Q1. The purpose of pulley wheels in cable control systems is:
Correct answer is – to change the direction of the control cable
Q2. The purpose of the primary stops in a control system is:
Correct answer is – to set the range of movement of the control surface
Q3. The purpose of the secondary stops in a control system is:
Correct answer is – to limit control surface range in the event of primary stop failure
Q4. The purpose of the fairleads in a cable control system is to:
Correct answer is – to keep the cable straight and clear of structure
Q5. In a cable control system cables are tensioned to: 1. remove backlash from the control linkage 2. provide tension on the turnbuckles 3. provide positive action in both directions 4. ensure the full range is achieved 5. compensate for temperature variations
Correct answer is – 1, 3 and 5 only
Q6. In a cable control system the cables are mounted in pairs to: 1. remove backlash from the control linkage 2. provide tension on the turnbuckles 3. provide positive action in both directions 4. ensure the full range is achieved 5. compensate for temperature variations
Correct answer is – 3 only
Q7. In a manual flying control system the control inputs to the primary control surfaces: 1. are reversible 2. are irreversible 3. are instinctive for the movement required 4. are opposite for the movement required 5. are limited in range by flight deck obstructions
Correct answer is – 1 and 3 only
Q8. To yaw the aircraft to the right:
Correct answer is – the right rudder pedal is pushed forward and the rudder moves to the right
Q9. To roll the aircraft to the right:
Correct answer is – the aileron control is moved to the right, the right aileron goes up and the left one down
Q10. The advantages of a cable control are: 1. light, very good strength to weight ratio 2. easy to route through the aircraft 3. less prone to impact damage 4. takes up less volume 5. less bolted joints
Correct answer is – all the above
