On mostly the larger aircraft, when you bank the plane either right or left the ailerons move like normal, like for a left turn the left one goes up pushing the left wing down and the right one goes down pushing the right wing up. but the aircraft is so heavy and big that it needs a little help, so along with the aileron they also move the outer flaps down a little on that wing to help push it up. they also use the spoilers on the left wing to help push that wing down. its all just enough to make the plane bank easier.


Another answer:

In order to make a proper turn in an airplane, the pilot first uses the ailerons to roll the aircraft in the desired direction. The ailerons will make the aircraft tend to yaw in the opposite direction due to the asymmetric drag they create (adverse yaw) and so the pilot will use the rudder to compensate.


Once the airplane is rolled to the desired bank angle, the pilot will then apply some nose-up pressure on the elevators to maintain altitude and press the rudder into the turn to maintain turn coordination. You can make a turn without rudder, but the aircraft will tend to "skid" (the tail of the aircraft doesnt exactly follow directly behind the nose, like sliding around a corner in the snow) which is considered very sloppy flying.


Once the turn is complete, the pilot will use the ailerons to level the aircraft, once again using rudder to compensate for adverse yaw, and providing the aircraft is trimmed for the desired attitude, release the upward pressure on the elevator.


Of course during the turn the pilot may have to make other adjustments to the aircrafts attitude using the control surfaces, such as maintaining the desired bank angle and correcting for wind gusts or air pockets.

(Additional comment to clarify good answer) Once the desired angle of bank is attained, the pilot will more or less centralise the yoke again, whilst maintaining the pressure on elevator and rudder, as he doesn't want the bank to increase any more. This is unlike driving a car when the steering wheel remains turned until the driver wants to exit the corner. A pilot will then apply opposite bank input to get the plane back straight and level again.

The questioner asks about "flaps". Since a "flap" is a specific flying control on an aeroplane, distinct from ailerons elevators, rudder and trim tabs, the question would be better put in asking about "control surfaces"

What are threads that attach the valve flaps to the ventricle walls called?

The threads that attach the valve flaps to the ventricle walls are called chordae tendineae. These fibrous cords help to prevent the valve flaps from prolapsing or collapsing back into the atria during the contraction of the ventricles.


What are Nasal flaps?

Nasal flaps are a surgical technique used in reconstructive nasal surgery to repair defects in the nose. A flap of tissue, usually from the forehead or cheek, is transferred to the nasal area to help reshape the nose and correct deformities caused by trauma, cancer removal, or congenital abnormalities. Nasal flaps allow for more natural-looking and functional outcomes compared to other reconstructive methods.


What are the the tiny white cords that anchor the cusps or flaps of endocardium to the walls of the ventricles called?

The tiny white cords that anchor the cusps or flaps of endocardium to the walls of the ventricles are called chordae tendineae. These cord-like structures help prevent the cusps of the heart valves from prolapsing into the atria when the heart contracts.


What have two or more different kinds of atoms linked together?

A molecule is formed when two or more different kinds of atoms are linked together by chemical bonds. These bonds can be covalent, ionic, or metallic, depending on the nature of the atoms involved and their arrangement.


What is it called when two or more species live together in a close long term association?

If you mean when two different organisms live closely together and help each other survive, then it's symbiosis.

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.


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.


A plane usually extends flaps from its wings during takeoff and landing What is a reasonable explanation?

The flaps help to increase lift, which is essential to the landing and takeoff phase[s].


What would happen if you deployed flaps during flight?

The aircraft would nose-dive ! The flaps are used during flight to help the plane gain or lose height in conjunction with the engines.


What are those flap like things that open on an airplane's engine when it lands?

You got it in one they are flaps. the wings have flaps and ailerons and sometimes an extra control surface that goes upwards to help it slow down. In any case the flaps are the control surfaces on the back of the wing that move down as the plane slows down to land. they stop the plane from stalling and falling out of the sky. a very irritating thing if it happens especially when you are close to the ground. by using the flaps the plane is able to keep flying at a lower speed prior to landing. if there were no flaps the plane would have to come in at high speed or fall out of the sky.


What is the flapper on the plane and how do they help the plane?

Flaps are the devices that extend off the back of the wing. They are used for take off as well as landing. They increase lift and reduce the speed at which airflow over the wing is disrupted, thereby resulting in a slower approach and landing speed.


Why is it preferable for planes to take off into the wind as opposed to with the wind?

The wind is required to pass over the wing to create a vacum which lifts the plane. Flaps are used to extend the wing surface to help with lift


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.


Why do some animals have large ear flaps?

Large ear flaps in some animals, such as elephants, are important for regulating body temperature. The blood vessels in the ears help dissipate heat, allowing the animal to cool down. Additionally, the ear flaps can help amplify sound for better hearing.

Do mud flaps reduce the amount of rocks that get kicked around?

Mud flaps are usually used to help with rocks and mud from building up underneath near the wheels.


What do the wings and flaps help a plane do?

As the engines compress and ignite a fuel air mixture, and then blow it out the back to push the plane forward, air rushes over the wings. because of the wings shape, the air is thinner above the wing and more air is being pushed down. This creates thrust. So when the pilots pull back on the control yolk, small pannels bend on the back of the wing either up or down, making the plane point eaither up or down, and the engines push the plane forward while the wings keep the weight of the aircraft aloft, as long as the plane maintains a certain speed, known as its stall speed. Flaps are larger panels that create drag (if the pilots use them, or else they lay flat) and slow the plane down, but they also create lift. so its a give and a take. This makes planes slower yet "floaty" on approach. Hope that helps I'm just 14.ANS 2 - Wings and flaps give 'lift' to an aircraft.
