To Prevent a very rapid extension of an oleo strut after initial compression resulting from landing impact

Various Types of valves

Spongy brakes are caused by

air in the brake system

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

an indefinite number of times

Aircraft tire pressure should be checked

at least once a week or more often

The_____gives the tire the needed strength to assure a firm mounting on the wheel

bead

If the antiskid system malfunctions,the pilot can

dissable it without affecting normal braking

12. The purpose of a sequence valve in a hydraulic retractable landing gear is to

ensure operation of the landing gear and gear doors in the proper order

Aside from an external leak in the line,what will cause parking brakes to creep continuosly to the OFF position?

internal leak in the master cylinder or parking brake valve

After performing maintenance on an aircraft landing gear which may have afffected the system operation,it is usually necesary to

make an operational check with the aircraft on jacks

The fusible plugs installed in some aircraft wheels will

melt a a specified elevated temperature

releasing the air charge and seeing that the oil is to the level of the filler plug

The metering pins in oleo shock struts serve to

retard the flow of oil as the strut is compressed
