AC BUS TIE

5
Q

What is the AC BUS TIE source priority?

A

APU
GPU
IDG

6
Q

What occurs if OFF is selected on IDG 1?

A

Opens the IDG contactor

Isolates IDG from respective bus

7
Q

What does the illumination of the amber LED indicate?

A

Which IDG to disconnect

Associated with IDG OIL caution EICAS

8
Q

If an IDG has been disconnected, can it be reconnected in flight?

A

No

9
Q

When will the AVAIL light illuminate?

A

When the GPU is connected but is NOT powering the AC BUS TIE (button can be in or out)

10
Q

When will “in use” illuminate?

A

When GPU is powering the AC BUS TIE (button must be pushed in)

11
Q

What happens if TRU (Transfer Relay Unit) switch is moved to OFF?

A

Isolated respective TRU from its associated D.C. BUS

12
Q

What is the difference between OFF and ON for BATT 1?

A

OFF supplies power to the HOT BATT BUS 1 only

ON connects battery to D.C. ESSENTIAL BUS 1

13
Q

What happens when BATT 2 is placed in the AUTO position?

A

Connects battery either to the DC ESS BUS 2 or the APU START BUS automatically, according to system logic

14
Q

What happens when XFEED is set to LOW 1

A

Opens cross feed valve
Activates AC PUMP 2
Supplies fuel to both engines from the right wing tank

15
Q

When will AC (fuel) PUMP 2 activate automatically?

A
  1. When ejector pump output is insufficient
    - eng start or pump failure
  2. X FEED operations
  3. On ground for APU start
    - IF AC power is available
16
Q

What causes EMER LIGHTS to illuminate automatically if ARMED is selected?

A

Loss of D.C. Bus 1

Or airplanes electrical power is turned off

17
Q

When do the NO SMKG and FSTN BELTS lights illuminate automatically?

A

When oxygen masks are commanded to deploy

18
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
