Thanks Cristiaan,
From the way you explain this autostabilisation it looks similar to the way a yaw damper works. With a rate gyro, ac current that is phase advanced, filtered and then amplified, but on all 3 axes?
Not being a real bright light on engineering I can see that such a system works to give ,,apparent'' dynamic stability..
Another question perhaps: Does concorde have real trim tabs? Or is it just an artificial feel unit that ,,changes the neutral point in the stick?
I've seen the (awesome, by the way) ITVV documentary but don't remember this being mentioned...
