Creedy ever heard of CAO48?
Isn't it all pretty clear as the defined by CAO48:
"flight time means the total time from the moment when the aircraft first moves under its own power for the purpose of taking off until the moment it comes to rest at the end of the flight."
Why is there doubt: surely it's from push-back (that is, the aircraft first moves for the purpose of taking off) until the end of the flight (which has to be when finally at rest at the gate)?
As for 'tour of duty', CAO48 is also quite clear:
tour of duty means the period between the time a flight crew member commences any duties associated with his or her employment prior to making a flight or series of flights until he or she is finally relieved of all such duties after the termination of such flight or series of flights and includes reserve time at the airport.
Again, why should there be doubt unless one is trying to push the envelop to his or her advantage?
