One of the main functions of flaps during approach and landing is to
A
decrease the angle of descent without increasing the airspeed.
B
permit a touchdown at a higher indicated airspeed.
C
increase the angle of descent without increasing the airspeed.✓ Correct Answer
Explanation
Flaps increase both lift and drag, which lets the airplane descend at a steeper angle without gaining airspeed and touch down at a lower speed (PHAK Chapter 6). They allow a slower, not higher, touchdown speed, and they steepen rather than flatten the approach.
