ELECTRICAL

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 A-320 has _______ batteries in its main electrical system. 1. 2. 3. 3 (4 when ETOPS capable).

When no other power is available in flight, the static inverter converts _____ power to AC power for the ______ bus; and ______ powers the _______ bus. BAT1 DC / AC ESS bus / BAT2 / DC ESS. BAT1 DC / AC ESS SHED / BAT2 / DC ESS SHED. BAT1 DC / AC ESS bus / BAT2 / DC ESS SHED. BAT1 DC / AC ESS bus / DC ESS.

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 Generat. True. False.

After landing, in the emergency electrical configuration: the batteries automatically connect to the DC BAT bus when speed decreases below _______ knots. 50. 70. 90. 100.

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.

Do not depress the IDG DISCONNECT switch for more than _______ to prevent damage to the disconnect mechanism. 3 seconds. 7 seconds. 10 seconds. 15 seconds.

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.

If normal electrical power is lost; essential cockpit lighting is maintained for the: Captain’s instrument panel. Standby compass. Right dome light (provided the dome selector is not off). All.

You enter a dark cockpit, what action is necessary before checking the battery voltages?. You have to check that the external power is on. You have to ensure that at least one battery is on. You have to ensure that both batteries are on. You have to verify that both batteries are off.

Having started the APU, how can you get the APU generator to power the electrical system?. The APU generator must be switch on. By pushing the EXT PWR pushbutton thus disconnecting the external power. By pushing the BUS TIE pushbutton. You are unable to as the APU power output is outside normal parameters.

Are there any limitations associated with disconnecting an IDG?. Never disconnect an IDG in flight, or push the IDG disconnect push button for more than 30 seconds. There is no limitation. Never disconnect an IDG in flight, or push the IDG disconnect push button for more than 5 seconds. Never disconnect an IDG unless the engine is running, nor push the IDG disconnect push button for more than 3 seconds.

Which voltage requires recharging or replacing the batteries?. 20 volts or less. 24 volts or less. 25 volts or less. 26 volts or less.

If batteries are the only source of power in flight, how long will battery power be available?. Between 22 and 30 minutes depending on equipment in use. Until the APU is started. Two hours and 30 minutes dependent on equipment in use. 45 minutes dependent on equipment in use.

Which flight control computer will be inoperative with gear extension while in the Emergency Electrical Configuration?. FAC 1 and ELAC 1. SEC 1. SEC 1 and ELAC 1. FAC 1.

Is it possible to parallel generators?. Of course yes. Only with the RAT deployed. The electrical system will not allow “paralleling” of generators. Only one engine generator may be paralleled with the APU.
