This is a question for those of you in Ops/Dispach who spend lots of time attributing delays and calling flight's off on time, or obviously delayed.
I just wondered what sort of arrangements different Airlines have with their Ground Handler in terms of what they are permitted to call on time? i.e. what is the period of time after STD they are permitted to call the flight on time when the A/C actually pushes back and do you call this by 'chocks-off', 'A/C flashing', 'Doors shut', 'A/C literally being pushed'....etc, as have seen and heard all of the above being used.
Would be interesting to hear potentially varying comments on this, as this has always seemed a little bit of a 'grey area' to me not being from an OPS background.
