Since FSNav is being discontinued, I would like to find another app performing the same purpose (planning and route calculation) Upon looking at other apps I found none that support a small view that can be seen inflight such as FSNav.The only reason I would not stick with FSNav is that it has outdated SID/STAR and Airway info and an inconvenient interface.I am not sure if there are other apps that are like FSNav in that they connect directly to the autopilot. This is one of the biggest features of FSNav that I want in another app.I also need something that runs on FSX as I may soon be upgrading :)

For me, the best planner is FSBuild, because it offers everything that I need for accurate flight planning and is the only planner that I am aware of that is able to take weather (even Active Sky) into consideration. It's doesn't look like much, but it works for me.FlightSim Commander is also great, but a little bit to limited for me. The moving map is nice, but that's not required in a planner for me.The guys from Hifisim are allegedly working on a new planner, which will be definitely worth to watch out for.Pat

I was also looking at FSBuild, and its ability to export to the PMDG FMC makes it the best option for me
