I'm confused by this comment, can you please explain it in slightly
different words?

Wow - I Had no idea there was a process in place in your department.

Are you sure? Even permanent ones? I thought BAE *and* AeI were having
problems recruiting good, permanent Ada engineers because:

1) They don't pay enough
2) Many people don't want to do Ada!

That's good - we never got *any* training on the rig team!

That depends on how flexible you are, and how much OO you want to use.
Looking at it the other way, I don't think it would be difficult to do
avionics in C++ if you already know Ada properly - and it will
certainly be more reliable if you have to use C++, to use Ada trained
developers to do the job than those who have only ever used C/C++
based languages!
