| REVIEW OF AERODYNAMIC TERMS - FLAPS | ||
The control surface that lowers from the back (or trailing edge) of the wing is the flap. Flaps are used in the takeoff and landing phases of flight to allow the aircraft to fly safer at slower speeds by actually changing the shape (camber) of the wing. When you are flying in a commercial aircraft during its approach to landing, you often hear the pilot actuating the flap motors to lower the flaps during the approach. Next time you fly, if you are sitting near one of the wings, look out the window and watch the flaps come down in increments during the approach. The pilot puts the flaps down more and more as the aircraft slows during its approach. |
