Definitely.

At Barco we design the displays down to the layout of the boards.
Most of the ASICs and processors are COTS, but not much more.

Yes.  We use Ada for almost everything.

Certified to what level?  When we do DO-178B level A or B we certainly
do not use Windows XP.  If it's level E then it is not life-critical,
and the only potential problem is customers complaining they've paid
millions in development contracts just to get the blue screen of
death :)
