What is the correct power-up sequence for A380
How do you power up the cockpit in A380? Assuming GPU (Ground Power Unit) is not connected yet:
1) Turn the batteries 1,2,ESS on?
2) Connect External Power.
3) Turn the EXT PWR switch (ELEC) on?
I was under the impression that without DC ESS on, BAT 1 and 2 alone will not anything to the aircraft? Does anyone know the correct procedure?
