AIRBUS and ATR System Architecture and Specification
Design diversity is widely used on board of the aircraft for which AEROSPATIALE has the design responsibility. Indeed, all the aircraft currently in production, and all the aircraft designed since the end of the 70’s are using dissimilar software. The current (mid-1986) number of such aircraft is 120 AIRBUS, and 20 ATR.42. A lot of different functions are computerized with dissimilar software. The principal ones are the automatic and electric flight control systems (“automatic pilot” and “Fly by Wire”), and the flight instruments.
