So CASA's ruling is "when the aircraft first moves under its own power for the purpose of taking-off until the moment at which it comes to rest after landing". Am I right in saying that means when the plane starts moving from where it was parked to the runway, including taxi/waiting time, flying, landing and taxiing back to the parking area?
If that's the case wouldn't VDO be better as you accumulate all that time waiting around to take-off anyway?
