Hopefully this incident inc this thread will prompt pilots into fully understanding what they are trying to achieve prior to & during an evac. I was no ace, but was always astounded at the “flaffing” about on the simulator when similar scenarios were presented.
Granted real life is somewhat different (I did have several incidents in my career). Understanding what you need to do as second nature & communicating that to your colleague is all that is required. Communication with the cabin is part of what you are trying to achieve. (Stop check list/continue checklist (ecam) at appropriate moment gives time for cabin communication)
