Question

Which of the following is a correct condition when the angle of attack is beyond stalling angle?

(a) Drag is greater than lift

(b) Weight is less than lift

(c) Drag is less than lift

(d) Weight is less than thrust

I had been asked this question by my college professor while I was bunking the class.

My query is from Lift Force in portion Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Right answer is (a) Drag is greater than lift

Explanation: The drag is greater than lift in the condition where the angle of attack is beyond stalling angle. Stalling angle of attack is the angle at which we get maximum lift. Stalling angle is the maximum angle at which the aircraft can be maintained in a steady state.
