Extending the flaps increases the wing 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. Answer (B) is incorrect. Trim tabs (not wing flaps) help relieve control pressures. Answer (C) is incorrect. Wing area usually remains the same, except for certain specialized flaps that increase (not decrease) the wing area.
To relieve the pilot of maintaining continuous pressure on the controls
To decrease wing area to vary the lift
To enable the pilot to make steeper approaches to a landing without increasing the airspeed
Extending the flaps increase the wing 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. Answer (A) is incorrect. Extending the flaps increases lift and induced drag, which enables the pilot to increase (not decrease) the angle of descent without increasing the airspeed. Answer (B) is incorrect. Flaps increase lift at slow airspeed, which permits touchdown at a lower (not higher) indicated airspeed.
increase the angle of descent without increasing the airspeed.
decrease the angle of descent without increasing the airspeed.
permit a touchdown at a higher indicated airspeed
To control overbanking tendency
To control yaw
To control roll
The three primary flight controls of an airplane are the ailerons, the elevator (or stabilator), and the rudder. Answer (B) is incorrect. The stabilator, or elevator, is a primary flight control. Answer (C) is incorrect. Ailerons are a primary flight control surface.
The elevator is the primary control device for changing the pitch attitude of an airplane about the lateral axis. Answer (A) is incorrect. Ailerons are control surfaces attached to each wing that move in the opposite direction from one another to control roll about the longitudinal axis. Vertical is incorrect. The rudder controls movement of ht aircraft about its vertical axis.
Only when all three primary flight controls move in sequence do the airflow and pressure distribution change over and around the airfoil.
Primary flight controls include ailerons, rudder, elevator, and trim systems
The effectiveness of each control surface increases with speed because there is more airflow over them.
Flaps are attached to the leading edge of the wing and are used to increase wing lift
Flaps are high drag devices deployed from the wing to reduce lift
Flaps allow an increase in the angle of descent without increasing airspeed
