An AHRS has to provide an attitude solution for the aircraft.
Of course, but why is a full attitude solution required for yaw damping?
what do you mean by “steady state yaw”?
Flying with the ball off to one side.
You have some interesting ideas, and I think Embraer needs to hear from you about how to improve their flight control system.
This is an interesting product
The most interesting use is aligning high gain, narrow beam antennas for long range IP networks (offshore applications) that need to align two antennas very accurately and only a true North Compass can achieve that (without celestial navigation techniques e.g. theodolites etc).
The yaw dampers that I have come across are purely to stop oscillation. It’s quite apparent in the back if the YD isn’t on in even a small Citation. There is no system to tell you about flying along with the ball off centre, other than the indication in the PFD which you can correct with the rudder trim.
Any airworthiness limitation will surely be about the traditional system to damp out oscillation in yaw, and the consequent dutch roll
