Right Avenger. Boeings, Airbus's, Embraers, Bombardier's, Gulfstreams, many aircraft are certified for RNAV operations. That doesn't mean the crews are though.
For commercial operations an operations specification must be obtained from the regulator before conducting any kind of RNAV approach, and that ops spec will not be issued unless the aircraft is certified and the crews are properly trained and checked on RNAV procedures.
What does any of that have to do with ILS, VOR or NDB approaches?
