Usage: aviation/aeronautics; technical term

Examples

• The flaperon on the wing's trailing edge helps the pilot adjust both altitude and banking angle.
• Modern aircraft often use flaperons to simplify wing design and reduce weight.
• During takeoff, the pilot extended the flaperons to increase lift.
• The flaperon system allows for more efficient control of the aircraft during descent.
• Engineers designed the flaperon to serve dual purposes in the experimental aircraft.
