During EMER GEN automatic start up sequence:

It is not recommended to push the MAN ON p/b to confirm EMER ELEC CONFIG on the EMER ELEC PWR Panel.

The MAN ON p/b must be pushed to extinguish red fault light on the EMER ELEC PWR Panel.

Red fault light on EMER ELEC PWR Panel will remain on until the EMER GEN reaches its normal output.

Correct! Wrong!

The EMER GEN is powered by a hydraulic system pressurized by an engine driven hydraulic pump. Pressing the LAND RECOVERY p/b switch will:

Normally recover the AC and DC LAND RECOVERY BUSES and the components for approach and landing.

Operate when the gear is extended.

Correct! Wrong!

Each engine generator supplies power to:

Only its assigned BUS in all cases.

Its assigned AC BUS in normal operation.

The BUS on the opposite side in normal operation.

Correct! Wrong!

The main function of the MAINT BUS switch is:

To power the AC and DC systems when the aircraft is on ground.

To allow EXT PWR to supply AC and DC ESS buses and their respective shed buses.

To allow selected ground equipment to be powered without powering the entire electric system.

Correct! Wrong!

The MAINT BUS switch is located:

On the Purser's Control Panel in the FWD cabin.

On the FWD Circuit Breaker Panel behind the cockpit.

On the overhead system panel in the cockpit.

Correct! Wrong!

This ECAM ELEC page shows:

GEN 4 pb is set to Off and engine 4 is running.

GEN 4 pb is set to On and engine 4 is running.

GEN 4 pb is set to Off and engine 4 is not running.

Correct! Wrong!

The Emergency generator is powered by:

The Static Inverter.

The GREEN hydraulic system when pressurized by engine 1 or 4 driven hydraulic pump or by a Ram Air Turbine.

A Ram Air Turbine (RAT).

Correct! Wrong!

When ECAM shows "ELEC ECMU 1 FAULT":

ECMU 1 controls Generator Line Contactors (GLC 3 and 4) and you should reset generator 3 and 4.

ECMU 1 controls GLC 1 and 2 and you should try to reset corresponding generators.

ECMU 1 controls GLC 1 and 2 and you should not reset corresponding generators.

Correct! Wrong!

One function of the Electrical Contactor Management Units (ECMU) is:

TR contactors monitoring.

Automatic management of contactors.

Control of AC and DC bus ties, except TR contactor.

Correct! Wrong!

According to this ECAM ELEC page:

BAT1 and BAT2 are faulty.

BAT1 and BAT2 are supplying the DC network and discharge current is 40 A.

BAT1 and BAT2 are not connected to the DC network.

Correct! Wrong!

As shown on this ECAM ELEC page, which BUS is normally supplying the ESS TR?

AC 2-4.

AC 1-1.

AC ESS BUS.

Correct! Wrong!

According to this ECAM ELEC DC page:

There is no degradation in the capability of DC system.

The Static Inverter is being powered because TR 1 is not powered.

The BAT 2 is discharging at a rate of 4 A.

Correct! Wrong!

On C/B ECAM page, the pilot reads "NORMAL". What does it mean?

No fault detected in Electronics Equipment Bay.

There are no CB tripped or pulled.

Electric supply to CB is normal.

Correct! Wrong!

Loss of one generator or TR (except, if lost is due to over current detection) provides:

No effects on flight management.

APU generator required operational.

Loss of the corresponding AC or DC bus.

Correct! Wrong!

According to these indications:

EXT POWER is being plugged and available for use when started.

EXT POWER is plugged, but is not available.

EXT POWER is not plugged and APU GEN is connected.

Correct! Wrong!

What is the meaning of this ECAM?

There is a TR overload.

There is an engine generator fault.

There is an ECMU fault.

Correct! Wrong!

With APU GEN and external powers supplying the network:
