ANSWERS


Question Number. 21. In fully Fly By Wire aircraft, wing root bending moments are reduced by.
Option A. transfer of fuel from one wing tank to another.
Option B. operation of the elevator.
Option C. symmetrical application of ailerons.
Correct Answer is. symmetrical application of ailerons.
Explanation. CAIPs EEL/1-2.


Question Number. 22. Yaw damping rate changes with.
Option A. airspeed.
Option B. flap position.
Option C. altitude.
Correct Answer is. airspeed.
Explanation. Avionic Fundamentals page 292.


Question Number. 23. What is the main purpose of a frize aileron?.
Option A. Decrease drag on the up going wing.
Option B. Help pilot overcome aerodynamic loads.
Option C. Increase drag on the up going wing.
Correct Answer is. Decrease drag on the up going wing.
Explanation. The Frise aileron increases drag on the up-going aileron, which is on the downgoing wing. And Vise versa on the other aileron.


Question Number. 24. What happens to a hydraulically operated flight control surface when pressure is removed?.
Option A. Droop.
Option B. Remain in last position.
Option C. Go to neutral.
Correct Answer is. Droop.
Explanation. "The drop in pressure releases a valve which lets the fluid pass easily from one side of actuator piston to the
other. This is to prevent a hydraulic lock and permit manual reversion. Surfaces behave like manually controlled surfaces."

Question Number. 25. Oscillation and hunting of flight control surface are prevented by.
Option A. fitting a tachogenerator.
Option B. feedback from the servo motor.
Option C. feedback from control surface.
Correct Answer is. fitting a tachogenerator.
Explanation. Automatic Flight Control by E.H.J.Pallett 3rd edition, page-157 (feedback, para 2).
Question Number. 26. Stick shaker activates at a speed which is above the stalling speed by.
Option A. 4%.
Option B. 7%.
Option C. 10.321%.
Correct Answer is. 7%.
Explanation. Aircraft Electricity and Electronics, Eismin 5th Edition Page-370.


Question Number. 27. A wing mounted stall warning vane.
