Max altitude AGL

[Essah]

Mission editor won't let me assign waypoint altitude above ground level higher than 1200 Meters. Is that some kind of limitation in the A-10 Avionics or just a bug?

The agl setting is to allow the AI aircraft to follow the terrain. Can't see any point in setting this higher than 1200 metres. Change the agl setting to msl (mean sea level) and you can have any altitude you desire. The difference is that the AI will fly a straight line between the waypoints (as long as no terrain in way) when they are set to msl as opposed to agl where the AI will attempt to constantly fly the given height above all terrain between the 2 agl set waypoints.
