Where are ailerons located on an aircraft wing?

Ailerons are specifically designed to control the roll of the aircraft, allowing it to bank to the left or right during flight. They are strategically placed on the trailing edge of the wing, which is the rear part of the wing that extends away from the aircraft fuselage. The correct placement of ailerons furthest from the fuselage is instrumental in providing effective control over the aircraft's lateral movements.

When the pilot activates the ailerons, one aileron moves up while the other moves down, creating differential lift across the wings. This differential action is crucial in helping the aircraft to roll and change direction effectively. Their position on the trailing edge, away from the fuselage, maximizes their effectiveness by ensuring that the lift forces generated by each wing can be differentiated and utilized to control the aircraft's roll more efficiently.

Other options do not accurately describe the function or placement of ailerons in relation to aircraft wing design and control surfaces.
