Statement I: An angle of attack based stall warning is valid at any aircraft weight.

Statement II: Stall occurs at a fixed indicated airspeed regardless of weight.

In the light of the above statements, choose the correct answer.

  • A.Statement I is correct but Statement II is incorrect
  • B.Both Statement I and Statement II are correct
  • C.Both Statement I and Statement II are incorrect
  • D.Statement I is incorrect but Statement II is correct

Answer: A

The first is correct and the second reverses the physics: stalling speed rises with weight and load factor, while the stalling angle of attack stays essentially fixed. That is precisely the argument for sensing the angle rather than the speed.
