BAT ONLY STARTING OF THE APU (A320)
Hi all,
A little question about the start of the APU in the Airbus A320 (msn446) when flying on BAT ONLY.
In the Fcom Pro-Abn-24-Q elec Emer config:
"CAUTION In case of simultaneous engine generator failure, the probability of a successful APU GEN coupling is low. Therefore APU start attempts should be avoided, as this will consequently reduce the flight time on batteries only (by about 3.5 min for one start attempt)."
But how is it possible to start the APU when the ECB-starter is INOP on BAT ONLY like said in QRH?
QRH Abn-24.01A
Thanks a lot for your answers.
