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.

Supply the landing gear.

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!

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!
