spar fuel valves
parking break

23
Q

with EXT power AVAIL light illuminated, what buses are powered

A

HOT BAT and ground handling buses

24
Q

how many batteries are there

A

2 - the main and APU battery

25
Q

when does UTIL BUS shedding occur

A

BOSS
Both thrust levers advanced to T/O range on the ground with engines shut down
Overload-electrical load exceeds power available
Starting engines
Single generator source (gen or eng failure)

26
Q

with a left AC BUS light fault, will the captains flight instruments fail?

A

no, automatically powered from the right main AC BUS

27
Q

what is the purpose of the BUS TIE system?

A

PPI-Prevent, provide and Isolate
Prevent paralleling of the left and right main buses
Provide power to both main buses
Isolate faults

28

only on the ground

29
Q

what does the HDG provide power to?

A

BATT and HOT BATT buses
left and right AC transfer buses
Standby AC and DC buses
captains FLT INSTR

30
Q

what are the 5 times that pilot verification is required prior to pilot action

initial position
GEN DRIVE
thrust levers
fuel control switches
fire switches

31
Q

is it possible to shed the galley bus and not the utility bus

A

yes

32
Q

how does the APU get its fuel

A

left FWD AC pump or the DC pump in the left tank

33
Q

what happens when you move the APU start switch ON?

A

the fault light cycles on then off
the APU door opens
the APU fuel valve opens
turns on the DC or AC fuel pumps
arms APU bleed valve to open

above 85kts and BOTH thrust levers at IDLE

38
Q

which brake systems have anti-skid capability

A

All of them

39
Q

when the APU RUN light flashes twice, what does this mean?

A

it is testing both APU circuits

40
Q

what happens when you turn on the fuel jettison nozzle switches are selected ON?

A

jettison transfer valves open
jettison pumps operate (if installed)
sheds side window heat
