Flight On Batteries: All Eng/Apu GENs have failed and the EMER GEN is NOT on line. You only have HOT BAT BUS 1+2, parts of DC ESS BUS via BAT2 (parts are shed) and parts of AC ESS BUS via ST INV and BAT 1. My Reminder: LH ND is OFF!
EMER ELEC: All Eng/APU GENs have failes but the EMER GEN is on line. You now have AC and DC ESS Bus and off course the HOT Busses powered. My Reminder: LH ND is ON as it ist powered by the AC ESS SHED BUS, which is now on again!
Note: The EMER GEN can only be powered by the RAT via the BLUE HYD system.
If the RAt is extended, you get a status reminder 'RAT OUT' on the E/WD. But RAT extended does NOT have to mean the EMER GEN is operating.
OK?
