Hey an A320 authentic checklist that is awesome! Thank you very much 
In theory looking up and seeing every light in the overhead panel off while the engines are running and no ECAM warning is enough so no checklist is needed to perfectly fly the Fenix.
But I love the real authentic stuff - authentic like the Fenix Airbus is - that´s why such PDF files are always highly interesting because this is also a great way to check how authentic the Fenix cockpit systems are simulated compared to real Airbus procedures.
This is a good PDF to bring authenticity to the next level.
