Ailerons are hinged control surfaces attached to the trailing edge of the wing of a fixed-wing aircraft. They are used to control the aircraft in roll. The two ailerons are interconnected so that one goes down when the other goes up: the downgoing aileron increases the lift on its wing while the upgoing aileron reduces the lift on the other wing, producing a rolling moment about the aircraft's longitudinal axis. The word aileron is French for "little wing."

Ailerons move up and down. These are small surfaces, usually on the outboad trailing edge, but sometimes there is another one in the middle of the trailing edge. They are used to roll the aircraft.

Flaps move down only, usually at the inboard trailing edge, but sometimes there is a small aileron between two flaps. These are large surfaces. Some flaps consist of several separate flaps that expand as they move down. They allow the aircraft to fly at a lower speed.

Spoilers are ahead of the flaps only and they only go up, they are used for slowing and decending the aircraft and to help the ailerons roll the aircraft.

Kruger flaps and slats extend downward from the leading edge of the wing and they help the plane fly slower for takeoff and landing with the flaps. They are fairly small surfaces.

Some aircraft like the F-14 have the entire wing move back and forth for high and low speed flight. The F-8 (a really old jet) moves the whole wing to change its angle on the fuselage.

On the trailing edge of the wing (the back) are the flaps (closer to the fuselage) and the ailerons. The flaps help to slow the aircraft, the ailerons steer it. On the top of the wing are speed brakes, and at the front are leading edge slats, which increase lift.

On the back of the wing it's ailerons. On the front of the wing it's slats. On the bottom of the wing it's the flaps. On the aileron itself there are trim tabs.

I am taking it you are speaking of the main wing. There are several moving parts. the main moving part is the aileron. But there is also an inboard flap, inboard spoiler, tabs, outboard flap, and outboard spoiler. Use in combinations they provide breaking or extreme lift and stability ti=o the aircraft.

Yep, flaps in the rear, close to the fuselage, ailerons in the rear, outboard, slats in the leading edge, and speed brakes on top.

And Christain, little wing in French translates to peu d'aile.
Flap translates to aileron.

All of them are called "Flight Control Surfaces"

There are several possible moving parts of a wing.

Ailerons, flaps, slats and speed brakes are all possible answers.

And on a helicopter, the wings themselves are moving parts.

Perhaps you are thinking of a flap. Wings have flaps on them that move up and down. This is either will give the plane lift if the flaps are tilted down and it will provide for dissent if the flaps are tilted up. I hope this helps.

Your toddler would be merely super. I honestly have 4 cockatiels and that i save their wings clipped. in case you basically further him domicile he's possibly merely in marvel from the substitute. i recently further domicile 2 new cockatiels ( some weeks aside) and for the 1st week they slightly moved. 2 months later i can't get them to sit down nevertheless. by way of the way - my 4th cockatiel has merely decrease back domicile after being long previous for 2 months. We did no longer clip his wings and he flew out the lower back door. we are very fortunate to have got here upon him. be valuable to maintain those wings clipped - it extremely is for the excellent. take excitement on your new chum and love him bunches!!!

ailerons for the roll axis, flaps for lift and drag, speed brakes for landing and braking.
