This command sets the altitude model setting for the current scenario. The default setting is ON.
When the model is active, the units will compensate for the altitude change resulting from the difference between the ENU plane and the ellipsoid model of the earth. This only comes into play when traveling over large distances. When set to ON, the trajectory will maintain the altitude throughout. If set to OFF, the movement will continue on an ENU plane that is NOT bent with the ellipsoid, resulting in the altitude increasing as we get further away from start position.
As TIME argument only IMMediate is supported.
