Question

Leading edge flap deflection has the effect of increasing lift curve to a higher stalling angle of attack.

(a) True

(b) False

I had been asked this question in examination.

The origin of the question is Lift Force topic in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

The correct choice is (a) True

To explain I would say: Leading edge flap deflection has the effect of increasing lift curve to a higher stalling angle of attack. This helps in reducing the take-off and landing speeds of the aircraft.
