---- but don't answer clear and direct questions you don't like
Arm,
I don't particularly "like" or "dislike" your questions, I just regard them as a nonsense.
As incomprehensible as it may seem to you, you apparently being a product of the Australian "system", there is no one "correct" answer to the questions, to which you have demanded answers.
As to who would say and do what, when, in and around an airfield in Class G, doesn't that entirely depend on the circumstances, and ,while we are at it, I see little difference between IFR and VHF equipped VFR flights?
Tootle pip!!
PS: I suppose you realise that the "The Australian Way" (do-it- yourself ATC) as above has been subject of considerable scrutiny/study over the years (and not "just" by Dick, but major consulting orgs., with seriously heavyweight credibility, hired by AU Government entities) and been found to NOT be the optimum in minimizing the risks of operation in G.
