I'm looking for an example of a W&B worksheet using CG arm values instead of
moment values. Basically, I'm curious to see how these are done and what
the worksheets look like.

Either online or emailed examples are acceptable.

Thanks!

If you can use Excel, you can easily construct your own W&B worksheet.

Put the weight of each component in column "A", its arm in column "B",
its resultant moment in column "C".

All you have to do is multiply column "A" by column "B" in coulmn "C",
add the sum of columns "A" and "C", divide the sum of column "C" by the
sum of column "A" and you have the CG in column "B".

You can get better by adding fuel in gallons, converting it to lbs in
the weight computation, oil in qts, converting it, etc.

You can build pax/fuel loading scenarios and get a real handle on what's
going on.

It is really quite elementary.

A year ago I helped a retired AA captain build a W&B program for his
plane -- it really opened his eyes!
