Quiz: Can You Answer These 7 Stall Questions?

Boldmethod

Can you make it through all 7 questions without stalling?


  1. 1) As an aircraft's weight increases, its stall speed ______.

    The heavier your aircraft, the higher the angle of attack it needs to fly to maintain altitude. Because of this, you're closer to the critical angle of attack at any airspeed, and you'll reach the critical angle of attack at a higher speed.

  2. 2) Most straight wing aircraft are designed to stall at the _______ first.

    Most aircraft are designed to stall at the wing root first. This gives the aircraft more controllability, and less of a tendency to roll left or right during the stall.

  3. 3) Stall speed is _____ in a level turn than it is in straight-and-level flight.

    Stall speed is higher in a level turn, because a higher AOA is required to create enough vertical lift component to maintain altitude.

  4. 4) A stalled wing produces lift:

    Even though a wing is stalled, it still produces lift, although the lift falloff is rapid as the wing enters the stall.

  5. 5) Stall strips are designed to _______ a stall directly behind the strip.

    Stall strips make it harder for airflow to stay attached to the wing at high angles of attack, creating a stall directly behind the stall strip.

  7. 7) As an aircraft's weight increases, its maneuvering speed (Va) ______.

    Because a heavy aircraft flies at a higher angle of attack, it will reach the critical angle of attack sooner when a full control input is placed on the aircraft. Because of that, Va increases as the aircraft's weight increases.
