Since there was no separate 'auto-rudder engage' control switch (the function was permanently active), and it was only mentioned very much in passing during training, some pilots were not even aware it existed.......
But this was the beauty of Concorde, there was so much in the way of automatic protections and enhancements 'built in' that one could quite quite reasonably take it all for granted. That was definately true for most of the AFCS computation. (It's all your fault ChristiaanJ for helping to design such a great system
).
And now we have CliveL joining this thread, one of the true 'fathers of Concorde', it can only become even more fascinating with his inputs here.
(BTW, this thread has now passed 100,000 viewings in just four short months
).
