Q

What happens when you pull the fire EXTG handle?

A
  1. Closes Eng bleed air valve
  2. Closes fuel shut off valve
  3. Closes hydraulic shut off valve
  4. Generator line contactor will open as engine decelerates
19
Q

What happens when you press the APU guarded pushbutton?

A
  1. Closes APU shutoff valve

2. Discharges APU fire bottle

20
Q

In the event of an APU fire, will the bottle automatically discharge?

A

No

21
Q

Can we leave the airplane running unattended with the APU running?

A

No. Someone must be available to discharge the APU fire bottle

22
Q

Smoke detected on ground. What happens when the FWD CARGO SMOKE button is pushed?

A

1st push discharges HIGH rate bottle

2nd push required to discharge LOW rate bottle

23
Q

Smoke detected in flight. What would be different if we were in flight regarding the FWD CARGO SMOKE pushbutton?

A

1 st push discharges HIGH rate bottle

60 sec later LOW rate automatically discharges

24
Q

What happens to electrical power during a normal APU shutdown?

A

If APU is ONLY source of AC power…
-APU electrics will be available during cool down. (1 min)
If any other source of AC is available…
-APU electrics are removed right away

25
Q

What happens when the EMER STOP (guarded) button is pushed IN?

A

Closes the APU fuel shut off valve,
Shuts down APU without a 1 min cooldown
Illuminates white stripe on lower half of button

26
Q

In AUTO what will cause the PTU to operate?

A

Low pressure in system 2

  • A failure of ENG 2 or
  • A failure of ENG 2 EDP

(Assists with landing gear extension or retraction when there is Eng 2 failure or loss of EDP 2.)

27
Q

What is the PTUs primary purpose?

A

Provides normal gear retraction or extension in the event of eng 2 failure or EDP failure

28
Q

When will hydraulic system 1 ELEC (hyd) PUMP run automatically on ground?

A

During takeoff

Flaps > 0 and
Thrust levers advanced (60 deg)

Or

Ground speed >50kts

29
Q

When will hydraulic system 2 (hyd) pump run automatically?

A 
During takeoff
Flaps >0 and 
Thrust levers advanced (60 deg)
Or 
Ground speed >50kts 
AND
For single engine taxi...
-when eng 1 has been started and PRKG brake released
30
Q

In flight when will hyd SYS 1 or SYS 2 ELEC PUMP operate automatically?

A

If low press is detected

Or
Landing:
Flaps not at zero

31
Q

In AUTO when will hyd SYS 3 ELEC PUMP B turn on?

A

In flight when low pressure is detected

32
Q

When would the LFE CTRL pressurization mode be used?

A

If FMS is inop

Landing at an airport not in the FMS database

33
Q

With the pressurization mode in AUTO, what is the effect of pressing the DUMP button?

A

Turns off both packs and recirc fans, allowing aircraft to depressurize AND
Outflow valve modulates to raise cabin to 12400’ at 2000 FPM (natural leak will raise cabin higher)

34
Q

Windshield heating buttons are pushed in (automatic operation) PBIT is complete. You are on the ground. When will the windshield heaters operate?

A

With TWO sources of AC power, not counting the GPU

35
Q

You are in flight. What happens if ICE PROTECTION MODE knob is set to ON?

A

Overrides system logic and activates anti ice system regardless of icing condition

36
Q

What’s different if you’re on the ground and select ICE PROTECTION MODE to ON?

A

It only activates the engine anti-ice

37
Q

In flight what is the pneumatic bleed source priority for packs and wing anti ice?

A
  1. Respective side bleed
  2. Opposite side bleed
  3. APU bleed
38
Q

On ground if engine and APU bleed are available simultaneously, which has priority for engine start?

A

APU bleed

39
Q

What conditions command the RECIRC fans to the. Off automatically?

A
  1. Both packs are commanded OFF
  2. DUMP function button IN
  3. Smoke is detected in the recirculation bay.
40
Q

What conditions command the PACKS to turn off automatically?

A

DUMP button
Thrust levers MAX
During takeoff with REF ECS OFF and APU BLEED is unavailable

41
Q

What does the illumination of an amber striped bar in the upper half of a bleed button indicate?

A

An engine bleed leak

42
Q

When will passenger o2 masks automatically deploy?

A

Cabin pressure exceeds 14k

43
Q

What is the function of the TIMER position on the windshield wiper panel?

A

Provides intermittent operation
