So I've been running hypothetical W&B situations for the new 1981 172P my club recently purchased. Basically, it's near impossible to put two people in the back pax seat without being aft CG - even when under gross. If you want to check it out for yourself, look at the "Weight and Balance Spreadsheet" on the middle of this page ... http://www.pinellaspilots.org/documents.htm
The issue seems to be the empty weight arm, which is 46.23 - a big difference when compared to the sample arm of 39 an change. If you use an empty weight arm of 39, it pulls the CG back to the middle of the envelope.
So what would explain why the EW CG is so far back? I've checked in the POH and this number was confirmed my a mechanic back in '04. The aircraft is instrument heavy, so if anything, I would have figured for a more forward CG.
Just curious - it's making me leery about sticking two women in the back.
