I'd say glass cockpits are pretty new. At least for civil aircrafts. And 
my guess is that most would use something like scade.

I'm not associated with them in any way and the price-tag for systems 
like these would likely be in the same range as the paychecks for the 
managers at GM or Leeman Brothers. Perhaps combined. It would anyway 
probably be cheaper than developing your own solution.
