Question

The Free Elevator Factor (FEF) primarily indicates

• A. The reduction in stick-free longitudinal stability compared to stick-fixed stability
• B. The increase in elevator deflection due to pilot input
• C. The maximum nose-up trim angle of the aircraft
• D. The ratio of tail lift to wing lift

Hint:

Generally, \[ \boxed{ \text{Stick-fixed stability} > \text{Stick-free stability}. } \] The Free Elevator Factor accounts for the reduction in stability caused by the elevator floating freely under aerodynamic loads.

Answer 1

The Correct Option is A
