Standby Yaw Damper
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 Damper drives the upper rudder surface under conditions where the ELRAT (Emergency Ram-Air Turbo-alternator) is operating.
The unit has the code 'V.A.A.S 227 (ET)' on it. This was an Elliott design and was delivered for the very first flight of the VC10 from Weybridge as yaw damping was deemed critical. This first unit was damaged on test before flight but was rebuilt in record time by the engineers at Borehamwood.
