Airbus A320 Electricals

The engine generators and APU generator are rated at _____ KVA.

• 50

• 70

• 90

• 110

The number 1 AC bus channel normally supplies power to _____ and to the _____ bus which supplies power to the _____ bus.

• TR2 / AC ESS SHED / DC ESS SHED

• TR1 / AC ESS SHED / DC ESS

• TR1 / AC ESS / AC ESS SHED

• TR1 / AC ESS / DC ESS SHED

The normal priority for supplying electrical power to the AC busses is:

• External power, engine generators then APU

• External power, APU, then engine generators

• APU, external power then engine generators

• Engine generators, external power then APU

The BATTERY BUS is normally powered by:

• DC BUS 2

• DC BUS 1 and DC BUS 2

• DC bus 1 through a DC tie control relay.

• DC bus 2 through a DC tie control relay.

An AC ESS FEED switch located on the overhead panel shifts the power source for the AC ESS bus from:

• AC bus1 to AC bus 2

• AC bus 1 to AC Grnd/Flt bus

• AC bus 2 to AC bus 1

Which of the following AC busses can be powered by the emergency generator?

• AC bus 1

• AC bus 2

• AC ESS bus / AC ESS SHED bus

The RAT is connected directly (mechanically) to the Emergency Generator

• True

• False

The emergency generator supplies power as long as:

• The landing gear is down.

• The RAT is deployed.

• The RAT is deployed and the landing gear is down

• The landing gear is up.

The BAT FAULT light will illuminate when:

• Battery voltage is low

• Charging current increases at an abnormal rate

• Charging current decreases at an abnormal rate.

The IDG Fault light indicates:

• An IDG oil overheat

• IDG low oil pressure.

• IDG low oil pressure or IDG oil overheat

• IDG has been disconnected
