Which flight phase requires the use of flaps?

The use of flaps is essential during the landing and takeoff phases of flight, making this the correct answer. Flaps are adjustable surfaces on the wings that increase the wing's lift and drag characteristics. When an aircraft is taking off, flaps are extended to allow the aircraft to become airborne at a lower speed by generating additional lift. This capability is particularly crucial during takeoff, as it ensures that the aircraft can ascend safely and efficiently.

During the landing phase, flaps are also deployed to reduce the landing speed and improve the aircraft's ability to maintain control while descending. The increased drag created by the flaps helps the aircraft to descend at a controlled rate and allows for a steeper descent angle, which is beneficial when approaching a runway without gaining excessive speed. The combination of these factors helps ensure safe and effective takeoff and landing operations.

In contrast, the climb and cruise phases typically do not require flaps as the aircraft is operating at higher speeds where flaps are retracted to reduce drag and maximize performance. During descent, the primary focus is on managing the aircraft's speed and altitude without the need for additional lift provided by flaps. The approach phase may involve the use of flaps, but it is part of the broader landing
