an over-voltage of ___ or higher will cause the GCU (generator control unit) to automatically open the GLC
32.5
What does the GCU do
provide output stabilization and load equalization
automatically switches from starter mode to generator mode
in generator mode, it will act as a voltage regulator
controls the generator by directly controlling the GLC (generator line contactor)
provides reverse current flow protection
Why are our batteries 24v but our system is 28v
The voltage all together needs to be greater so that the batteries can charge off of the extra voltage
How is the electricity in the electric system distributed
busses
How do we test the volts for our battery
the battery pushbutton connects ammeters to batteries to show the charge rate of the batteries.
it is hot-wired to the battery so there is no need to turn anything on. just turn a knob so that we are looking at it specifically.
What should our battery amps be at for takeoff
needs to be below 20 amps
GPU (ground power unit)
standard 3 pin, 28 volt DC ground power receptacle located on right rear fuselage
what is the only thing that can run everything with engines off
GPU
What information does the cabin triple indicator give us
cabin altitude
differential pressure
rate of change
Cabin pressure at FL 410
7500
8.55 PSI
How do we control cabin pressure
pressurization is achieved by supplying bleed air into pressure vessel and controlling the outflow
Max cabin pressure differential
8.55
Max Negative Cabin Pressure
-.5
Max Cabin Over Pressure
8.6-8.8
