The worst thing on the radio by a country mile though is people doing RNAV approaches into CTAFs and giving their calls by relation to a series of letters. How is Joe Bloggs in his 172 doing circuit training going to not what on Earth Captain Embraer is doing?
Captain Embraer should read CAAP 166:
Pilots who wish to conduct practice instrument approaches in VMC conditions should be particularly alert for other aircraft in the circuit so as to avoid impeding the flow of traffic.
IFR pilots should give position reports in plain English to be easily understood by VFR pilots who generally have no knowledge of IFR approach points or procedures, e.g. positions should include altitudes and distance and direction from the aerodrome.
Providing position reports to VFR pilots that contain outbound/inbound legs of the approach or RNAV fixes will generally be of little assistance to establish traffic separation.
