1.	Why are flaps deflected downwards?(a) To decrease lift(b) To increase lift(c) To decrease the effective curvature of the wing(d) To increase the effective curvature of the wingThe question was posed to me in final exam.My question is based upon Flight Control-2 in portion Flight Dynamics and Control of Aircraft Maintenance
Answer» Right choice is (d) To increase the EFFECTIVE curvature of the wing Explanation: Flaps are deflected downwards to increase the effective curvature of the wing. Flaps are USED during descent or TAKE off. They are used to reduce stalling SPEED of an aircraft and are mostly used during LOW speed.
