In general connection with this thread, I am aware that
yaw-damping is one of the functions of the digital flight
control system on fly-by-wire aircraft such as the A320
and its successors and the B777. However, Dutch roll is
a vice of any delta-winged aircraft. Presumably, automatic
yaw-damping was achieved in pre-FBW days by a simple
analogue system (possibly part of the autopilot)?

I'm guessing. Does anyone have any definite information?
