1

Will the DOME lights activate with the battery switches turned OFF?

NO
Batteries must be ON/AUTO

2

What conditions have to be met for the CVR data to be erased?

Aircraft on ground
Parking brake set

3

What lights are not illuminated by the ANNUNCIATORS TEST?

Master warning/ Caution
Fire Test Lights
GPU Pushbutton light
EMRG/PRKG Brake light

4

What is normal AC BUS source priority?

Respective IDG
AC BUS TIE

5

What is the AC BUS TIE source priority?

APU
GPU
IDG

6

What occurs if OFF is selected on IDG 1?

Opens the IDG contactor
Isolates IDG from respective bus

7

What does the illumination of the amber LED indicate?

Which IDG to disconnect
Associated with IDG OIL caution EICAS

8

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

No

9

When will the AVAIL light illuminate?

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

10

When will "in use" illuminate?

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

11

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

Isolated respective TRU from its associated D.C. BUS

12

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

OFF supplies power to the HOT BATT BUS 1 only

ON connects battery to D.C. ESSENTIAL BUS 1

13

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

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

14

What happens when XFEED is set to LOW 1

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

15

When will AC (fuel) PUMP 2 activate automatically?

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

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

Loss of D.C. Bus 1
Or airplanes electrical power is turned off

17

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

When oxygen masks are commanded to deploy

18

What happens when you pull the fire EXTG handle?

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

What happens when you press the APU guarded pushbutton?

1. Closes APU shutoff valve
2. Discharges APU fire bottle

20

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

No

21

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

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

22

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

1st push discharges HIGH rate bottle
2nd push required to discharge LOW rate bottle

23

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

1 st push discharges HIGH rate bottle
60 sec later LOW rate automatically discharges

24

What happens to electrical power during a normal APU shutdown?

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
