I am of the belief that the discussion on radio use here has missed the point. Once upon a time we had a Flight Radio Licence and with training to match and the then DCA/CAA took an interest and provided some standardisation in the training and standards. Of course that Licence, or was it a certificate(?) does not exist these days for reasons that seem to have been lost in history. CASA do not appear to provide any oversight or standardisation on radio procedures etc., and the result is that we now have different flying schools teaching radio procedures differently. I know one airfield where there are two flying schools that teach for example circuit procedures and radio calls differently. What hope do we have unless CASA start to provide some oversight and address standardisation. Part of the problem now is that the CASA flying inspectors (or whatever they are called now) have themselves many different ideas on how it should be done. (Due lack of experience perhaps?) Best CASA sort themselves out first…… until that happens we will not see any change.
