What is one purpose of wing flaps? A. To enable the pilot to make steeper approaches to a landing without increasing the airspeed. B. To relieve the pilot of maintaining continuous pressure on the controls. C. To decrease wing area to vary the lift. - ANSWER *A. To enable the pilot to make steeper approaches to a landing without increasing the airspeed.* -Extending the flaps increases the win camber and the angle of attack of the wing. This increases wing lift and induced drag, which enables the pilot to make steeper approaches to a landing without an increase in airspeed. One of the main functions of flaps during approach and landing is to A. decrease the angle of descent without increasing the airspeed. B. permit a touchdown at a higher indicated airspeed. C. increase the angle of descent without increasing the airspeed. - ANSWER *C. increase the angle of descent without increasing the airspeed.* -Extending the flaps increases the win camber and the angle of attack of the wing. This increases wing lift and induced drag, which enables the pilot to increase the angle of descent without increasing the airspeed. What is the purpose of the rudder on an airplane?
