landing gear

Question 1

what absorbs the taxi shocks in an oleo shock strut

Answer 1

the compressed air or nitrogen

Question 2

how much air or nitrogen should be put into an oleo shock strut

Answer 2

with the strut serviced with fluid and the filter plug in place and the weight of the aircraft on the strut, put in enough air or nitrogen to extend the piston to the height specified in the aircraft maintenance manualw

Question 3

what is the purpose of using an exerciser jack when servicing a shock strut with fluid

Answer 3

the jack moves the piston up and down inside the cylinder to work all of the air out of the oil to be sure that the proper amount of oil is in the strut

Question 4

what is a squat switch and where is it located

Answer 4

a landing gear safety switch the energizes a circuit to prevent the landing gear retraction handle from being moved to the retract position when weight is on the landing gear it is located in the torsion links of one of the main landing gears

Question 5

what kind of device is normally used as a sensor to detect the condition of a retractable landing gear

Answer 5

a precision microswitch

Question 6

what is the purpose of the centering cam in a nose wheel shock strut

Answer 6

the centering cam forces the nose wheel straight back when the strut before it is retracted into the nose wheel well

Question 7

what absorbs the initial landing impact in an oleo shock strut

Answer 7

the transfer of oil from one compartment to another through a metered orifice

Question 8

how should new aircraft tires be stored

Answer 8

in a dark, cool location away from electrical motors or battery chargers

Question 9

is it best to store new tires vertically or horizontally

Answer 9

vertically

Question 10

Answer 10

keep them properly inflated

Question 11

what should be used to remove oil from a tire

Answer 11

mild soap and warm water

Question 12

where do you find the proper inflation pressure for an aircraft tire

Answer 12

in the aircraft service manual

Question 13

why should aircraft tire pressure be rechecked after it has been installed for about 24 hours with no load applied

Answer 13

the tire will stretch and the pressure will drop the proper pressure must be restored

Question 14

what causes and aircraft tire to wear more on the shoulders than in the center of the tread

Answer 14

operating the tire in underinfated condition

Question 15

what causes and aircraft tire to wear more on the center of the tread than on the shoulders

Answer 15

operating the tire in an overinflated contidion

Question 16

what should be done to an aircraft tire if the sidewalls are weather checked enough to expose the cord

Answer 16

the tire should be scrapped

Question 17

what should be done with a tire that was on the wheel which was overheated enough to melt the fusible plug in the wheel

Answer 17

the tire should be scrapped

Question 18

Answer 18

A. an independent system not part of the aircraft main hydraulic system
B. a booster system that uses the aircraft hydraulic system intermittently
C. a power brake system that only uses the aircraft main hydraulic system as a source of pressure
