They don't really need them to fly. However they are very useful for keeping a plane flying when you slow it down on landing and using flaps on take of means that you reach flying speed at a lower speed. The runways would have to be a lot longer if planes had to land and take of without flaps because they would have to land flat out at air speed.
What else can I help you with?
What do the flats on a plane do?
They are called "flaps" and they allow the airplane to fly at slower speeds
What advantages do flaps and slats give an airplane?
The Flaps And Slats Give An Airplane More Lift At Low Speeds.
How does airplane flaps work when airplane is climing?
The flaps create more lift when fully extended and the aircraft is climbing.
How do you make a airplane?
You will need 1 paper and fold it hotdog then do to flaps then seal it then make wings!!
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?
Airplane flaps are used during takeoff and landing to increase lift and drag, which helps the plane to reduce speed for landing and take off. At cruising speeds, the airplane is already flying efficiently and has no need for the extra lift and drag provided by the flaps.
Why does airplane need gas?
so it can fly
What are the flaps on a airplane wing called?
winglett
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.
What are the flaps on an airplane used for?
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 a fly fly in the air?
flaps its wings
Can people fly above the troposphere?
no, you will need an airplane,(people can't fly).
