ABOVE QUESTIONS WITH ANSWERS 

Question Number. 11. On the ground, spoilers/speedbrakes deploy to.
Option A. 15°.
Option B. 30°.
Option C. 60°.
Correct Answer is. 60°.
Explanation. Transport Category Aircraft Systems Jeppesen Page 5-6. In the air - 30 degrees and a further 15 degrees with ailerons.


Question Number. 12. A horn balance on a control will.
Option A. increase degree of movement at high speed.
Option B. decrease degree of movement at low speed.
Option C. decrease degree of movement at high speed.
Correct Answer is. increase degree of movement at high speed.
Explanation. For a given pilot effort, the horn balance increases movement.


Question Number. 13. In normal flight, if the control column is pulled back, a servo tab fitted to the elevator will.
Option A. move up.
Option B. remain in line with the elevator.
Option C. move down.
Correct Answer is. move down.
Explanation. NIL.


Question Number. 14. In normal flight, if the control wheel is moved to the left, then the aileron on the right wing will.
Option A. decrease the angle of attack of the right hand wing.
Option B. increase the angle of attack of the right hand wing.
Option C. keep the angle of attack of the right wing constant.
Correct Answer is. increase the angle of attack of the right hand wing.
Explanation. Could also be answered 'b', depending on whether it means the cause or the effect. The downgoing aileron (the right one) has an increase in AoA locally, which makes the wing lift, thusreducing the AoA of the wing as a whole. Choose your interpretation.


Question Number. 15. On an aircraft fitted with elevons in normal flight, if a column is moved forward, the elevons will.
Option A. remain stationary.
Option B. both move down.
Option C. both move up.
Correct Answer is. both move down.
Explanation. NIL.


Question Number. 16. To avoid moments bending the root of the wing, the aircraft will be fitted with.
Option A. integrated fuel monitoring system.
Option B. symmetrical flight control trim.
Option C. automatic trim control for controlled turns and rudder movements.
Correct Answer is. symmetrical flight control trim.
Explanation. Probably referring to Load Alleviation Function. Jeppesen Transport Category Aircraft Systems Page 5-29.


Question Number. 17. A yaw damper gain could be fitted with.
Option A. decreases sensitivity for decreased speed.
Option B. increased sensitivity for increased speed.
Option C. decreases sensitivity for increased speed.
Correct Answer is. increased sensitivity for increased speed.
Explanation. Automatic Flight Control, Pallett Page 223.


Question Number. 18. In an aircraft system employing balance tabs, the installation of external ground locks between the control surface and the balance tabs.
Option A. would prevent the movement of the control column.
Option B. is unnecessary since the system is irreversible.
Option C. would not prevent the movement of the control column.
Correct Answer is. would prevent the movement of the control column.
Explanation. A+P Technician Airframe Textbook Page 1-29.


Question Number. 19. The two switches for pitch trim are located.
Option A. on the control column acting like an 'AND' switch.
Option B. on the control column with the captain having priority over the First Officer.
Option C. on the control column acting like an 'OR' switch.
Correct Answer is. on the control column acting like an 'AND' switch.
Explanation. The 'split' trim switch has one half closing a relay to 'enable' power to the trim motor, and to engage the clutch. The other switch half is to supply the power to the motor. Both must be operated together, to operate the trim.


Question Number. 20. If the flaps are sluggish or erratic on final approach, the possible cause may be.
Option A. flap tracks out of rigging.
Option B. bearing seized.
Option C. flap motor internal leakage.
Correct Answer is. flap motor internal leakage.
