Correct! Wrong!

The Emergency generator is powered by:

The Static Inverter.

A Ram Air Turbine (RAT).

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

Correct! Wrong!

During EMER GEN automatic start up sequence:

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

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

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

Correct! Wrong!

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

Loss of the corresponding AC or DC bus.

No effects on flight management.

APU generator required operational.

Correct! Wrong!

With APU GEN and external powers supplying the network:

APU supplies AC 1-1 and AC 1-2 only.

APU supplies AC ESS only.

APU is supplying left side, external power A is supplying the right side.

Correct! Wrong!

The minimum number of generators required to supply the whole network is:

One engine generator.

One engine generator and the EMER GEN.

Two engine generators.

Correct! Wrong!

An engine generator is driven:

At a ratio of 5 to engine speed.

Direct from the Accessory Gear Box (AGB).

By an Integrated Drive Generator (IDG).

Correct! Wrong!

When the MAINT BUS switch is on:

Only the DC buses are powered.

The electric network supply is limited to Ground Service items.

It is for the purpose of operating the cargo door only.

Correct! Wrong!

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

Electric supply to CB is normal.

There are no CB tripped or pulled.

No fault detected in Electronics Equipment Bay.

Correct! Wrong!

According to these indications which AC BUS supplies the ESS TR?

AC 1-1 BUS.

AC ESS.

AC 1-2 BUS.

Correct! Wrong!

Each engine generator supplies power to:

Only its assigned BUS in all cases.

The BUS on the opposite side in normal operation.

Its assigned AC BUS in normal operation.

Correct! Wrong!

In flight, APU not running, an engine generator has failed. What is supplying the corresponding AC BUS?

Corresponding AC BUS is not powered. APU must be started to recover AC BUS.

The other side outer engine generator.

The other generator on the same side as the failed generator.

Correct! Wrong!

The MAINT BUS switch is located:

On the FWD Circuit Breaker Panel behind the cockpit.

On the overhead system panel in the cockpit.

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

Correct! Wrong!

When ECAM shows "ELEC ECMU 1 FAULT":

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

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

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

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!

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

Automatic management of contactors.
