Whatever the reason may be, the fact that pilots regularly engage in rather complicated and obstruse workarounds shows that cockpit design shouldn't be taken as the holy grail of UX.

Incidentally, I also wonder if the many checklists pilots need to go through before the plane does anything are strictly necessary. It seems like automating these steps and removing associated buttons may be beneficial to reduce cognitive load and prevent operator error (such as happened with the Air India crash last year).
