fpvdude,
I suggest that you check the links above to the user manual and getting started guide. Do some reading on the airservices projects webpage too huh?
Airservices Pilot Briefing Services (NAIPS) project
and the other page of interest...
ICAO Flight Planning Amendment 1
Sources tell me that the timing of the change is scheduled for Sat Night 27th Oct to roll out the NIS....So from say midnight 27th Oct, NFW will be dead. Wake up Sunday morning and use NIS.
....and because I RTFM... I see that NFW files (SPFIB, Flight Plans and Aircraft Profiles) are able to be imported into NIS for use and storage online.
The ICAO mandated flight plan change is to roll out on Sat Night 10th Nov so again, wake up Sunday Morn, 11th Nov and flight plan with the new format.
