Airbus APU autoshut down during auto engine start
If APU autoshut down during engine start, start abortion results. How would you handle it?Dry cranking necessary? How? External bleed (If no engine started)? Crossbleed? (If one engine started)
For next start attempt, if no ground air cart available, and one engine started, can you keep the engine running while asking for bridge to reconnect to allow engineer to ADD the APU for dispatch? This is to preserve crossbleed start possibility.
FCOMs only mentions dry cranking under APU bleed, but for after APU shut down, I can't find any other reference. Thanks for the valuable advices!
