possible that the system has been used
successfully in many 172 crossings.

The sytem itself is fine, especially for something like a ferry flight
- the only problem is that someone dorked up the instructions. These
things happen. That's why you're being paid to do this.

Yes....but, He has to get training and a check flight in that

in a Cessna 172 every two years. I've done Flight Reviews for
a couple of guys who traded in their biz-jets for high performance

If a pilot sits into an approved airplane, reads the approved
instructions and acts as instructed, then I think I this pilots has all
the right to assume that the installation works as expected. That's why
such installations are so expensive.

Good point -- but my comment was more aimed at the price of a new Baron
than at the quality of the pilots. I mean, my God -- $1.7 MILLION for
a piston twin? Given what that would buy on the slightly-used
market, it's just insane to give Raytheon that much money...

The possibility of loosing all navigation, engine, and systems
information and autopilot simultaneously while single-pilot IFR over
the Atlantic Ocean between Greenland and Iceland is not an acceptable
risk in my estimation.

Even the auto pilot became inoperative, because it is dependent on the
Garmin equipment, so the pilot was forced to fly partial panel
(airspeed, AI, altimeter, and compass)for 200 miles back to land.
Here's a photo of the Cessna panel:
http://skyhawksp.cessna.com/avionics.chtml
He lost fuel gages critical for decision making about whether to
continue on or turn back.

The Garmin product should be redesigned in a modular way, so that
failed modules can be isolated, and permit the operational part of the
system to function. And the modules should be designed, so that they
are able to provide functionality, even if it is reduced, when other
modules are inoperative. There will always be some single points of
failure, like the display or power supply, but the likelihood of
catastrophic system failure would be reduced. To compromise safety
for the sake of gee-wizz glass is just plane stupid.

The systems Garmin replaced were specifically designed to provide
redundancy and several isolated power sources, so that the probability
of such a catastrophic failure was unlikely. A rational pilot would
not knowingly sacrifice that redundant and independent system design,
no matter how cool a glass cockpit is.

Consider what is between you and an approaching automobile on the
highway, a white stripe, and consider what is between you and such a
catastrophic lose at a most inopportune time, a few microns of
silicon. Would cosmic particles affect electronic equipment near the
Earth's poles?

Is that a typical price range for a plane in the Baron's category? If
not, why is the Baron special?

And if you believe that, there's a bridge I'd like to sell you.

Seriously, what you say makes sense in theory. The difference between
theory and practice is often much greater in practice than it is in
theory. In theory, the installations are expensive because thorough
and competent engineering review (by the DER) assures that version 1.0
works properly. In practice, becoming a DER has little to do with
thoroughness and competence and everything to do with having
connections in the FAA.

Anyone who has worked on the maintenance side of GA for any length of
time has his own share of stories about totally incompetent
modifications that gained FAA approval. This one is small potatoes in
comparison with some of the ones I know.

Thus you have to accept that if you are flying version 1.0 of anything,
you are a test pilot and must behave accordingly. There is a very
expensive mandatory process in place to assure that this does not
happen, but the process doesn't work.

Why?

The Garmin audio panel in our planes has a nifty feature. If the panel is
powered down, the pilot's headset is connected to COM1. Thus,
communication survives the failure of the audio panel.

They didn't do the same thing with the connectivity in the G1000 from
the sensors to the autopilot?

Are you sure that it wasn't the failure of the AHRS1 (which I saw in one
of your photos) which took out the AP? Not that this makes too much of a
difference to the pilot in your scenario, I suppose, but I'm growing quite
curious (in a negative way) during this thread regarding how the G1000 is
architected.

If we assume a bug that causes a G1000 to fail due to bad data coming from
a sensor, for example, then it doesn't matter if we've a dozen G1000s in
the airplane. Dealing with bad design requires diversity as well as
redundancy.

I actually meant "left seat". I've no idea why I reversed it.

But either way, as the sole pilot Emily gets to decide where she sits. In

The Baron (and all Raytheon/Beech products) is considered to be the
"Cadillac" airplane, meaning extremely durable, well-engineered, and
pricey.

Or, to those of us who think it's crazy, they're heavy,
over-engineered, and over-priced.

It's all in the eye of the beholder, of course, but spending $1.7
million for a light piston twin is just stupid, IMHO.

It's all relative. A lot of folks think that about any airplane
compared to a car. You can buy a ratty old airplane for $80,000 or a
brand new Lexus that is 10 times more comfortably and have money left

Well...you've a solution, then. You can be in a relationship with a
pilot as long as he is not a CFI. You get right, he gets left, nothing
remains open for discussion.

I know several single male non-CFI pilots, if you're interested in an

achieve a CFI (which is a flaw in my little scheme, I admit).

Good point. But diversity still helps, lest a design flaw in the one

Software requires diversity rather than redundancy. In practice this
means having two or three or more software packages that perform
exactly the same functions, but are written in different ways by
different development teams. It's unlikely that they will all fail in
the same way at the same time, because they are completely different
internally. This helps make the system more robust.

Something tells me that this concept never even crossed anyone's mind
at Garmin for the G1000.

So when the Garmin system went down, other than HF Communications
provided by a portable transceiver, and the flight controls, the only
other functional instruments and operable systems you had were the OAT
thermometer, EGT, magnetic compass, attitude indicator, altimeter,
intermittent tachometer and airspeed indicator? No navigation
equipment, auto pilot, VHF communications, fuel gages, engine oil
pressure nor temperature gages? Have I finally got it right?

Then the FAA doesn't know how to certify software (or doesn't bother
to do so), which would not surprise me at all.

When the system went down the only things I had was My Portable GPS, HF Com,
Portable VHF Com, Steam Attitude Indicator, Steam Airspeed Indicator, Steam
Altimeter, Whiskey Compass! Every thing else was tied to the G1000 and was
useless or not to be trusted as accurate in that situation. They don't even
have a slip/skid ball in the thing when the G1000 goes blink that's
intergraded also!

I believe after this incident as we see the fleet of G1000 equipped aircraft
age in the next few years there will be many fatalities and/or class action
suite's and whole generation of pilots not prepared for this type of systems
loss!

I hope that this garmin problem never happens to another pilot (I have a
feeling it will and it makes me angry) I am glad I practice partial panel
and have been ferrying airplanes the last year and have gained the skills to
deal with problems such as this. I know it could have gone the opposite
direction really fast and I thank my lucky stars I was able to keep my cool,
work the problem, make the competent decisions and use the resources
available to me to make it in safe!

I like the Avidyne system a lot better at leased if the PFD & MFD fail you
have Comm's, Autopilot, And GPS Navigation all separate! But I only have 10
hours at the controls on a new Piper to make that opinion on the Avidyne
system witch is not enough!

Before everyone jumps all over Garmin keep in mind that what caused
this was the auxilary fuel tank! It created a condition that the Garmin
unit could not handle. But the stock Cessna setup would never create
this condition! I think the real blame here has to be on the auxilary
fuel design. There are LOTS of these Garmin units out there working
very well, very few complaints at all. ALL of the new Cessnas have them
and they are WORKING!

Also keep in mind that the backup systems did work here. He was able to
fly the aircraft on the instruments he had.

It was a *ferry flight* in an airplane which was not supposed to ever
fly over water again. You want full redundancy installed for one ferry
flight? Ok, just don't ferry fly then.

Are we really playing the question game here on r.a.p.?

Do you know how hard it is to keep answering a question
with a question?

What if someone slips and makes a direct statement
that isn't a question?

Will the game end?

Will the thread die?

Will there be film at 11?
