Divide the TM (total moment) by the TW (total weight) to obtain the loaded center
of gravity.

The above computations show that with maximum baggage, full fuel and 2 passen
gers (1 in the front seat and 1 in the rear seat) may be carried in this aircraft without
exceeding either the maximum weight or the approved C. G. range.
This condition may be entered in the loading schedule as follows:
