My apologies, triadic. I was trying - evidently unsuccessfully due to my lame facetiousness - to make the point that not all talk on the radio is necessarily helpful. That’s why I previously posted:
Radio, if used appropriately, will reduce the probabilities of aircraft with radios colliding with other aircraft with radios.
As you and poteroo have pointed out, broadcasting in IFR Martian doesn’t mean much to someone listening in VFR Venusian.
I think you’ll find that Bloggsie knows perfectly well that the section he quoted from CAAP 166 is not for the education of your or poteroo’s student pilots.
Lets just face it, the 20nm CTAFs will not work, it makes the system far too complicated.
Correct. Unfortunately, that increases the probabilities of them being introduced.
