In order to enhance the basic stability of the aircraft against Dutch roll, each autopilot system incorporates a yaw damper which is operative when the autopilot is engaged. In the event of failure of both dampers a third completely independent (Standby) yaw damper is available which may be engaged at any time. The Standby Yaw Damper drives the upper rudder surface under conditions where the ELRAT (Emergency Ram-Air Turbo-Alternator) is operating.
This was an Elliott design and was delivered for the very first flight of the VC10 from Weybridge as yaw damping was deemed critical.
