Accepted Answer

During a stall, the lift...

Answer

Increases and drag decreases.

Answer

Increases and drag increases.

Answer

Decreases and drag decreases.

Question 6

Compared to trailing edge flaps, leading edge devices like Slots...

Accepted Answer

Produce less drag while allowing a higher angle of attack.

Answer

Reduce the critical angle of attack at a given speed.

Answer

Allow higher speeds at take-off and landing

Answer

Increase the camber and allow a lower angle of attack.

Question 7

Which statement concerning the angle of attack is correct?

A too large angle of attack may result in a loss of lift

Answer

The angle of attack cannot be negative

Answer

Increasing the angle of attack results in decreasing lift

Answer

The angle of attack is constant throughout the flight
