I fly in the F-15C. I tried the Route manager. I loaded the fp from an file and didnt choose anything in the panel. so it took an dep rwy as it likes (or maybe based on the wyp). But i started on an other rwy and activated the ap in the air. In the file i had no hight defines so i did auto pitch. to the first wyp it flown by itsself. After that the Rout manager cycled tho the wyp after and on the map the way was gray,not pink anymore. the message from the terminal is attaced. i originally started FG from the terminal
fixed it with enabeling scenery download.
but had to enable the button in the laucher.
wrote it in the additional settings and the scenery didnt load
