Seat0A...Because it's a legal requirement?!
SodaPop...I know about the driftdown thing...theres also the decision point (PNR) in relation to diversion after engine failure.
Thats not waht I'm referring to.
What I'm talking about is the use of a Decision Point in fuel planning when you can't carry sufficient out of your departure airport to go direct to your destination.
You can plan to a Decision Point and perhaps continue to destination from there (or divert).
But you could also plan to a different (en route) 'destination' and 'Re Clear' from there to your true destination.
I want to know if the rules are different in these two scenarios.
