Gear Tyres Brakes and Wheels

Question 1

The auto-brake system is disconnected during landing:

Answer 1

By pilot action

Question 2

If the profile grooves or the tread of a new aircraft tyre are worn, the tyre can be:

Answer 2

Repaired several times.

Question 3

The type of system where accomplishes steering by use of the rudder pedals?

Answer 3

Direct Rod Linkage

Question 4

To prevent tubeless tyres from blowing out from excessive pressure built op due to the generated heat fr0m taxiing and braking -

Answer 4

thermal fuse plugs are used

Question 5

The shoulder is the first area of the tyre -

Answer 5

after the crown

Question 6

Advantages of tubeless tyres:

1. saving in both _____ and ___ of tubes
2. No ____ generation from friction between ___ and ___
3. Reduced _______ from punctures. Unlike the tube in a tubed tyre the lining of a tubeless tyre is not stretched and to a degree will form a seal around the puncturing object
4. Tyre creep is of ___ significance

Answer 6

1. saving in both weight and cost of tubes
2. No heat generation from friction between tyre and tube
3. Reduced deflation from punctures. Unlike the tube in. a tubed tyre the lining of a tubeless tyre is not stretched and to a degree will form a seal around the puncturing object
4. Tyre creep is of less significance

Question 7

Which anti-skid type:

This anti-skid is mounted on the torque plate of the brake unit within the axle bore. It comprises a valve assembly connected to a flywheel driven by the aircraft wheel. The flywheel rotates at the same speed as the wheel during braking when no skid is present. A rapid decrease in wheel rotation, such as would occur just prior to a skid, results in the inertia of the flywheel opening a valve in hydraulic pressure line. This reduction in pressure corresponds to a decrease in braking force.

Answer 7

Mechanical Anti-skid system

Question 8

Which anti-skid type:

This system comprises skid control generators, a skid control box and skid control valves

Answer 8

Electronic anti-skid unit.

Question 9

The autobrakes comes into operation when -

Answer 9

gear up is selected

Question 10

The term autobrakes is also applied to systems in which brakes are applied -

Answer 10

immediately after touchdown, or during RTO(rejected take-off)

Question 11

When a landing gear wheel is hydroplaning, its friction factor is equal to:

Answer 11

0

Question 12

Another name for torque links?

Answer 12

Scissor links
