The purpose of an orifice check valve is to
restrict flow in one direction and allow free flow in the other.
A stripe or mark applied to a wheel rim and extending onto the sidewall of a tube-type tire is a
slippage mark.
Chines are used on some aircraft nose wheel tires to help
deflect water away from the fuselage.
Main indication / Symptom of Air in system in Brake system
Spongy Brakes
What controls the inflation sequence in a pneumatic deicer boot system?
Distributor Valve
What maintains normal windshield temperature control in an electrically heated windshield System ?
Thermisters
The fusible plugs installed in some aircraft wheels will
melt at a specified elevated temperature.
When bleeding aircraft brakes, one of the indications that the air has been purged from the system is
Firm Brake pedals
What is the purpose of the torque links attached to the cylinder and piston of a landing gear Oleo Strut ?
Maintain correct wheel alignment.
Arcing in an electrically heated windshield panel usually indicates a breakdown in the
conductive coating.
On an air valve core stem, what indicates high-pressure type?
HP stamped on valve
The purpose of a relief valve in a brake system is to
compensate for Thermal Expansion
The correct inflation pressure for an aircraft tire can be obtained from

Most common type of Hydraulic fluid in Shock Struts
Mil-5606
If an aircraft shock strut (air/oil type) bottoms upon initial landing contact, but functions correctly during taxi, the most probable cause is
Low Fluid
The pressure source for brakes on a 737
the main hydraulic system.
Internal leakage in a brake master cylinder unit can cause
the pedal to slowly creep down while pedal pressure is applied
What is a Boagie
When two wheels are attached to a beam on one strut, the attached mechanism is referred to as a bogie
What should be checked when a shock strut bottoms during a landing?
Fluid Low
An electric motor used to raise and lower a landing gear would most likely be a
shunt field series-wound motor.
In shock struts, chevron seals are used to
prevent oil from escaping.
What is the function of a cam incorporated in a nose gear shock strut?
Straightens the nosewheel.
The primary purpose for balancing aircraft wheel assemblies is to
prevent heavy spots and reduce vibration.

How long should you wait after a flight before checking tire pressure?
At least 2 hours (3 hours in hot weather).
