+xMichael, could you help us to reproduce the original problem you were having please? We need to fix it even if you've found a workaround. I just tried planning a route and saving straight as a KML but I found no problem. How do I see the problem?
As attached files you'll find a planned route (stored as SD Flightplan). I also saved it as KML-file.
Uploading of KML File is not possible....
Please note that the direction of flight is from east LOAV) to west (LOWS).
Opening the KML file in Google Earth Pro shows the magenta line (left hand sidebar of GoogleEarth "My Places -Temporary Places" shows the route and two sub checkboxes Route Fly-Through and Magenta Line.
Left Clicking on Magenta shows on top of the left sidebar window below a button with a symbol of 3 (way)points linked with a line and a small triangle like a play button. Activating this button starts the fly through, starting at LOAV.
Left Click of the the Route-Fly through line brings another button on the sidebar with the cam and the play symbol. Clicking this button makes the virtual cam move to the end of the route (in this route LOWS). On the bottom of the screen (satelliteimmage) there is the small control panel with the back/play/forward button. Pressing play, the "cam" lifts a few meter and returns to its position on the runway.
If you'd like to have the KML-file, pls post, how I can send it to you.
Best regards
Michael
