Thanks. I have read that report and can’t see how such an incident could be prevented by having more prescriptive dimensions on a ctaf . The incident once again shows the importance of remaining visually vigilant at all times.
May have been assisted by a NAS US style Unicom which all equivalent aerodromes in the US with RPT have. The Unicom would most likely advised of over transmissions if they occurred.
Shows that even with professional pilots that incidents can take place .
Always keep a good lookout. Even in C airspace under control. Remember Coolangatta !
