Marconi Avionics Limited
Air data systems provide accurate information on quantities such as pressure altitude, vertical speed, calibrated airspeed, true airspeed, Mach number, static air temperature and air density ratio. The computer uses data from sensors such as the pitot-static system hence the ‘pressure’ connectors. The ADC is a key avionic system and forms part of the essential core of avionic sub systems required in all modern aircraft, civil or military.
Marconi Avionics, in common with other suppliers, made equipment for the EAP at their own cost in anticipation of orders for the Typhoon. Around 6 to 8 sets of equipment were made and all were put through the full evaluation/qualification tests.
