AIRCRAFT LANDING GEAR SYSTEM (continuation)

When a properly operating fusible plug has allowed a tire to deflate, the tire should be:

Replaced.

Externally inspected for damage.

Removed from the wheel and inspected for carcass and tread damage.

If it is determined that spongy brake action is not caused by air in the brake system, what is the next most likely cause?

Worn brake lining.

Internal leakage in the master cylinder.

Deteriorated flexible hoses.

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.

Low air charge.

A restricted metering pin orifice.

On most aircraft, the oil level of an air and oil shock strut is check by:

Removing the oil filler plug and inserting a gauge.

Measuring the length of the strut extension with a certain air pressure in the strut. INCE Te

Releasing the air and seeing that the oil is the level of the filler plug.

The braking action of a Cleveland disk brake is accomplished by compressing a rotating brake disk between two opposite brake linings. How is equal pressure on both sides of the rotating disk assured?

By allowing the brake rotor to float to automatically equalize as pressure is applied to the rotor.

By allowing the caliper to float to automatically equalize as pressure is applied to the rotor.

By allowing the brake linings to automatically equalize as pressure is applied to the rotor.

If a shock strut bottoms after it has been properly serviced, the

Strut should be disassembled and the metering pin orifice plate replaced.

Air pressure should be increased.

Strut should be removed, disassembled, and inspected.

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.

The pressure source for power brakes is:

The main hydraulic system.

The power brake reservoir.

A master cylinder.

A high-speed aircraft tire with a sound cord body and bead may be recapped

A maximum of three times.

Only by the tire manufacturer.

An indefinite number of times.

When an air/oil type of landing gear shock strut is used, the initial shock of landing shock of landing is cushioned by:

Compression of the air charge.

The fluid being forced through a metered opening.

Compression of the fluid.

O prevent a very rapid extension of an oleo shock strut after initial compression resulting from landing impact,

Various types of valves or orifices are used which restrict the reverse fluid flow.

The metering pin gradually reduces the size of the orifice as the shock strut extends.

The air is forced through a restricted orifice in the reverse direction.

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 connection the emergency source of power.

Ensure the operation of the landing gear and gear doors in the proper order.

When bleeding aircraft brakes, one of the indications that the air has been purged from the system is:

Partial brake pedal travel.

Full brake pedal travel.

Firm brake pedals.

The fusible plugs installed in some aircraft wheels will:

Indicate tire tread separation.

Prevent over inflation.

Melt at a specified elevated temperature.
