Primary electrical power is provided by: two IDG. one IDG. four IDG. an integrated drive generator.

Which items supply DC power. TR, Battery, battery charger. Battery, hot battery bus, battery charger. static inverters, battery charger, TR.

Which are the main principles of electrical system. No paralleling of AC & Connecting source of power automatically disconnects an existing source. paralleling of AC & Connecting source of power automatically connects an existing source. No paralleling of AC & Disconnecting source of power automatically connects and existing source.

APU supplies power to. two AC transfer buses. One AC transfer bus. two DC transfer buses. One DC transfer bus.

Elecrtrical power system may be categorized into three main divisions. AC, DC, Alternate. AC, DC. AC, DC, STBY. AC, DC, TRs.

External power can supply power to. Both transfer buses. One DC bus. One transfer BUS. Service GND bus.

When can ELEC light illuminate. Only on flight. Only on ground. Both ground & air. Only ON for maintenance.

Why does ELEC light illuminate: Fail on the DC or stby pwr. Failure on AC. Failure on battery.

SOURCE OFF light means. Source selected to power the opposite transfer bus. Source failure. Source not selected on the side of the electrical failure.

Who feeds AC stby Bus. AC transfer bus 1. AC transfer bus 2. DC standby system.

How are the IDGS lubricated. Oil. Air. Fuel. Mixture.

The transfer bus can be powered by any available source through: Tie bus with the BTBS. Tie bus. BTBS.

For single generator operation which items are shed first. Galleys and main bus 2. Galley and main bus 1. Main bus 1. Galleys.

The generator DRIVE amber light is iluminated when. Low pressure is sensed in the IDG. Low oil is sensed in the IDG. High oil is sensed in the IDG. High oil pressure is sensed in the IDG.

How is apu load shedding in flight and which items are shed first. Main bus, galley bus 1. Main bus, galley bus 2. IFE. all of the above if limits still exceed.

DC power system is supplied by: 28 volt DC and 3 TR units. 24 volt DC and 3 TR units. 3 TR units. All of the above.

How can i manually restore the APU load shedding. CAB/UTIL power switch to off. IFE power switch to off. APU power switch to off. None of the above.

The TRs convert. 115 volt AC to 28 volt DC. 115 volt DC to 28 volt AC. 110 volt AC to 24 volt DC. 115 volt AC to 24 volt DC.

AC transfer 2 bus failure, what happens with TRs. TR2 fails, TR3 switches to the AC Tranfer bus 1. TR2 fails, TR1 switches to the AC Tranfer bus 2. TR2 fails, TR3 switches to the AC Tranfer bus 2. TR2 fails, TR3 switches to the DC Tranfer bus 1.

A fully charged battery has sufficient capacity to provide standby power for a minimum of. 30 min. 40 min. 20 min. 60 min.

Battery voltage range is. 22-30 volts. 20-30 volts. 24-28 volts.

Minimum battery voltaje is. 23 volts. 24 volts. 22 volts. 21 volts.

What is the voltage of the battery. 24 volts. 28 volts. 26 volts. 115 volts.

The standby power system provides. 115v AC and 24v DC. 24v AC and 115v DC. 115v AC. 115v DC.

When does the Cross bus tie relay automatically opens. When the Glideslope is captured or bus transfer switch to off. When the Glideslope is engaged or bus transfer switch to off. When the Glideslope is active or bus transfer switch to off. None of the above.

the battery charger is connected to.. Service bus 2. main bus 2. AC transfer bus 1. Service bus 1.

The static inverters converts. 24 volt DC from the battery to 115 volt AC power. 28 volt DC from the battery to 115 volt AC power. 24 volt AC from the battery to 115 volt DC power. 24 volt DC from the battery to 115 volt DC power.

The alternate power source for standby power is... Apu. IDGs. Battery. None of the above.
