I am simulating the Rascal and it overloads the -l CMAC other locations load it doent run a mission the alt is below the ground.
Terain check

MANUAL> TERRAIN_REPORT {lat : -355443111, lon : 1491653188, spacing : 100, terrain_height : 942.354187012, current_height : 1.55083250999, pending : 0, loaded : 336}

Is this why the plane spins when I try to run the example waypoints unlke when I do it without jsbsim?

How can I set the starting altitude above the ground.
