Max waypoint altitude?

[Caster]

In mission 10 of the ossetia campaign, one of the waypoints is at 26000ft (but shows at ground level in INS). I always go through the waypoints and set proper height as the INS alignment happens. This is fine for all the other waypoints, but not the one at angels 26. Is there a max height? My other thought was that that waypoint is also bulls.

The mirage INS is designed to have its waypoints altitude be at ground level. Editing the altitude of your waypoints to be at your planned flying altitude is not SOP, but nothing prevents you from doing it.

 

WIth the above in mind the waypoint altitude is limited to 25000ft.
