Pilots are supposed to carry out the mandatory checks before the flight take-off or taxi. But what happens when there is a delay, when the aircraft cannot push back from the gate, due to non-clearance from ATC, or due to heavy traffic etc.
- Do the pilots, re-run the checks, or carry out more extensive checks of the aircraft?
- Do the pilots just chit-chat, eat, or make phone calls to their family?
- Is there any standard procedure to be followed during this wait time?
Edit: As someone tagged this as duplicate, my question no where suggests time spent by pilots during long haul flight, its about what they do when the pushback is delayed. Hope it helps.
