Since this IS TechLog, may I ask a question?
Large flocks of birds DO show up on radar. IIRC ground-based meteo-type radars are even used regularly to follow bird migration.
So my question is: what's the minimum range setting on a typical aircraft Wx radar? And is that setting ever used at lower levels?
It will never catch that one heron just after take-off. But it might just catch that huge flock of Canada Geese at 5000 ft, or the vultures at 10,000 ft...
I'm only a radar geek. I just wondered.
