Go-around is a flight normal procedure and there should be no restrictions to that how often pilots executes go-around.
Some companies can be very easy on go-arounds and does it even well above the minimum go-around altitude as a company SOP.
Somewhile ago over here in Finland, it wasnt too unheardable that a plane made 2-3 go-arounds just to get over it and divert to another field!
Just a "couple" days ago here was snowing *alot* over the night and only one runway was in use at helsinki-vantaa airport... to make it better, the ILS was made inoperative as well by the snow!
So they had to do VOR/DME approach, which does not have a glideslope like ILS and the visibility was poor.
Many flights ended up doing a go-around or more and then diverted to an another field... or diverted even before.
Some were diverted to almost 200 miles away, when the closer airports ran out of space.
Was quite a busy day for EFHK ATC.
Suntracker,
How was the visibility at the time?
There are certain go-around minimums, based on CAT x classes, which are I II III and subversions. (ie CAT IIIb IIIc...)
CAT III is pretty much full auto-land, while CAT II and CAT I are manual flare & landing, but CAT II approach can be done on autopilot.
Each has different go around minimums, which by the 'runway' should be in sight or go-around should be executed.
CAT I 200ft, CAT II 100ft, CAT III 50ft.
If it had CAT II equipped and was coming to land, I can understand how it was low!
100ft is merely 30 meters....
