Command Flight Planner
In case anyone is still struggling in Command Flight Planner (after assuming AsA got it right and switching) there are some instructions for switching back to the old NAIPS interface accessible from the front page of the Command Software Web site.
I share Bevan's concerns about the compressed time frame for the flight plan changes. I have it coded, customers can update their aircraft profiles in preparation, and I expect it to work but I don't have the degree of confidence I'd like.
I won't be surprised if the two change events merge into one on 11 Nov but there's been no word yet. The global go live date for the new FPL is 15 Nov, so there is little wiggle room without being exposed to international problems.
