Abstract : Since the digital computer first flew in an avionics system 25 years ago, the art has progressed from small very slow vacuum tube machines with limited memory to fast chip-based machines that not only do sensor processing but also integrate a variety of data sources into many capabilities--among others, navigation, sophisticated weapons delivery, programmed menu-displays to the air crew. As onboard computer hardware has proliferated, software inescapably has also. From a few hundreds of program words at the beginning, flight software is commonly many tens-of-thousands of words; frequently, a few hundred thousands; and in some cases, even a million. Thus, implementation and management of software resources has become a major problem area for military services. The paper explores dimensions of the issues as it now exists, suggests many positive actions under way, and proposes a direction in which the future may well move. It concludes that software will continue to be troublesome; progress will come slowly. (author)
