Lost with the PFD GPS course

[hjsmuc 393]

Sorry if this is another stupid question about the Hawker navigation.

 

Have a look at the screenshot, it shows a GPS course to 357 and a distance of 2964 NM. Problem is, there is no flight plan active, not in the GTN750, not in Prepar3D. I moved the aircraft to different airports and the distance changed. But I have no clue where it gets the heading from. If it was to be the CRS course how does it know a distance? Any help appreciated.

 

Checked against a new scenario with the Phenom 100. Same. Where is the dst coming from? Only suspicion is the flight plan association of SimLauncherX but why then in a new scenario. Also, the distance to the last airport of the SimLauncher scenario was completely different.

 

FINAL CONCLUSION: It was indeed the flight plajn associated with the flight file through SimLauncher. No fault of this marvelous tool though. Sometimes I find that it makes sense to clean up the stored flights and start a scenario from scratch.
