This is something that has been on my mind for a while, too. I wouldn't say that the inputs to the FCS or A/P should be from the instruments always. For my uses, in JSBSim, we might want to have a "sensor" class that can be failed in one or more ways, and biased, or massaged in some way so as to model a real sensor reading instead of using (as you have pointed out) the perfect EOM state data all the time. With some creativity, in the JSBSim case with our FCS components and the sensor class, maybe we could eventually model independent sensors feeding into quad redundant FCS strings. Not sure we could vote a signal out using the general purpose system we have.
