| Airplanes turn while remaining aloft primarily by controlling the positions of ailerons mounted on horizontally oriented wings. |
| Eva Air landed in Los Angeles in one piece, with rudder, elevator, fuselage, trim tabs and ailerons intact. |
| Such things as the wing tips, ailerons, trimming tabs, elevator, seats, berths and landing gear may be exchanged between one plane and another. |
| The other intuitive reaction is to attempt to roll the aircraft with ailerons to level the wings. |
| Avoid adverse yaw by allowing the ailerons to streamline when there's no crosswind present. |
| The aircraft also have composite ailerons, spoilers, flaps, vertical tail skin and horizontal tail skin, but they have aluminum wings. |
