Departure times
With a scheduled departure time of 12.00, for example, is that the time that the plane pushes back from the gate or when it should be starting its take-off roll?
I have read that in the States if a plane pushes back at the scheduled departure time it is considered "on time". That would seem to indicate the departure time is anywhere between pushback and take-off roll but I would appreciate anyone's help in clearing this up for me. Conversely, what is considered the scheduled arrival time...the touch down onto the runway or the gate arrival? I'm guessing the landing time since many of you probably sit for a bit waiting for a gate to open.
Cheers!
