Hello Dave,
hope you can find an answer and that it's easy to solve:
Today I wanted to start my first transatlantic flight from EDDK to KBOS.
I build a flightplan with FSBuild and compiled it with PF2000.
I loaded the adv in PFE and found the bar for selecting the oceanic procedure to be started and end greyed out. I loaded another adv in PFE e.g. from EDDF to LGAV and it was available for selection.
After trying and trying I found out that as soon as any NATS waypoint like 5430N is in the flightplan the oceanic feature is not ready.
Maybe you can try it on your system?
Kind regards,
Axel
