Go Around Frequency
I did a stint as a reasonably regular business traveller in Europe for a few years, notching up about 250 flights as SLF. Of those, two were go-arounds, one at Dublin (coincidentally), the other at Berlin Tegel, so 0.8% from that small sample. Both were as a result of an active CuNim directly over the field. In both cases I was rather glad the driver did what he did and went round - I certainly wouldn't have fancied attempting the landing. But then I'm a big girl's blouse....
