Question Number. 4. The bearing used in a fibre pulley is.
Option A. a ball bearing.
Option B. a roller bearing.
Option C. a plain bearing.



Question Number. 5. When the primary stops fitted to a control run have been contacted.
Option A. a clearance exists at the secondary stops.

Option A. excessive cable tension.
Option B. pulley misalignment.
Option C. cable misalignment.


Question Number. 7. A universal protractor used to measure degrees of aileron travel should be zeroed.
Option A. when the aircraft is in level flight attitude.
Option B. with the aileron in the neutral position.
