21
Q

Antiskid protection is provided in the ___/___ and _____ brake hydraulic systems.

A

normal/reserve, alternate

22
Q

BRAKE SOURCE. Þýðir þetta að normal og/eða alternate brake system pressure er lágt?

A

Já bæði normal og alternate (reyndar laterally paired)

23
Q

Hvernig virka reserve brakes

A

Í raun er þetta bara normal brakes nema tekur reserve hydraulic fluid og setur það BARA í normal brakes. Takmarkað hvað þú getur bremsað mikið geri ég ráð fyrir.

24
Q

An initial pre-charge is shown by the amber band (____ psi) on the indicator. A reading at or below the amber band indicates no Brake Accumulator pressure is available.

A

1300

25
Q

The alternate brake hydraulic system provides antiskid protection to laterally ____ wheels.

A

paired

26
Q

The alternate brake hydraulic system provides antiskid protection to laterally ____ wheels.

A

paired

27
Q

Antiskid gives no protection below ___ kts.

A

7.5

28
Q

Runway condition code RCC er 5 eða 6, hvaða autobrake þarftu?

A

Engar

29
Q

Hvaða autobrakes notar þú í routine operations?

A

1 eða 2

30
Q

Hvaða autobrake notar þú í routine ops, low vis og degraded braking action?

A

3

31
Q

Hvaða autobrake notar þú ef þú hefur short runway, low vis, degraded braking action

A
  1. Key orðið er short runway en annars hefðir þú getað tekið autobrake 3 við sömu skilyrði.
32
Q

Hvaða autobrake notar þú ef maximum stopping er required?

A

MAX, myndir samt ná meiri bremsun með full manual braking.

33
Q

After landing, autobrake application begins when… (2)

A

– both thrust levers are retarded to idle, and
– the wheels have spun up

34
Q

Geturðu breytt autobrake í miðjum leik?

A

Já

35
Q

Autobrake application occurs slightly after..

A

main gear touchdown.

36
Q

True eða false; Setting the parking brake is mechanically possible without any hydraulic pressure at all.

A

True

37
Q

What powers the landing gear extension and
retraction during normal operation?
A. The Right hydraulic system
B. The Left hydraulic system
C. The Center hydraulic system
D. The Right and Left hydraulic system

A

B. The Left hydraulic system

38
Q

What powers the landing gear down during
alternate gear extension?
A. The Right hydraulic system
B. The Left hydraulic system
C. The Center hydraulic system
D. Gravity

A

D. Gravity

39
Q

Aircraft on ground. The accumulator pressure
is in the amber band. This means:
A. The hydraulic pressure in the accumulator
is rather low
B. No parkbrake is available
C. Nothing
D. Park brake is available but the
accumulator should be serviced

A

B. No parkbrake is available

40
Q

What does the message „BRAKE SOURCE“
indicate?
A. The brakes are inop
B. Both the normal and the alternate brake
system pressures are low.
C. The normal brake system pressure is low
D. The alternate brake system pressure is
low

A

B. Both the normal and the alternate brake
system pressures are low.

41
Q

What is accomplished by pushing the „reserve
brakes“ switch
A. It provides reserve hydraulic fluid to the
right system electric pump. Pump pressure
is then supplied exclusively to the normal
brakes system
B. The reserve brake system is activated
C. Standpipe hydraulic fluid from the left
system is used to power the alternate
brake system
D. Pushing the switch does not accomplish
anything

A

A. It provides reserve hydraulic fluid to the
right system electric pump. Pump pressure
is then supplied exclusively to the normal
brakes system

42
Q

What message appears when the parkbrake
valve does not open when the parkbrake is
released?
A. „Brake valve“
B. „Parking brake valve“
C. „Antiskid“
D. No message

A

C. „Antiskid“

43
Q

What is true regarding the autobrake system?
A. RTO provides the same braking power as
Max AUTO
B. RTO provides the same braking power as
Max Manual
C. RTO arms above 85 kts groundspeed
D. Both B and C are correct

A

D. Both B and C are correct.

44
Q

The Takeoff configuration warning includes:
A. Trim and flaps
B. Trim, flaps, park brake, spoilers
C. Trim, flaps, park brake
D. Trim, flaps, park brake, spoilers, engine
parmeters

A

B. Trim, flaps, park brake, spoilers

45
Q

RTO initiated at 100 kts durning t/o in KEF.
Takeoff weight is 95.0T. Temperature is
0°C. Max manual braking with full reverse
thrust. What is the brake cooling time?
a) In the caution zone so takeoff has to be
delayed
b) In the fuse plug melt zone
c) 66 min
d) 36 min

A

d) 36 min

46
Q

When will the AUTO BRAKES light be
illuminated?
a) When the selector is in the DISARM
position.
b) When the selector is in the OFF
position.
c) When the auto brakes system is
operating.

A

a) When the selector is in the DISARM
position.

47
Q

When does the alternate brake system
operate?
a) When right hydraulic pressure to
normal brakes is low.
b) When the antiskid controller detects a
fault in the normal brakes.
c) When the MAX AUTO setting is
selected for autobrakes.

A

a) When right hydraulic pressure to
normal brakes is low.

48
Q

When will the landing gear lever lock
release?
