Hi Jim,
Not exactly. There was a big discussion about reusing the research
prototype code, and the FAA subsequently made it clear that they did *not*
want us to reuse that code. The issue was safety. The prototype code was
research-grade, and was neither intended nor designed for full-scale
worldwide operational use in a safety-critical system carrying millions of
civilians. The plan was to use the existing code as a particularly
detailed form of documentation, and to develop the operational code from
scratch using the full-blown formal safety-critical software design and
development process, with redundant and mutually-suspicious components.
The whole nine yards.
Has anybody an example of a recent FAA RFP/SOW either asking for or
permitting Ada? I think that's the key question.
Joe.
