Computer Acceleration Control
Modification Record 1
The British Army ordered over 100 Westland Aerospatiale Lynx for a variety of roles, from tactical transport to armed escort, antitank warfare , reconnaissance and casualty evacuation. The Lynx AH.1 first entered service with the Army Air Corps (AAC) in 1979.
The Acceleration Control Computer forms part of the Mk34 AFCS system which provides attitude stabilization in the pitch and roll axes. Stabilization demands are fed to limited authority series actuators which in turn drive the main powered flying controls. In the yaw axis the system operates as a yaw rate damping system to stabilise the aircraft during manual and automatic flight. The Acceleration Control Computer contains the electronic modules and accelerometers required for the collective stabilisation functions and lateral acceleration computing for augmenting yaw stabilisation.
These units were repaired down to board and component level at DARA Fleetlands. (Input from Nick Petty who recognised his handwriting on this unit which he repaired in 1994).
