While in flight, with all three generators offline, which buses are powered?
ESSENTIAL only
What is the maximum amperage on the GPU?
1,500 Amps
If the aircraft is down to essential power only, how long will the batteries last?
1 hour
How long will the standby battery power the ISI?
3.5 hours
While in flight, which electrical buses are powered with only one generator online?
ESSENTIAL and MAIN
What is the minimum battery temperature for takeoff?
-20 C
What is the maximum amperage for two or three generators?
400 Amps
What happens with the right battery during APU start?
During APU start the right battery is isolated from the aircraft system and powers the APU starter.
What is the max amperage for one generator while on the ground?
400 Amps
What is the maximum amperage for one generator while in flight?
500 Amps
What is the transient limit for all generators?
600 Amps for 5 minutes
What items in the aircraft are powered by the left and right AUX buses?
Cabin DC and AC power, and the copilot side window and foot warmers
What does a green AVAIL message on the electrical panel indicate?
GPU is connected and has the correct voltage and polarity
Which other generator normally shares the load with the APU generator?
Right side generator
With all three generators operating in flight, if the left generator drops offline, what automatically happens?
The APU generator automatically switches to the left side and powers the buses.
Why is the right battery turned on first?
To prevent uncommanded APU start

Seven
What is the max altitude that the APU GEN can be used?
30,000’
Which electrical source powers the left DCMP?
Right generator
Which electrical source powers the right DCMP?
Left generator
What power source is required to use SPPR
Right BATT bus
From where do the left and right DCMPs obtain power?
Right: left ESS bus / Left: right MAIN bus
From where does the refueling panel obtain power?
Right BATT bus
