where does GPU plug in
right, aft fuselage
(close to under the tail by apu exhaust)
only power source that will power every DC bus
GPU
What does GCU do
voltage regulator
protects from reverse flow
stabilizes bus bars at 28.5
protects over voltage at 32.5
what are generator control units
provide output stabilization and load equalization
generators share load through bus tie and CGU ensures generators are carrying proper amount of load and output
GCU protections
reverse current flow
overvoltage
over excitation
how is pressure in aircraft controlled
by how much air is let in or out of cabin
rate knob for cabin can change cabin VSI
