Basically they 'curve' the wing, forcing the airflow to lift more weight.

What advantage do flaps and stats give an airplane?

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


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.


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.


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.


What are the purposes of the slats and flaps of an airplane's wings?

Slats and flaps increase drag and also increaselift. The increase in drag slows the aircraft down, and the increase in lift lowers the stall speed, which slows the landing speed of the aircraft.


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.


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)


Where are the flaps on a plane?

They are on the trailing edge of the wings. They are used to increase drag and can increase lift. If set to a large enough angle the amount of drag exceeds the added lift and allows a plane to land a slow down in a shorter distance than it could in a no flap condition. Flaps assist on allowing an airplane to fly at a slower speed and maintain lift and control.


When are the flaps on an airplane most useful?

They are useful for takeoff to get lift and at landing for slowing down the plane.


How are the lift and drag components of the wing affected when you lower the flaps?

lift decrease and increase drag


What is the device in an aircraft wing to reduce lift and decrease speed?

Airplanes use a combination of slats and flaps in order to increase lift and increase drag. The slats are located on the leading edge of the wing and the flaps on the trailing edge. Flaps and slats when extended forward and aft increase the wing area which increases lift. When the flaps and slats are further extended they curve downwards increasing the camber of the wing which also increases lift. The greater the lift, the greater the drag. Deploy the flaps a little and lift overcomes the drag, fully extend them and the drag overcomes the lift. For takeoff the flaps and slats may be extended just a few degrees to increase lift. When flaps and slats are fully deployed in landing configuration, the lift is great but so is the drag and this in turn helps to slow down the airplane on decent to land.
