Throw a Weight in the Back?

Just a guess, but I am probably carrying about 138 more pounds in the fuel
tanks than the 182L (65 gallon tanks?). This aircraft is a 1979 Cessna 182Q
with 88 gallons of useable fuel. Thanks for eveyones feedback!

I'm suspicious of your calculations or W&B info. In my 182L, there
is no way I can get out of the envelope with 430# forward, nothing
aft, regardless of fuel load.

I have 79 gal (long range tanks) in the L model.

I have flown several Q models owned by the CAP, and they make us work
the W&B before each flight. I still dont remember that any of them were
close to the front limit even with two lard asses in the front.
(Takes one to know one: I'm 210#)

I'm still suspicious of your numbers.
Perhaps the empty weight and moment on your Q got messed up somewhere
along the inevitable added/removed chain.

Mike:

I'll have to dig a bit further beyond the spreadsheets, calculator, and w&b
insert that we have for this airplane (logs, etc.).

I have found two CAP C182Q aircraft on the web that weigh in at 1831 lbs.
and 1848 lbs. respectivly with 88 gal. useable fuel. Loaded with 430 lbs for
pilot and copilot they are within limits according to the documentation for
those airplanes.

It could be, as suggested in other posts, that the empty aircraft moment/arm
is off.

Regards,
Kirk

I have a small tank in the base of my glider fin. I fill it
with water when needed to get the W&B correct.

When ferrying the Lockheed L1649, we used to have to
load 4000 pounds of water in 55 gallon drums AFT of
the rear cabin door. Without that weight in the tail
and a hydraulic boost failure, you couldn't get the
nose high enough, or tail low enough, to keep from
landing on the nosegay first.

Sorry about the mistake - meant "nosegear".

Yes. In my Sundowner I put weight in the back .. helped a lot.

In a Bell 47 for solo I used to put weight down in the bubble in
front of copilot pedals. I was a lot lighter then. ;-)

Anyone ever throw a weight in the back to get within allowable weight and
balance? I am flying a C182 with 430 pounds (pilot & passenger) in the
front row. The point is I would like both of us to sit up front for the
flight. I have other aircraft that I can fly, and this is not a required
flight (no safety flaming please).

Calculated arm is 37.99, and minimum arm at that weight is 38.15. I am
144.85 pounds UNDER gross weight at this point.

If I throw a 20 pound weight in the main baggage compartment the arm is
38.4
(meets the minimum requirements) and we can both sit up front.

Kirk,

Sounds like you have an extra nose heavy 182, but that happens from
time to time. With fuel burn on that airplane the c.g. does not move
much during flight, so it's time for uou to toss some weight aft
(which will also make the airplane faster in cruise.) If you have a
heavy flight case, as many pilots do, strapping it into one of the
rear seats may take care of it for you.

When I flew freight in the Cessna 404 the airplane was out of c.g.
forward with just a pilot aboard, so I carried two collapsible, five
gallon water jugs. When the airplane was empty I filled up the jugs
(there's always a spigot somewhere on the airport) and put them under
the baggage net in the back end of the airplane. Once I got the
freight, if it took me to gross, I dumped the water. Otherwise I just
moved the jugs forward if needed to keep the c.g. from going out the
aft end if I knew I had another empty leg coming up.

I've still got the jugs and use them for camping trips, but haven't
flown an airplane in quite a while in which I needed them for c.g.
adjustment.

All the best,
Rick

The real question is how do you go out the front limit with weight
anywhere else in a 182 besides the front seats? With full tanks and 430
pounds in my 182's front seats I do not go out the front limit. Any
weight anywhere else moves it back. Removing some fuel is another option.

Or in the front (our usual), or any place where it's needed.

Sure. It's no problem. Just, if you need it to be at the right
station for a critical reason, make sure it's an accurate weight
and make sure it's strapped down so it can't relocate itself
at a critical moment. We once had a dog, thought to be strapped
in the rear seat, relocate herself to the baggage compartment
on short final. Fortunately in the plane we were flying it only
improved the flare, in today's plane it would be ruinous.

Just identify something you can use (dogfood, driveway salt,
sand) toss it in and strap it down. If the plane you're flying
doesn't allow secure strapping of a purchased bag, throw 'em in
a duffel and strap that down.

If you need 20 lbs to be "just within", personally I'd throw
30 or 40 lbs in the baggage and be comfortably within. The
W&B tends to be a little inaccurate as planes age (unrecorded
instrument or radio changes, engine accessory changes etc)

Best,
Sydney
