I'm waiting to get shouted down, but here goes. What the Casa brochure Be Seen Be Heard Be Safe says as an example call is this.
"Parkes traffic, C172, ZTQ one-zero miles
north inbound on descent through 4,200,
estimating circuit at three six, Parkes."
The first three bits are simple: Where you are calling, "traffic", what you are and who you are.
The next bits are complicated.
1. Distance away.
2. Bearing (from their perspective).
3. What you are doing overall: "inbound" or "overflying".
4. What you are doing for altitude, if anything: climbing, descending.
5. Current altitude.
6. "Estimating"
7. What you are going to do, again: "circuit" or "overhead"
8. "At"
9. Time.
Then, the place is simple.
If you were really supposed to say who you were talking to, who you were, where you were, what you were doing, time and place again, you would say.
Parks traffic, C172, ZTQ, 10 miles north 4500 feet, descending, inbound for circuit (or not "circuit" because if you are inbound, a full stop is assumed) estimating at 36, Parks. Which I think would be better. But improving on the rules is the last thing that I would want do do.
What is going on? Is there some reason it is like this? I don't want to improve on the rules. Saying what people expect you to say, when they expect you to say it, is much more important than improving on the standard procedures in one's one idiosyncratic way.
