Q

What is the function of the priority valve on system 3?

A

To give priority to the FLIGHT CONTROLS and INBOARD BRAKES

17
Q

What do the L&R HEAT lights indicate?

A

Sufficient heat for wing anti-ice (29c)

18
Q

What changes when the WSHLD switches are set from LOW to HIGH?

A

The windshields go HIGH; the windows remain LOW.

19
Q

What happens to the wing and cowl anti-ice during T/R operation? Why?

A
  • ANTI-ICE functions are inhibited

- 14 stage bleed air gives priority to the T/R.

20
Q

What is the FAIL SAFE MODE of the ADSHCs?

A

ON

21
Q

What does ADSHC mean?

A

Air Data Sensor Heat Controler

22
Q

How does the wing anti-ice system operate in NORMAL and STANDBY mode?

A
  • NORMAL mode regulates valves to maintain L.E. temp (88c)

- STANDBY mode valves fully OPEN or CLOSED the temp varies (49c-82c)

23
Q

How doe the ice detector work and what is the heating cycle?

A
  • Ice accumulation changes the probe’s vibration freq

- 5 seconds of heat followed by 55 seconds of no heat

24
Q

Where are the ANTI-ICE DUCTS located?

A

Aft equipment bay; under the cabin; along the wings.

25
Q

What sensor triggers a “WING OVERHEAT” warning?

A

SUFFICIENT HEAT/OVERHEAT SENSOR (end of wing leading edge)

26
Q

14th stage bleed valves fail ________________?

A

Open

27
Q

How is a bleed air leak detected on the wings?

A

There are 38 total heat detection switches on the backside of the wing bleed ducts.

28
Q

What is the purpose of the SUPPLEMENTARY GROUND ANTI-ICE system?

A

To provide adequate anti-icing during ground operations without hearing the wing to high enough values to “bake” the anti-ice fluid to the wing.

This is useful for taxiing to position to abound ground ice accumulation before taking the active.

29
Q

How warm are the windows/windshields in LOW mode?

A

Windshields 41c

Windows 41c

30
Q

How warm are the windows/windshields in high mode?

A

Windshields 58c

Windows 41c

31
Q

What must be on for the L(R) Probes to work?

A

An engine driven generator

32
Q

Which hydraulic system does the ADG power?

A

3B only

33
Q

What does AUTO switch selection do?

A

Activates hydraulic pumps when flaps are beyond 4-8 degrees.

34
Q

What is on the #1 hydraulic system?

A

GREAF

  • GRND SPOLIERS
  • RUDDER
  • ELEVATOR(L)
  • AILERON(L)
  • FLT SPOLIERS
35
Q

When do hydraulic pressure indications turn amber?

A

At 1799 psi

36
Q

At what quantity do the hydraulic quantity indicators turn white?

A

45%

37
Q

What is on the #3 hydraulic system?

A

LEARNIN

  • LDG GEAR
  • ELEVATOR (L/R)
  • AILERON (L/R)
  • RUDDER
  • NOSE DOOR
  • INBOARD BRAKES
  • N/W STEERING
38
Q

What is on the #2 hydraulic system?

A

FRAME-O

  • FLT SPLR
  • RUDDER(R)
  • AILERON(R)
  • MLG AUX ACT
  • ELEVATOR(R)
  • OUTBOARD BRAKES
39
Q

When doing walk-around what pressure are we looking for in the nitrogen accumulator?

A

1450-1550 psi
