Re: 7E7 Flight Controls Electronics

Aha!  Finally an answer to my original question.

It is interesting how we can bounce around all over the place
in response to a simple question, dispensing advice, proclaiming
our preferences, and ranting our doctrine before someone
comes forward with exactly the information we were seeking.

Thank you Vernon.

I can now announce to my students that 7e7 will indeed be
programmed largely in Ada.  In fact, I am giving a briefing
to a group of engineers next Friday on the subject of software
practice in safety-critical environments, and this will be useful
information.  I also intend to introduce them to the ideas in
SPARK along with other good stuff.

Naturally, my briefing will not be biased toward Ada.
