By A/C I meant Alternating Current (Not Aircon).
So it lost all AC, and thus DC.
Standby power is a 96lbs Nicad battery feeding a static inverter that puts out 115v for about 1 hour to feed some essentials in the cockpit like VHF1, backup NAV, stby instruments with ILS. A bit like a bug smasher. Engs run ok using their own dedicated generators to power the FADECs. Fuel is gravity fed (i think).
The Self Loading Freight would be sitting in the quiet cabin (no recirc fans) in the dim battery powered emergency lights. PA also works.
It would have got interesting after 1 hour. No VHF, NAV, ILS, or Stby insts (except the magnetic compass).
Not being a pilot I am not sure how dire this would be. Comments please.
