Question

Negligible CG change, as specified in AC43.13-1, refers to:

A. Fixed-wing aircraft experiencing a change less than 0.05% of the mean aerodynamic chord, while for rotorcraft, it's 0.2% of the maximum allowable CG range.

B. Fixed-wing aircraft having a change of 0.05% of the mean aerodynamic chord, and for rotorcraft, it's 0.2% of the total aircraft weight.

C. Fixed-wing aircraft with a change less than 0.05% of the total aircraft weight, and for rotorcraft, it's 0.2% of the mean aerodynamic chord.

D. Fixed-wing aircraft encountering a change less than 0.05% of the maximum allowable CG range, while for rotorcraft, it's 0.2% of the mean aerodynamic chord.

Answer 1

Negligible CG change defined in AC43.13-1B indicates less than 0.05% change of the mean aerodynamic chord for fixed-wing aircraft and less than 0.2% of the max allowable CG range for rotorcraft.

Step-by-step explanation:

Negligible CG change, as specified in AC43.13-1B, refers to a situation where the center of gravity (CG) of an aircraft does not significantly shift, thus not affecting the aircraft’s handling or safety. For fixed-wing aircraft, this negligible change is defined as less than 0.05% of the mean aerodynamic chord (MAC). In the case of rotorcraft, the negligible change is less than 0.2% of the maximum allowable CG range. Therefore, the correct answer is A: Fixed-wing aircraft experiencing a change less than 0.05% of the mean aerodynamic chord, while for rotorcraft, it's 0.2% of the maximum allowable CG range.
