12-9. Hydraulically actuated nosewheel steering systems are controlled by which of the following methods? Manually Electrically only Mechanically only Electrically or mechanically 12-10. In a nosewheel steering system, what component generates an electrical signal proportional to the amount of rudder pedal deflection? 1. The feedback potentiometer 2. The command potentiometer 3. The steering transducer 4. The steering amplifier 12-11. You are performing an operational check on the nosewheel steering system with the nose gear turned to 30° right of center. What action, if any, will occur when you extend the arresting gear? 1. It will return to the center position 2. It will move 1 inch right of center 3. It will move 1 inch left of center 4. None 12-12. When adjusting the nosewheel steering amplifier, which of the following procedures should you perform? 1. Operate the steering switch 2. Insert rigging pin No. 1 into the rudder pedal linkage 3. Check to see that the gear centers within 2° of center index mark 4. Each of the above 12-13. When the steering dampener assembly of a mechanically controlled nose steering system is sent to the intermediate level of maintenance, which of the following bench tests are performed with the unit in neutral while the return leakage is being measured? The no steer test The output torque test The stall leakage test The steering resolution test 12-14. During an aircraft landing gear drop check, what is the maximum (a) pressure and (b) gallons per minute of hydraulic fluid required to retract and lock the gear? (a) 1800 psi (b) 4 gpm (a) 2000 psi (b) 2 gpm (a) 2400 psi (b) 3 gpm (a) 3000 psi (b) 4 gpm 12-15. When you are performing an emergency extension of the landing gear during a drop check, the force required to push the main landing gear to the locked position at the axle hub should NOT exceed what maximum amount? 50 lb 20 lb 30 lb 40 lb 12-16. A significant number of unsafe or hung landing gear discrepancies are caused by which of the following maintenance related problems? 1. Improper rigging only 2. Improper adjustment of linkages only 3. Improper rigging or improper adjustment of linkages only 4. Improper rigging, improper adjustment of linkages, or factory defective parts 12-17. You can release the nitrogen pressure from a shock strut by which of the following means? Removing the valve core Depressing the valve core Turning the valve swivel nut clockwise Turning the valve swivel nut counterclockwise 12-18. When removing a shock strut from an aircraft, you should remove the wheel and brake assembly to reduce the weight and allow for easier handling. True False 12-19. To ensure complete compression when deflating a typical shock strut, you may need to perform which of the following functions? Rock the aircraft Hoist the aircraft Lower the arresting gear Bleed the landing gear accumulator 61
