| Initial Conditions |
The Initial Conditions tab includes the usual Gun Aiming parameters of Quadrant Elevation and Gun Azimuth. The environment can be selected. In this case I'm using a User Met Table. Spin is calculated from the Muzzle Velocity, Twist and Exit Spin ratio provided. Note that the Spin calculation can be overridden using the Trade Studies tab. A Trim may be entered in the Aero Form Factors section and the projectile Initial Position and Angular Rates are also defined here.
