View Full Version : Re: Gear Warning
Gordon Schubert
November 18th 05, 08:21 PM
I had gotten an almost brand new (12 hrs) Genesis 2.
My experience with retractable landing gear was somewhat
limited. At the end of my sixth flight I crossed the
field to check on traffic and turned into the pattern.
I announced my downwind and started my landing checklist.
Just as was about to drop my gear an ultralight pulled
into the middle of the hard surfaced runway and stopped
and just sat there. As I was contemplating what to
do (I land on the hard surface because of gopher holes
on the narrow grass strip and rough ground) a power
plane announced that it had entered it's downwind for
the same runway. I was now 2/3 thru my downwind. Just
as I was turning to base, our Grob two place motor
glider's pilot called that he was coming in for an
emergency landing. He had smoke in the cockpit. So
now I was looking for him also. It turned out that
he was behind me as I turned to final and I decided
to land long on our 3500 ft runway.
On final the runway looked clear, the ultralight had
taken off in front of me and I started to relax. As
I came in over the end of the runway at about 100 ft
I saw everyone waving at me and thought of how nice
it was of them to do that. I was getting lower and
started to flare and it hit me. S***, my gear! I slammed
the spoilers shut and in one quick motion shifted my
left hand to the stick and my right hand rammed the
gear down. Fortunately, I was able to get it locked.
I hit the ground a split second later. My friends that
were watching said that I was 4-6 ft off of the ground
when the gear came down.
After this adventure, I spoke with 2 of our instructors
seeking advice on what I could do to prevent this from
happening again. One of them suggested something that
he said military pilots sometimes use.
When I announce my downwind, at the end of the announcement
while still on the radio I also say 'Gear is down and
locked'. I have not had another incident since, but
I still intend to install a gear warning system. Not
only would it have gone off when I first checked my
spoilers upon entering downwind but again on final.

How about just doing your pre-landing checks properly.
You only need to check 4 things: water-ballast, U/C,
loose-articles(straps) and flaps. It takes seconds.

What about radio, speed, trim, spoiler, traffic and landing area?
No doubt checklists reduce the chance for errors, but it is naive to
believe they will always save your butt, cause when something goes
wrong, which result in distraction, first thing you'll forget/skip is
your check list...

They don't need a checklist, they are part and parcel
of flying your glider. Change speed - trim, lookout
for other traffic - basic airmanship. If you need
a checklist for them you're going to have problems.

I agree traffic and landing area may not need checklist, but definitely
checking radio frequency and volume, trim for pattern speed and checking the
spoilers must be part of every landing checklist.

Personally, they are not part of my pre-landing checks.
If I've been flying in icing conditions (wave) I'll
try the airbrakes on the way down, apart from that
it is not necessary to check them prior to landing.
I don't adopt the approach speed until just prior
to base leg and I always trim after changing speed
whenever I'm flying, so why have it as part of a checklist?
The radio check may be valid in the States but isn't
necessary in the UK.

To ensure they do operate (freezing shut is not the only way for them to
fail) and to activate the gear warning device.

Is that because the field frequency is the same as the one you use
during the flight, or because the glider fields you use don't use a
radio in the pattern? I'm assuming you'd use the radio at a regular
airport with mixed traffic.

If you checked your airbrakes at the DI and prior to
take-off, and you have not been flying in icing conditions,
they will open when you want them to. I've never heard
of airbrakes failing in flight and if they did so what?
You'll find out when you unlock them on base leg.
As for opening them to activate the gear warner, well
that sounds a bit Irish to me. How about carrying
out the gear part of the checks? The radio is not
a necessary part of pre-landing checks, I and any other
glider pilot in the UK would be very unpopular if they
landed at an airport; and if you were tempted to, the
radio call should be made well before the point at
which the pre-landing checks are carried out. (Most
glider pilots in the UK do not have RT licences and
so couldn't legally make the calls anyway).
The point I'm trying to make Eric is that for checks
to be effective and not missed, they should only include
those things that are really necessary to check. The
pre-landing checks I, and a lot of clubs use, are WULF:
waterballast, U/C, loose articles(including straps)
and flaps. In my opinion that is all you need to methodically
check to make a safe approach and landing, anything
else (apart maybe for radio in the States, as you obviously
do land at airports) is superfluous.
I also think these checks should be done prior to joining
the circuit, so that there are no distractions from
carrying them out and so that full concentration can
be given to flying the glider around the pattern and
looking out for other a/c on the ground and in the
air.

I have had only one spoiler deploy. I was glad I checked them early because
it gave me the opportunity to extend the downwind a bit to compensate.
But, you are right. This is very rare. A more justifiable reason to check
the spoiler/airbrake is to insure your hand is on the right control. Once
you hand is on the airbrake control, keep it there through the rest of the
landing. Yes, I know, you should LOOK at a control before placing a hand on
it but we all know of accidents/incidents where the wrong control was
selected.

The Americans seem to use the word "airport" to mean what we would call
an airfield, and that includes grass strips.
To us Limeys, an airport is something like Heathrow, or JFK.

Mark, the radio check is not transmission check (although announcing
you are in the pattern is always a good idea), it is frequency check (I
often hear pilots calling their pattern on the wrong frequency they
used for air to air), and volume check to make sure your volume is not
down since your last low save. I am very suprised to hear that most
pilots in the UK can not use the radio legally, or am I missing
something?
I agree the list should kept to minmum, but your list has an item which
very much belongs to takeoff checklist, not landing list, unless I
missundersood it: Loose articles (including straps) - I rather
eliminate those *prior* to take off.

I had the airbrakes on a Blanik fail to open on the pre-landing checks,
even though they operated correctly before takeoff. The sheet metal lip
caught on the edge of the spoiler box, a problem that didn't show up in
the heat of the afternoon. So, I'm sensitive to this. I agree it's rare.
> You'll find out when you unlock them on base leg.
Base leg? I generally don't open them until I turn final. I don't like
opening them on base leg because it makes the turn to final occur at a
lower altitude, and it raises the stall speed. I will open them on the
base leg, or even downwind if it's very important to land as soon as
possible, but not for a normal landing.

Great idea, which I fully support, but in the first 1500 hours I flew, I
missed it three times due to distractions. I know other pilots that
have also done the same thing, and are pleased they had a gear warner. I
don't know any pilot that is unhappy he installed one. The UK position
was quite a surprise to me. If US pilots routinely landed on grass
fields instead of paved ones, perhaps they would not like gear warners
so much.

This is very different from the situation in the US, where flying from
and landing at public airports is common (mostly non-towered municipal
airports). We are expected to announce our intended landing at the
airport from about 5 miles out, then pattern entry, and typically the
turns to base and final. The frequency is different from the glider
frequency. Doing it on the wrong frequency isn't useful. A license is
not required in the US.

Agreed.

Agreed. I typically do them on the 45 degree entry to the downwind leg,
or the crosswind leg.
