For example, if you were to operate a flight immediately upon arriving at the destination, the time spent in deadheading is considered duty.
Likewise, specified rest generally must be provided if not operating until the next rotation.
Lets rephrase it:-
If Pilot A travels Jumpseat in his own airline,after operating a sector.
If Pilot A travels Commercial in another Airline,after operating a sector.
To reach a place X a distance Y away.
Is it part of his FDTL.Since in both cases Pilot A is just a PaX or maybe a non optng crewmember.
I may not win often, but I damn well never lose!!!
