How hard is the math for calculating CG?

I was in the Air Force for a time, working on the C-5, C-17, and KC-10. We had to figure CG when jacking the aircraft, but we just had a handy chart and plum line that did most of the work for us. Never had to do it from scratch before.

I just realized my answer above was a bit generic, and you asked specifically about A-10's...

On an A-10 the desired CG location is actually fairly easy to calculate, because the Mean-Aero-Chord (MAC) is basically the same as the wing root chord. This is because the wing is simple, straight and (almost) entirely a rectangle. So the 25%-MAC point is basically just 25% of the root chord (measured from the leading edge).
