I haven't found a way to force the route finder to include a nat track for NA routes. It just creates a route that jumps between different tracks.

 

Not sure why that's happening, but even RW routes do it, actually.

 

KLM652's plan (for 29.08.13) jumps tracks:

SWANN V268 BROSS J42 RBV LLUND BAYYS PUT WITCH ALLEX N93B CYMON NATW DOGAL NATW BEXET LIFFY UL975 WAL UM16 DOLAS UL603 LAMSO

 

NATW dumps onto BEXET, but picks up at DOTTY.  CYMON is actually NATX, which is what's filed in the KLM flight as the beginning of the NAT portion.

 

Granted, all of this is limited by the fact that NATs change, but still.  Using the route currently filed versus the NATs currently available.

Regarding not using NAT tracks when creating auto routes, Christian Grill writes in his supportforum that it's because of a faulty navigraph cycle. I still use the one that came with the app: 1302

 

Edit: updated to 1309 and now it works.

AS2012 is a weather program, PFPX uses data weather either his one or the one of your addon to find the best route. AS 2012 "just" handle the weather within your sim, it does not give you routes, or anything like performance computation, to know fuel burns and flight times.

 

FSBuild is used to make route and only that, I believe it "only" find a best route from its AIRAC, but does not account for wind, and doesn't go far in fuel consumption and things like that.

 

 

TOPCAT is used only to compute takeoff and landing speeds and actually PFPX can call TOPCAT to get you this part on your complete flight briefing. But it does only compute speeds dependning on aircraft weight and weather.

 

That is a completely different piece of program. I'd say in all you listed you can remove FSBuild, and use PFPX with the two others.

thanks for your clarification, got i all mixed up.
