A. When the weight or torque of the aircraft change, illustrate how to keep this record in order to save the exact initial values to measure the weight and heavy center in normal flight.
B. Explain how to maintain this record when changes to the weight or moments of the airplane are made so that accurate starting data is available to calculate the weight and center of gravity during normal operation of the airplane.
C. When the changes to the mass or momentum occur, show the way to hold this record to get the beginning information easily to compute the mass and gravity core.
