Chapter 8: Landing Gear Systems

Question 1

Chines are used on some aircraft nose wheel tires to help

Answer 1

C- deflect water away from the fuselage.

Question 2

Instructions concerning the type of fluid and amount of air pressure to be put in a shock strut are found

Answer 2

C- in the aircraft manufacturer’s service manual.

Question 3

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

Answer 3

C- firm brake pedals.

Question 4

What would be the effect if the piston return spring broke in a brake master cylinder?

Answer 4

C- The brakes would drag.

Question 5

A close inspection of a fusible plug reveals the core has experienced some deformation. What is the appropriate maintenance procedure?

Answer 5

A- Replace all the fusible plugs.

Question 6

A hydraulic system referred to as a ‘power pack’ system will

Answer 6

B- have all hydraulic power components located in one unit.

Question 7

Power boost brake systems are used on aircraft that have

Answer 7

A- high landing speeds.

Question 8

A fully charged hydraulic accumulator provides

Answer 8

B- a source for additional hydraulic power when heavy demands are placed on the system.

Question 9

What is the purpose of a compensating port or valve in a brake master cylinder of an independent brake system?

Answer 9

A- Permits the fluid to flow toward or away from the reservoir as temperature changes.

Question 10

Extension of an oleo shock strut is measured to determine the

Answer 10

C- proper operating position of the strut.

Question 11

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?

Answer 11

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

Question 12

What is the minimum amount of time to wait for tires to cool before checking tire pressure?

Answer 12

A- 3 hours.

Question 13

A pilot reports that the brake pedals have excessive travel. A probable cause is

Answer 13

B- lack of fluid in the brake system.

Question 14

Debooster valves are used in brake systems primarily to

Answer 14

C- reduce the pressure and release the brakes rapidly.

Question 15

What type of valve is used in the brake actuating line to isolate the emergency brake system from the normal power brake control valve system?

Answer 15

C- A shuttle valve.

Question 16

An automatic damping action occurs at the steering damper if for any reason the flow of high-pressure fluid is removed from the

Answer 16

B- inlet of the steering damper.

Question 17

The hydraulic packing seals used in a landing gear shock strut are

Answer 17

C- used only with a specific type of fluid.

Question 18

How is it determined in a master cylinder brake system that all of the air has been purged from the system?

Answer 18

B- By depressing the brake and noting that the brake is firm and not spongy.

Question 19

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

Answer 19

C- strut should be removed, disassembled, and inspected.

Question 20

Internal leakage in a brake master cylinder unit can cause

Answer 20

C- the pedal to slowly creep down while pedal pressure is applied.

Question 21

If an aircraft shock strut (air/oil type) bottoms upon initial landing contact, but functions correctly during taxi, the most probable cause is

Answer 21

A- low fluid.

Question 22

Overinflated aircraft tires may cause damage to the

Answer 22

C- wheel flange.

Question 23

The correct inflation pressure for an aircraft tire can be obtained from

Answer 23

B- the aircraft service manual.
