The AMSO Saturn V autopilot supports a launch azimuth correction. A correction angle, in degrees-decimal, can be specified in the launch scenario file, with parameter "AZIMUTCOR". This azimuth correction is applied to the natural launch azimuth, which is the ground heading minus 180 degrees (Apollo fly on the back during ascent). Autopilot executes this correction by rotating Saturn V in the very beginning of the flight. For example "AZIMUTCOR -18" will aim a launch azimuth of 72 degrees. According to NASA specifications, "AZIMUTCOR" is limited in the range -20 to +20 degrees, which correspond to an azimuth range of 70 to 110 degrees. Values out of range are trimmed automatically to appropriate limit.
