Q

What happens when you pull the fire EXTG handle?

Study These Flashcards
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?

Study These Flashcards
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?

21
Q

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

Study These Flashcards
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?

Study These Flashcards
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?

Study These Flashcards
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?

Study These Flashcards
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
What happens when the EMER STOP (guarded) button is pushed IN?
Closes the APU fuel shut off valve, Shuts down APU without a 1 min cooldown Illuminates white stripe on lower half of button
26
In AUTO what will cause the PTU to operate?
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
What is the PTUs primary purpose?
Provides normal gear retraction or extension in the event of eng 2 failure or EDP failure
28
When will hydraulic system 1 ELEC (hyd) PUMP run automatically on ground?
During takeoff Flaps > 0 and Thrust levers advanced (60 deg) Or Ground speed >50kts
29
When will hydraulic system 2 (hyd) pump run automatically?
``` 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
In flight when will hyd SYS 1 or SYS 2 ELEC PUMP operate automatically?
If low press is detected Or Landing: Flaps not at zero
31
In AUTO when will hyd SYS 3 ELEC PUMP B turn on?
In flight when low pressure is detected
32
When would the LFE CTRL pressurization mode be used?
If FMS is inop | Landing at an airport not in the FMS database
33
With the pressurization mode in AUTO, what is the effect of pressing the DUMP button?
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
Windshield heating buttons are pushed in (automatic operation) PBIT is complete. You are on the ground. When will the windshield heaters operate?
With TWO sources of AC power, not counting the GPU
35
You are in flight. What happens if ICE PROTECTION MODE knob is set to ON?
Overrides system logic and activates anti ice system regardless of icing condition
36
What's different if you're on the ground and select ICE PROTECTION MODE to ON?
It only activates the engine anti-ice
37
In flight what is the pneumatic bleed source priority for packs and wing anti ice?
1. Respective side bleed 2. Opposite side bleed 3. APU bleed
38
On ground if engine and APU bleed are available simultaneously, which has priority for engine start?
APU bleed
39
What conditions command the RECIRC fans to the. Off automatically?
1. Both packs are commanded OFF 2. DUMP function button IN 3. Smoke is detected in the recirculation bay.
40
What conditions command the PACKS to turn off automatically?
DUMP button Thrust levers MAX During takeoff with REF ECS OFF and APU BLEED is unavailable
41
What does the illumination of an amber striped bar in the upper half of a bleed button indicate?
An engine bleed leak
42
When will passenger o2 masks automatically deploy?
Cabin pressure exceeds 14k
43
What is the function of the TIMER position on the windshield wiper panel?
Provides intermittent operation
