Of even greater concern is the proliferation of off the shelf (read not approved) systems that are being used at some locations.
Not disputing what you are saying, but there is one other company that has CAR120 approval to provide MET services other than the BOM. They are Vaisala, and they have installed their systems at some locations around WA. Primarily mining sites I think. With the approval they have the ability to tap into the TAF system and transmit on AWIS/AWIB or ph.
Be interested to know which locations you are referring to
