Extending the wing flaps increases the wing surface area, which can increase lift at lower speeds by creating more lift-producing air pressure. However, the increased surface area also increases drag by creating more drag-inducing air resistance. Overall, extending wing flaps is a trade-off between increasing lift for lower speeds and increasing drag, which can impact fuel efficiency and performance.

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 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.
What is the zero lift drag coefficient of Boeing 747?
The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.
Why drag increases as lift increase - for helis?
As lift increases for helicopters, the angle of attack of the rotor blades must also increase to generate more lift. This higher angle creates more drag due to increased air resistance and turbulence. Additionally, the higher lift forces can lead to increased induced drag, which is generated as a byproduct of producing lift.
What causes induced drag?
Induced drag is caused by the creation of lift on an aircraft's wings. As the aircraft generates lift, it creates vortices at the wingtips, which result in a rearward force component known as induced drag. This drag increases as the angle of attack or lift produced by the wings increases.
How are the lift and drag components of the wing affected when you lower the flaps?

How does lift and drag effect a boat?
NO!
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 other control surfaces does a plane have then elevators ailerons and the rudder?
Other than the elevators, ailerons, and rudder, airplanes have flaps (which cchange the lift and drag), spoilers (which change the lift, drag, and roll), and slats (which change the lift).
What is an aircraft flap called?
An aircraft flap is simply called a "flap." Flaps are movable surfaces located on the wings of an aircraft. They are designed to change the shape and configuration of the wing during different phases of flight. By extending or retracting the flaps, pilots can adjust the lift and drag characteristics of the aircraft, allowing for changes in speed, angle of descent, and takeoff and landing capabilities. Flaps can be divided into several types, including: Plain Flaps: These are the simplest type of flaps, which extend straight down from the wing when deployed. Split Flaps: These flaps are divided into two sections, with the lower section extending downward and the upper section remaining in place. Slotted Flaps: Slotted flaps have a slot or gap between the wing and the flap, which helps to increase lift at lower speeds. Fowler Flaps: Fowler flaps extend backward and downward, increasing both the wing area and camber, which allows for greater lift generation. The specific type of flap used on an aircraft depends on its design and intended purpose. Flaps play a crucial role in controlling and maneuvering an aircraft, particularly during takeoff and landing.
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.
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.

What is the flape on the plane and how do they help the plane?
the flaps on a plane increase drag and they create lift so the piolt can fly the plane at a lower speed.
What is lift augmentation?
A device to aid lift, such as Slats and Flaps on the wings.
