A cut-glass tumbler with etched wording to commemorate delivery of the 1,000th Tornado Pitch Computer in 1988.The occasion was marked by a flypast of two Tornado IDS aircraft from RAF Marham. Interestingly the lead aircraft was piloted by Squadron Leader Tim Southan who had been an Apprentice at the Company between 1965 and 1970 before leaving to join the RAF.CSAS:
The command stability augmentation system: (CSAS) is by its very nature one of the most complex systems on Tornado. Hardly detectable in the cockpit, the CSAS keeps the ride comfortable at all speeds and altitudes, and makes the aircraft controllable throughout the flight envelope.It is a “fly-by-wire” system with autostabilisation, the pilot’s control demands being signalled and augmented electrically to maintain good handling qualities over the wide flight envelope. In the pitch axis, the fly-by-wire system has mechanical reversion. The system is triplicated and includes triplex computing, triplex rate gyros, triplex position sensors and a triplex accelerometer, with quadruplex outputs driving quadruplex electrohydraulic actuators. These “fly-by-wire” actuators were originally designed by Marconi-Elliott Avionic Systems Limited and have now been integrated by Fairey Hydraulic into the aircraft’s main hydraulic power control units.
The CSAS electronics is packaged in two units, the pitch computing circuitry being housed in a single computer and the roll, yaw and spoiler circuitry in a similar computer.
The system uses very high-precision analogue circuitry to provide accurately- matched control lanes, and a unique voter monitor design which reduces transient effects, due to system failures, to a low level and is so designed also that nuisance warnings are rare.
Marconi-Elliott Avionic Systems Limited has design leadership on the CSAS programme, but shared the production with Bodenseewerk Geratetechnik.
The system was designed to Specification SP-P-41600.
