Airframe 3 landing gear/hyds
Exposure to and/or storage near which of the following is considered harmful to aircraft tires? 1. Low humidity. 2. Fuel. 3. Oil. 4. Ozone. 5. Helium. 6. Electrical equipment. 7. Hydraulic fluid. 8. Solvents.
2, 3, 4, 6, 7, 8.
What is the minimum amount of time to wait for tires to cool before checking tire pressure?
3 hours.
On an air valve core stem, what indicates high-pressure type?
An embossed letter 'H.'
How long should you wait after a flight before checking tire pressure?
At least 2 hours (3 hours in hot weather).
Why do most aircraft tire manufacturers recommend that the tubes in newly installed tires be first inflated, fully deflated, and then reinflated to the correct pressure?
To allow the tube to position itself correctly inside the tire.
When working with high pressure, high performance tires, why is it recommended to deflate the tires when removing wheels from the axle?
To ensure safety in case of a defective wheel or broken tie bolts.
Lockout deboosters are primarily pressure reducing valves that
allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber.
A high-speed aircraft tire with a sound cord body and bead may be recapped
an indefinite number of times.
The fusible plugs installed in some aircraft wheels will
melt at a specified elevated temperature.
Excessive wear in the center of the tread of an aircraft tire is an indication of
overinflation.
The primary purpose for balancing aircraft wheel assemblies is to
prevent heavy spots and reduce vibration.
The best safeguards against heat buildup in aircraft tires are
short ground rolls, slow taxi speeds, minimum braking, and proper tire inflation.
A stripe or mark applied to a wheel rim and extending onto the sidewall of a tube-type tire is a?
slippage mark.
A brake debooster valve is installed in systems where the high pressure of the hydraulic system (3000 psi) is used to operate brakes
that are designed to work with lower pressure.
The correct inflation pressure for an aircraft tire can be obtained from
the aircraft service manual.
The pressure source for power brakes is
the main hydraulic system.
A close inspection of a fusible plug reveals the core has experienced some deformation. What is the appropriate maintenance procedure?
Replace all the fusible plugs.
The left brake is dragging excessively on an airplane on which no recent brake service work has been performed. The most probable cause is
foreign particles stuck in the master cylinder compensating port.
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.
Overinflated aircraft tires may cause damage to the
wheel flange.
