Hi guys
I've been trying to avoid creating a new topic by sifting through the existing topics to add this to, but I couldn't find a directly related one.
I might as well be a bit too excited about this revelation and I suspect you folks out there may have already worked this out; so, dear admin please feel free to delete my topic if you find it inappropriate!
I've been using ProATC-X to create flight plans including SIDs and STARs and when you put your 727 in GPS mode the aircraft follows the exact waypoints and intersections including those of the SIDs and STARs beautifully.
It's interesting because with ProATC-X (I don't know of any other third party ATCs) the STAR is assigned in-flight and the GPS path immediately gets updated to reflect the STAR waypoints!
Now a couple of things to remember:
1. you won't have the luxury of VNAV, so your vertical navigation is up to yourself to manage; however the ATC will guide you with altitudes and restrictions are shown in a table just lower left of the screen in ProATC environment
2. you need to have updated your FSX NavAid database so that the ATC software (which is loaded with AIRAC database) can talk to your GPS and insert the waypoints; there are free DBs available to download but I'm unable to provide direct links as this is only my first post; anyhow I'm happy to share my source when I'm allowed (I'm sure many of you already know about them anyways)
3. by the same token you'll be able to fly ANY aircraft not equipped with a FMS using the above method

Sorry for sounding a bit excited about something this simple, and most specially with my first post.
Any ideas??
