There has been a rapid growth in the use of digital avionics computers over the last decade. The impact of the computer on the design and development of any system and on the certification of high integrity systems is out of proportion to its size. The source of this impact lies in the introduction of programmability into the systems. Introducing programmability has two effects. First, it introduces an activity and an end product (programming and programs) which are implicit in an analog system but impossible to identify independently. The second effect of programmability is to complicate the failure characteristics of the system. Both effects of programmability must be clearly recognized and properly dealt with in engineering digital systems. Each is discussed briefly in this paper.
