it seems likely that to end up in the emergency configuration the AC buses would be so damaged that the APU generator would be unlikely to latch anyway
How useful the APU in EMER ELEC CONFIG ? Would be useful at the point that we can go out of EMER ELEC CONFIG ...
Dual GEN/IDG failure or TR1 Failure + GEN2 Failure and vice-versa ... why should AC buses be that damaged ? I mean APU GEN can yet be connected and supply the whole network here ...
