Also marked: "CONTROLLER, FLIGHT, AUTOMATIC PILOT". The control panel consists of a manoeuvring controller, a rotary mode selector switch, a three position autopilot damper engage Switch and a two position toggle switch for engagement of height Lock’s. The mode selector switch has five positions: MANUAL; HDG; LOC/VOR; GS AUTO and GS MANUAL.

The BAC 1-11 AFCS, like that in the VC10, was based on the well proven Bendix PB-20 Autopilot and was designated the Series 2000 AFCS. New features over the PB-20 system include separate pitch and azimuth control computers, a modular Air Data Sensor and a range of units specifically designed for autoflare and autolanding.

Each unit in the BAC 1-11 AFCS is built to a common configuration with circuit modules arranged in stacks either side of the chassis. The stacks are connected by plugs to a mother board and are physically separated into ‘command’ and ‘monitor’ functions to preclude common failures. The computers are entirely solid state and there is a high degree of built-in-test. Self-monitoring techniques and multiple channel redundancy are used to give automatic failure survival in approach and cruise flight.
