Q

When ACMP 1 is set to AUTO when will the pump turn on?

A

Takeoff: Flaps set to greater than 0 and 50kts ground speed OR Thrust levers at TOGA
In Flight: Flights great than 0 OR EDP failure OR engine failure

17
Q

When ACMP 2 is set to AUTO when will the pump turn on?

A

SE Taxi: If Engine 1 is running and parking brake is released.
Takeoff: Flaps set to greater than 0 and 50kts ground speed OR Thrust levers at TOGA
In Flight: Flights great than 0 OR EDP failure OR engine failure

18
Q

When ACMP 3b is set to AUTO when will it turn on?

A
