..... had a system failure that required a mandatory Go Around very close to the Barometric minima.
So presumably it was Cat 1 or better at EPKK? Below Cat 1 you operate to a DH (Decision Height) based on RA (RadAlt) not to a Baro DA (Decision Altitude).
If the were indeed autolanding then they followed the correct procedure to go around for the failure - any more detail on what it was Stan?
