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

The above computations show that with the maximum number of passengers, 39
gallons of fuel and zero pounds of baggage 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:
