flap
Quick Summary
Flaps are crucial aircraft parts that extend from the trailing edge of a wing. Their primary function is to increase both lift and drag, which is particularly important for landing at lower speeds. By deflecting downwards, flaps can significantly alter the wing's characteristics.1
There are various types of flaps, including split flaps, Fowler flaps (which increase wing area by deploying on tracks), and leading-edge flaps like the Kreuger flap. These devices can also be used to increase drag for deceleration during descent, landing, or after landing. The angle at which flaps are deployed influences whether lift or drag is primarily increased.2
