You call it 'normal'.

So how many times a day does it happen - on average - in a large airport?

Comments

0.39% of arrivals at core 30 airports result in a GA. So 1-3x/day average. Not all due to spacing though, go arounds also occur due to an unstable approach, wind shear, animal on the runway, etc. If pilot or ATC is not 100% sure of a safe landing, then they GA.

0.39% of anything is not 'normal'!

It happens everyday, that seems like a reasonable use of “normal” to me. Of course it’s a small overall percentage of flights, it would be inefficient to have a go around every other landing and something would be changed. But it happens, it’s not newsworthy, and it’s not a cause for concern.

Каково это — работать на ферме троллей?

I wouldn’t call the BPL Boylston street building a “troll farm,” it’s far too nice for that… We’re from the same city dude. I assure you that having some aviation knowledge does not mean that I support Trump, Musk, or Russia. But I’d rather fight misinformation with actual facts, not fear mongering.

Just a hunch. Do you have any idea of how unusual an event which occurs 0.39% of the time is?
