APU bleed use after APU Auto Shutdown (A320
Happened in the sim to me-Started Eng 1 and during Eng 2 start we had a APU auto shutdown. We followed the Ecam and switched off the APU master accordingly.The APU bleed switch was however,still on.I suggested to my training partner to switch off the APU bleed and attempt a crossbreed engine start.The instructor then paused the sim and told us we don’t need to do anything because since the APU bleed switch is on the Crossbleed would automatically be open so engine 2 would be pneumatically supplied by eng 1 bleed.He said we didn’t have to do a crossbreed engine start supplementary procedure.Can anyone explain this a little better please?
