- What is the primary electrical power,
volts, phase, hertz and current
- What converts variable input speed
from the engine accessory pad to a constant RPM output to the generator.
- AC power to the airplane may be
supplied by the engine driven generators and what other sources.
- CSD oil cooler efficiency is determined
by observing what.
- To
prevent the disconnected generator from being motorized by paralleled
generators the disconnect switch also trips what.
- The
voltage regulator adjusts what to control the voltage output of an isolated
generator
- To
reduce the output of a generator to a minimum. What would you trip.
- What
connects a generator to it's load bus
- To
equalize the loads on the generators. The load busses are connected
together by what
- Damage to the generators might occur if they are not what
- In
order for a generator to be able to supply essential power. its what
must be closed
- The standby bus can be powered from
the essential bus or by what other means.
- The AC transfer bus can be powered
from what two sources
- If residual voltage is 10 to 17
volts, you know the generator is doing what.
- If
the synch lights are out. The generator selected is in what with the
synch bus.
- Normal DC power is supplied by what
- The battery charger receives power
from the bus
- If TR 1 fails.
DC bus number 1 will be powered by
- Failure of a TR is indicated by
what, indicating zero
- The
battery bus is normally powered by What
- With the airplane not powered, What
will be powered from the Battery
- In flight normally the hot battery
bus is powered by what
- What two sources can power the battery
transfer bus
- What illuminates with the loss of
essential power
- When
paralleling manually, the bus tie breaker should be closed when the
synch lights are
- If all generators are lost while
on the ground, the battery switch should be checked on and what
should be turned on/opened
Answer the following as True or False
- In order to check the battery, power
to the battery charger should be interrupted.
- When the APU generator breaker is
closed, the bus tie breakers should remain open
- The
CSD disconnect switches should be selected to DISCONNECT to check their
operation during flight.
- Prior to engine start the electrical
load should be reduced
- Immediately after engine start.
When the first engine driven generator is connected and the APU generator
drops off line, essential power will be lost
Abnormal & Emergency Procedures
- If all generators are lost in flight.
The first action to be taken is to

landing with only two generators operating how many packs on
- One
generator inoperative when should you turn on the 2nd pack
- With
only one generator operating before flap extension do what.
