Hey, if some iron-handed JATWISH ruler wants to gas those who we call ruthless terrorists that would just wind up killing Christian and Kurdish minorities in Iraq and elsewhere anyway, what's the difference?
Your crew duty day would end after engine shutdown and all post-flight duties were done as well as any preflight planning for subsequent missions. The latter can definitely be murky, especially on the road.
I always thought the vol 3 was pretty clear. Don't have one handy to copy/paste.
Is there a specific issue?
FDP ends at engine shutdown (and is shorter) because that's the longest time that one can operate an aircraft. Crew duty is the additional ground items.
Bingo.
Dudes have been busting their asses to get as far as they did (different topic as to what they had to do to get there...it was work and time either way) only to be "rewarded" with this great opportunity to spend even more time away from the fam to the tune of 365 days. No way.
