Solution

The answer is b. Increase the rate of descent.

Here's why:

  1. Flaps are control surfaces on the wing of an aircraft that help to increase its lift. They do this by changing the shape and surface area of the wing, allowing it to generate more lift at slower speeds.

  2. When you lower the flaps in a glide, you're increasing the drag on the aircraft. Drag is a force that opposes the motion of the aircraft, and in this case, it's working against the lift that's keeping the aircraft in the air.

  3. Because of this increased drag, the aircraft will start to descend more rapidly, even if you're maintaining the same indicated airspeed (IAS). This is because the extra drag is pulling the aircraft down faster than the lift can keep it up.

  4. Therefore, lowering the flaps in a glide while maintaining the same IAS will increase the rate of descent.
