A friend mentioned being a passenger during a commercial aircraft landing at Taiwan's Penghu Airport (MZG, RCQC) where they had almost touched down but had to abort and keep going due to sudden wind event causing "scary motion". They circled back around and landed minutes later uneventfully.

I'm sure there are standard aviation terms for these but I don't know them.

I mentioned that these happen somewhat regularly especially at certain airports and that one of the first thing student pilots learn is how to do touch-and-go's.

Now I'm curious if there are rough numbers for how often this happens per year and if airports like Penghu's see these more frequently? Something like one out of every 100 days an aircraft has to come around and try again at that airport, or one landing out of 10,000 or similar type of summary statistic.

    $\begingroup$ I can't find anything particular about Penghu, but the FAA has published some numbers in this PDF on page 12: "average go-arounds across all Core 30 airports were 0.3 percent". $\endgroup$

    $\begingroup$ 0.3% doesn't seem like much until you realize that 0.3% of 11 million flights is 33,000 go-arounds (at the 30 busiest airports only) which is 90 per day, or 3 per day per airport, on average. So, about 1 every 8 hours at the 30 largest US airports. $\endgroup$

    $\begingroup$ Hey, @Bianfable, between you & me, I think we've got an answer (well, sorta...). You did the hard digging, I just did some math - feel free to write it up and you'll get my vote. $\endgroup$
