The F-16 is neutrally stable. It is not unflyable without its SAS, the pilot just has to work harder at it. If the FCS of the real thing has a direct mode (i.e. the control surfaces do exactly as commanded by the pilot with no adjustments made by the computer), this is probably what it

I'm starting to ponder the idea of implimenting a simple C172 electrical system. I know it would be nice to develop some grand system so you could model any aircraft's electrical system of any complexity all in xml. I probably don't have time for that, and I'll want to start small and

Once upon a time, you were sitting and writing: But, even if I do something simple, this could have a pretty far reaching impact. Each instrument would have to check the status of the electrical system (voltage? on/off?) IMHO 1. Voltage - how much (5,12,24,48,,,)V, 2. Max current - how

Currently, when the system is serviceable, suction is just fmin(rpm/300, 5), to give usable suction from 1500RPM on up. Once we wire this into steam.cxx, we can model vacuum-system failures. There is a slightly more complex model for vacuum in Steam. I suggest you snag it and then delete it
