AMS 263 - Unit 3 Exam 2026 Questions
and Answers
If a brake debooster is used in a hydraulic brake system, its position in the system
will be - Correct answer-between the brake control valve and the brake actuating
cylinder.
To prevent a very rapid extension of an oleo shock strut after initial compression
resulting from landing impact, - Correct answer-various types of valves or orifices
are used which restrict the reverse fluid flow.
Lockout deboosters are primarily pressure reducing valves that - Correct answer-
allow full debooster piston travel without fluid from the high pressure side entering
the low pressure chamber.
Debooster cylinders are used in brake systems primarily to - Correct answer-reduce
the pressure to the brake and increase the volume of fluid flow.
When servicing an air/oil shock strut with MIL-5606 the strut should be - Correct
answer-collapsed and fluid added at the filler opening.

, If an airplane equipped with master cylinders and single-disk brakes has excessive
brake pedal travel, but the brakes are hard and effective, the probable cause is -
Correct answer-worn brake linings.
A hydraulic system referred to as a 'power pack' system will - Correct answer-have
all hydraulic power components located in one unit.
When an air/oil type of landing gear shock strut is used, the initial shock of landing
is cushioned by - Correct answer-the fluid being forced through a metered opening.
If the extended longitudinal axis of the main landing gear wheel assemblies
intersects aft of the aircraft, the wheels can be termed as having - Correct answer-
toe-out.
A filter incorporating specially treated cellulose paper is identified as a - Correct
answer-micronic filter.
A stripe or mark applied to a wheel rim and extending onto the sidewall of a tube-
type tire is a - Correct answer-slippage mark.
The left brake is dragging excessively on an airplane on which no recent brake
service work has been performed. The most probable cause is - Correct answer-
foreign particles stuck in the master cylinder compensating port.
