Captain Bloggs, the message was a bit unclear. Tankengine was on the money.
The CP encourages pilots to make radio calls as required to ensure safe operations. The method of summing it up is to ask "Who are you talking to? And Why are you talking?"
So if you are broadcasting and there is other traffic, then keep to the point of the radio broadcasts (which is to establish situational awareness - not to organise after works drinks or to clog up the airwaves with - turning downwind, mid-downwind, late down-wind....).
If you broadcast, and there is no other traffic, then keep to the minimum - joining circuit, turning base, (before departure) taxi-ing, entering an active runway.
