Been doing some weight and balance on a Cessna 172S recently and have come across a (very) worrying problem. On Page 6-15 and 6-16 of the POH there are the figures for Centre of Gravity Moment Envelope and Center of Gravity Limits. Important stuff I'm sure you'll all agree!
I'm planning in metric here in Australia and using the Kilogram scale on the right of each chart. Could't get three adults and full fuel to work the other day, so checked the calcs in lbs and not Kgs; this time it worked!!
Looking at figure 6.7 and 6.8 there is clealry an error in the kg/lbs conversion; one of the scales is wrong! The revision number in the POH is May 30/00.
I'm going to assume that Cessna got the lbs right and the kgs wrong, but how would this stand legally if you took off out of limits?
