The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.

How does an airplane liftoff?

An airplane has two flaps that rotate upward and downward, so when an airplane tilts it's flaps downward, the wind pushes against it and causes it to liftoff.

Why are airplane flaps not used at cruising speeds?

Because although flaps create extra lift they also produce a lot of extra drag which makes the plane inefficient.


What is the use of flaps in airplanes?

Flaps increase the aerodynamic lift of a wing by increasing it's surface area. This allows the airplane to generate a greater amount of lift at slower speeds. In other words, when the flaps are extended, the airplane doesn't have to go as fast in order to take off or land. The flaps are retracted once the airplane is off the ground and has increased its speed to a point where the extra lift from the flaps is no longer needed. Flaps also have the effect of increasing drag on the airplane wing which reduces the airplane's speed and efficiency, but this only affects the aircraft when operating at higher speeds.

Are flaps the ailerons?

No. On MOST airplanes, ailerons are separate from flaps. Ailerons are used to help steer the airplane, while flaps are lowered to change the aerodynamic shape of the wing to provide more lift during take off and landing.


What advantage do flaps and stats give an airplane?

Flaps and stats increase lift for takeoff and slow you down, for landing.

Flaps is the only name, although there are similar devices called slats and spoilers.
