Meggitt Avionics Air Data Computer (ADC) is a further development of our current in service High Integration Air Data Computer (HIADC+) instrument. It is a fully RVSM compliant primary Air Data Computer (ADC) that is based on a unit that has been in production and provided reliable front line service for many years. It has applications in all aircraft types including regional airliners, fast jets, and rotary wing aircraft as illustrated by the examples shown overleaf. Over 12,500 units are now in service globally in challenging Aero environments. ADC is a compact, but highly robust, unit that offers primary level accuracy performance together with extremely high reliability/stability and very low power consumption. In addition, the unit retains the ability for analogue and discrete signals, e.g. Altitude encoder output (for our HADS system), OAT, relay switches as well as dual independent ARINC 429 and MIL STD 1553 serial digital data communications.
