Creamie, are you arguing that the definition of 'under its own power' precludes the attachment of a temporary motive force (tug) which is physically pinned to the aircraft so as to form a single unit for the purpose of moving the aircraft, even though the tug operation
is at the discretion and direction of the aircraft captain?
If so, would Road Train drivers need a 'Multi Combination' drivers licence if the trailers 'pinned' behind, could be considered as not part of vehicle unit.
