| Question | Answer |
|---|---|
| The primary purpose for balancing aircraft wheel assemblies is to: - - prevent heavy spots and reduce vibration. - - distribute the aircraft weight properly. - - reduce excessive wear and turbulence. | prevent heavy spots and reduce vibration |
| Power boost brake systems are used on aircraft that have: - - high landing speeds. - - low normal hydraulic system pressure. - - more than one brake assembly per axle. | high landing speeds |
| On all aircraft equipped with retractable landing gear, some means must be provided to: - - retract and extend the landing gear if the normal operating mechanism fails. - - extend the landing gear if the normal operating mechanism fails. - - prevent the throttle from being reduced below a safe power setting while the landing gear is retracted. | extend the landing gear if the normal operating mechanism fails |
| An automatic damping action occurs at the steering damper if for any reason the flow of high-pressure fluid is removed from the: - - outlet of the steering damper. - - inlet of the steering damper. - - replenishing check valve. | inlet of the steering damper |
| What is the purpose of the torque links attached to the cylinder and piston of a landing gear oleo strut? - - Limit compression stroke. - - Hold the strut in place.- - Maintain correct wheel alignment. | Maintain correct wheel alignment |
| The removal, installation, and repair of landing gear tires by the holder of a private pilot certificate on an aircraft owned or operated is considered to be? - - a violation of the Federal Aviation Regulations. - - a minor repair, - - preventive maintenance. | preventive maintenance |
| Aircraft brakes requiring a large volume of fluid to operate the brakes generally: - - use independent master cylinder systems. - - do not use brake system accumulators. - - use power brake control valves. | use power brake control valves |
| What is one effect a restricted compensator port of a master cylinder will have on a brake system? - - The brakes will operate normally. - - The reservoir will be filled by reverse flow. - - The restriction will cause slow release of the brakes. | The restriction will cause slow release of the brakes |
| When an air/oil type of landing gear shock strut is used, the initial shock of landing is cushioned by: - - compression of the air charge. - - the fluid being forced through a metered opening. - - compression of the fluid. | the fluid being forced through a metered opening |
| Internal leakage in a brake master cylinder unit can cause: - - fading brakes. - - slow release of brakes. - - the pedal to slowly creep down while pedal pressure is applied. | the pedal to slowly creep down while pedal pressure is applied |
| A sleeve, spacer, or bumper ring is incorporated in a landing gear oleo shock strut to: - - limit the extension of the torque arm. - - limit the extension stroke. - - reduce the rebound effect. | limit the extension stroke |
| The purpose of a sequence valve in a hydraulic retractable landing gear system is to: - - prevent heavy landing gear from falling too rapidly upon extension. - - provide a means of disconnecting the normal source of hydraulic power and connecting the emergency source of power. - - ensure operation of the landing gear and gear doors in the proper order. | ensure operation of the landing gear and gear doors in the proper order |
| The pressure source for power brakes is: - - the main hydraulic system. - - the power brake reservoir. - - a master cylinder. | the main hydraulic system |
| Which statement is true with respect to an aircraft equipped with hydraulically operated multiple disk type brake assemblies? - - There are no minimum or maximum disk clearance checks required due to the use of self-compensating cylinder assemblies. - - Do not set parking brake, when brakes are hot. - - No parking brake provisions are possible for this type of brake assembly. | Do not set parking brake, when brakes are hot |
| What type of valve is used in the brake actuating line to isolate the emergency brake system from the normal power brake control valve system? - - A bypass valve. - - An orifice check valve. - - A shuttle valve. | A shuttle valve |
| When servicing an air/oil shock strut with MIL-5606 the strut should be: - - collapsed and fluid added at the filler opening. - - fully extended and fluid added at the filler opening. - - partially extended and fluid added at the filler opening. | collapsed and fluid added at the filler opening |
| Instructions concerning the type of fluid and amount of air pressure to be put in a shock strut are found: - - on the airplane data plate. - - in the aircraft operations limitations. - - in the aircraft manufacturer's service manual. | in the aircraft manufacturer's service manual |
| The purpose of a relief valve in a brake system is to: - - reduce pressure for brake application. - - prevent the tire from skidding.- - compensate for thermal expansion. | compensate for thermal expansion |
| Aircraft tire pressure should be checked: - - using only a push on stick-type gauge having one-pound increments. - - at least once a week or more often. - - as soon as possible after each flight. | at least once a week or more often |
| If the extended longitudinal axis of the main landing gear wheel assemblies intersects aft of the aircraft, the wheels can be termed as having: - - toe-out. - - toe-in. - - negative camber. | toe-out |
