I think the simple solution here is to modify the autopilot config so the input is not from a vacuum driven heading indicator since you don't have one, but from a different property that you do have. The autopilot is designed to be very configurable in this respect and even though it can be com

Hi, In the course of developing the KC135, I noticed that parts of the autopilot function do not work in that model, copied from the B737 - the bits described as vor/loc and app. Investigation showed that the cause was simple - in JSBSim a jet ac does not have vacuum system. No vacuum - no Heading
