Landing Gear 03

Question 1

Oil used in the oleo strut:

c.limits the speed of compression and extension of the strut

d.supports the weigh of the aircraft

Answer 1

c. limits the speed of compression and extension of the strut

Question 2

The nose wheel assembly must be centred before retraction because:

Answer 2

b. there is limited space in the nose undercarriage bay

Question 3

The movement of the gear during lowering is normally damped to:

a.make the lowering time greater than the raising time

b.prevent hyd fluid from becoming overheated

Answer 3

c. counteract the forces of gravity which would bring the gear down to fast

Question 4

Creep marks prevent creep

Select one:
True
False

Answer 4

False

Question 5

Creep (slippage)

a.refers to the movement of the aircraft against the brakes

b.is prevented by painting lines in the wheel and tyre

d.is a problem that is encountered on a tubeless tyre

Answer 5

c. can rip out the inflation valve on a tubed tyre and deflate the tyre

Question 6

Inadvertent retraction of the landing gear on the ground is:

a.prevented by the air/ground logic system

b.is the responsibility of the first officer

c.always a danger when the ground locks have been removed

d.is not possible because the system is not powerful enough

Answer 6

a. prevented by the air/ground logic system

Question 7

a.torque links

b.a shock absorber

c.down locks

d.an anti-skid braking system

Answer 7

Question 8

A nosewheel steering control system:

c.is selected by the first officer

d.allows the nose wheel to castor within preset limits about the neutral position

Answer 8

d. allows the nose wheel to castor within preset limits about the neutral position

Question 9

Landing ground lock pins are:

a.removed prior to flight and stowed in the aircraft

b.removed before flight and returned to stores

c.fitted before flight to ensure the landing gear locks are fully engaged

d.fitted after flight to maintain a hydraulic lock in the downlock jack

Answer 9

a. removed prior to flight and stowed in the aircraft

Question 10

When is the torque link under most stress:

a.on an rejected takeoff

b.during crosswind landings

c.when taking off

d.on the ground during tight turns using isometric thrust and braking

Answer 10

d. on the ground during tight turns using isometric thrust and braking

Question 11

The anti-skid system would be used:

a.on take-off only

b.for take-off on icy runways

c.on landing only

d.for both take-off and landing

Answer 11

d. for both take-off and landing

Question 12

At a aircraft taxiing speed of 10 mph the anti-skid braking system is:

a.operative

b.inoperative

c.operative only on the nose wheel brakes

d.operative only on the main wheel brakes

Answer 12

b. inoperative

Question 13

The most lightly cause of brake unit dragging is:

a.incorrect operation of the brake adjuster

b.dirt between the rotor and stator assemblies

c.grease on the rotor assembly

d.the brake pressure being to high

Answer 13

a. incorrect operation of the brake adjuster

Question 14

A likely cause of nose wheel shimmy is:

a.the aircraft is to heavy

b.the nosewheel tyres pressurises are to high

c.the nosewheel torque link is worn or damaged

d.the aircraft is incorrectly loaded

Answer 14

c. the nosewheel torque link is worn or damaged

Question 15

The ply rating of a tyre is:

a.an indication that the tyre must be fitted with an inner tube

b.the number of cords or plies in that tyre

c.the index of the tyre strength

d.the number of plies in that tyre

Answer 15

c. the index of the tyre strength

Question 16

The most likely cause of brake fade is:

a.the brakes overheating

b.oil or grease on the brake unit

c.the pilot reducing brake pressure

d.worn stators

Answer 16

a. the brakes overheating
