Aircraft must be off and system must be discharged with the manual accumulator bleed valve.

System must be discharged with the manual accumulator bleed valve.

Correct! Wrong!

If normal DC power is lost:

The hydraulic remains fully operative.

The hydraulic system is powered by the emergency bus.

The hydraulic system is powered by the standby battery pack.

The hydraulic system is inoperative.

Correct! Wrong!
