He switched on the APU immediately after engine blowback. According to the Airbus that’s the 15th thing on the list to do.
If he had followed the damn rules, we’d all be dead. Now, another question discusses the importance of the APU to the crashbut my question is, why is it so far down the list? I suspect the above is dramatized somewhat, but it does seem odd that it’s so low.
Airbus A A QUICK REFERENCE HANDBOOK
What does Airbus consider more important in their handbook? The assumption was that a multiple engine failure happens at altitude, for instance in cruise while flying through volcanic ashes. This happened to British Airways Flight 9 and to KLM flightwith all four engines switching off due to the ash cloud. Total engine failure at altitude buys time, and if time is available first priority is to attempt to re-light an engine. APU will probably be off during cruise, and given the choice to re-light an engine or to light the APU it is clearly the engine that is the most beneficial to start.
All-engine-failure in aitbus is very very unlikely.
It is a function of number of engines – in a four-engined aeroplane, the chance of all airbis engines failing is assumed to be super extremely incredibly unlikely.
So very uncommon that the only practical consideration would be a common mode failure from external causes, such as the volcanic ash cloud. Procedures are written for the least unlikely events, and updated according to events that actually happened.

A320 QRH Bold Title, color title box, etc?
In the movie Sully we have this section of dialogue He wasn’t following proper procedure at all. Machavity 2, qrn 5 Starting the APU is actually the 11th item on the checklist for dual engine failure, and quite a few items can be skipped like the relight attempt, oxygen masks, notifying ATC, etc.
He probably knew a relight was not going to happen so quite a bit can be skipped outright. Here are the excerpts from the QRH for the Adual engine failure. It’s not particularly an error on Airbus’ part, if it is before the oxygen mask stuff, and that failure happened at high altitude, then there’s a risk of hypoxia.
This is where memory items and training and common sense come iarbus. Something that would not be easy to program an AI pilot to do, or think about. And it’s not just technobabble? It wasn’t Star Trekwhere the names are made up, and the points don’t matter.
