I thought I'd share this but in a separate thread as it's a specific event or type of event that I'd like to learn from, rather than directly about mandatory EC or not.
The other day I was joining overhead to land at a FISO aerodrome busy with circuits. But at the time the radio was fairly quiet. I didn't hear anything about any aircraft departing. I was looking out for aircraft converging with me as I approached the numbers at overhead join height approximately parallel and above the base leg. As I descended on the dead side, I carefully looked and observed nothing on the runway and nothing on the climbout.
When I was crosswind the FISO alerted me to being "inside" another aircraft. And there it was. The FISO then alerted the other aircraft of me.
I assume it had just departed, rather than just joined crosswind, and had only just climbed into my view. Did I miss the radio call of it departing? Or was it just really slow climbing out, so I didn't consider its earlier announcement of taking off relevant to me? Why didn't I see it? I have a PilotAware Rosetta and also broadcast ADS-B out. I assume it probably had nothing GNSS-EC-wise because at no point did it appear, even when in direct line of sight to my receiver.
I don't think that "the distance between aircraft as well as their relative positions and speed have been such that the safety of the aircraft involved may have been compromised" so it doesn't qualify as an airprox.
However, it was, in general, a MAC risk, because had their climbout been a little steeper, or my crosswind a little wider, they would have climbed into me. I'm very grateful for the FISO callout (though I assume at that stage the other aircraft would have seen me before turning).
I welcome the learning opportunity here. But this is why I am starting from the POV that I want mandatory EC - because I try to listen, and I try to look out, and it doesn't work. This isn't the first time either. The first time was when I was a student, and my ridiculously high hours instructor was surprised - and in fact that was in approximately the same spot, under the same circumstances (ie. on crosswind following an OH join).
