Aircraft manufacturers often account for moveable parts when determining an aircraft's loading envelope. It is not necessary to calculate a separate weight and balance for retracted gear in these scenarios.
CG envelopes that do not account for component movement often provide information related to how the movement affects the aircraft. For example, Moment increase with landing gear retracted 965.0 in lb.
Account for movement not reflected in the loading envelope by following one of the options below.
Option 1: Create a CG envelope that is more restrictive than the manufacturer’s to assure the aircraft is operated within limits during all phases of flight. For example, retracted landing gear that shifts CG forward 0.3" results in a 0.3" reduction of the forward CG limit.
Option 2: Create an additional aircraft profile using the aircraft's basic empty CG with the component in the alternate position.
Option 3: Edit the aircraft's basic empty CG to account for the component in the alternate position.
