Students will learn the purpose of aircraft weight and balance, the procedure for calculating the arm, moment, and center of gravity (CG) of an aircraft. They will identify risks associated with jacking an aircraft, the aerodynamic effect of CG that is forward or aft of CG limits, and the aerodynamic and performance effects of weight in excess of limits. Students will perform weight and balance calculations, calculate the moment of an item of equipment, identify tare items, revise an aircraft equipment list after an equipment change, and determine an aircraft¿s CG range using aircraft specifications.
