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.

What do flaps help an airplane do?

An airplanes having the flaps in wings as it helps the plane to give or to produce a additional lift.


How many flaps do an airplane have?

Generally speaking airplanes have 2 flaps, one on each wing. More complex aircraft such as airliners & even many biz jets will also have leading-edge flaps, bringing the total to four. (I'm a nerd at airplanes so I know this is certain.)


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.


Does a plane have to have flaps deployed on takeoff?

No. Not always. For many airplanes, it may be required if the airplane is fullly loaded.


How does airplanes land?

The pilot throttles back, (slows the engine), extends flaps, and lets it sink slowly onto the runway.


How do airplanes come down?

They reduce engine speed and extend 'flaps' which allows the wing to keep lift at lower speed.


Why do you use model airplanes?

People use model airplanes because they like airplanes or the look of them.

Flaps are used to increase wing area?

Flaps in some cases are used to increase wing surface area. In most small single and multi-engine airplanes the flaps that are being utilitized usually plain, split or slotted, do not increase the surface area. They increase the camber (camber being the distance between the mean thickness of the wing and the line going from the leading edge to the trailing edge (called the chordline)), and also increase the coefficient of lift (or how hard the wing is working to produce lift). On most transport category airplanes they utilize what is called fowler flaps. These flaps increase the surface area of the wing by moving the flaps rearward on a track. This rearward movement increases those things stated earlier and also increased the surface area, which also produces more lift.


Do you use flaps to land an airplane?

Yes, Flaps are both used to create lift (on takeoff) and to slow the aircraft (on Landing)


Take off without flaps?

Yes, it IS possible for most airplanes to take off without using flaps, but it is usually not done because airplane would need a longer runway or more speed before the wings could create enough lift to get off the ground.
