Brief description of the issue:

AI aircraft (offline flightplans) start depart from runway. Then climbs a little but after a couple of seconds, spawn 20-30ft under and start climb again from there. Doing this like 4-6 times with status “fly to waypoint” and then spawn to the terrain with status “taxiing”. This has happen in several airports in su12 beta and with su12, so it is airport specific problem or something else.
