the wing flap
It is just called the wing.
The flaps are simply called flaps.
Mono plane.
A flap on a plane moves by extending downward or backward from the wing surface. This increases the wing's surface area and changes its shape, which helps to generate more lift at lower speeds, allowing the plane to take off and land more slowly and safely. The pilot controls the flaps using the cockpit controls.
the main parts of an airplane is 1.the propeller without it it can't fly 2.rudder 3 right wing flap 4 left wing flap 5wing 6 landing gear 7landing wheels 8tail of the plane
a single winged plane is called a monoplane
MY ANSWER: The aileron is on the far end of the wing while the flap is on the inside of the wing. now you might think that these 2 are similar but in ways they arent. The aileron help the plane to spin bank and tilt, while on the other hand the flap increases lift or decreases drag for take off and landing. Hope this helped :)
Aileron
To provide the lift necessary for flight.
It sounds like you are referring to what is called flap track fairings. There are usually several of them on the underside of each wing, and taper to a point at the back. These are covers for the flap tracks- the mechanical mechanism that allows the flaps to extend and retract. Without them the flap components would be exposed and create drag.
