Coming from a european "high performance aircraft" point of view, I can
say Ada has even replaced older languages in the last years and at least
on the
techincal side of things there is no change of this trend insight.
Actually the 
Ada minded people are having an easier time now because 
a.) compilers have become more reliable and performant
b.) experince in implementing real time has shown the benefits of Ada
c.) the systems have become alot more complex 

For example the X-31 flight control system was done in Jovial. However
if the
program should ever be reactivated it is very likely that the fcs will
be done in
Ada.
