Weight and Balance Determination for Flight
This part describes the procedure for calculating the weight and moment for various phases of a planned flight
and ensuring the center of gravity is within approved limits. To calculate the weight and moment of a loaded aircraft
use a Weight and Balance Loading Form (Chapter 6.4.2).
Aircraft Weight and CG Limits
The charts on Fig. 6-2 (Metric Units) and Fig. 6-3 (U. S. Standard Units) depict the aircraft
’s operational
CG envelope in
the terms of CG arm aft of reference datum and as a percentage of the MAC. The relationship between CG arm and
percentage of the MAC is detailed in the Chapter 6.2.3.
