Procedure for calculating weight and balance

Mxsmanic,

which nobody seems to care about except me)


Ah, time to take a clue, isn't it?

Why would "neutral trim" be important? For that matter, what would it
be?

What you get is a range of allowable CGs, which often depends on total
weight. This all has to do mostly with elevator authority. Trim (as in
the trim wheel) is not really important, trim is just a tool to relieve
the pilot. Trim as in weight distribution, well, see above.

Once you've figured this out, ponder why an aircraft will be faster or
consume less fuel if the CG is as aft as possible.

also check faa.gov AC-61-238 "Pilots' Handbook of Aeronautical
Knowledge" will answer all your questions (I hope).

Section 12 explains the principles behind it, but it didn't actually
say how to calculate the center of gravity, or how to achieve neutral
trim (which nobody seems to care about except me).


as you burn fuel your CG changes. Your 'neutral trim' wont last. read
about the benifits of forward/aft CG's.

Now if your doing areobatics I believe the placement of the CG becomes even
more importent (all I have done is spins) and my guess is that a 'neutral
cg' is not the best place?
