Which of the following is true concerning flaps?

1. Flaps are attached to the leading edge of the wing

2. Flaps increase lift and drag simultaneously

3. Flaps allow an increase in the angle of descent without increasing airspeed

4. Flaps are only used during takeoff

The correct answer is: Flaps allow an increase in the angle of descent without increasing airspeed

Flaps are integral components of an aircraft's wing that enhance performance, primarily during takeoff and landing phases. When deployed, they change the wing's airfoil shape, increasing both lift and drag. The true statement regarding flaps is that they allow pilots to increase the angle of descent without significantly increasing airspeed. By extending flaps, an aircraft can descend at a steeper angle while maintaining slower airspeeds. This is particularly advantageous during the approach and landing phases of flight, allowing pilots to manage descent paths effectively without risking a stall. This capability provides safer landing approaches, especially in situations where obstacles are present or when short runway distances are a concern. While flaps do increase lift and drag, their ability to allow a steep descent without increasing airspeed is a key operational advantage. Additionally, flaps are not restricted to use only during takeoff; they are primarily used during the landing approach as well, making the claim that they are only used during takeoff inaccurate.
