Pierre what you suggest has some merit but with the mental state of airport management in this country they would simply see it as a quick first step to CAS around their precious "International" airports. Until something is achieved to update and integrate training for all concerned with aviation and something done to rid us all of the "us and them" attitudes then nothing except full CAS will satisfy the airport operators. Incidentally what status do you expect to confer on the "MATZ" as well as the ATZ?
