Wirbelsturm, just saying, CAT IIIB approach, NDH, rvr falls below minima, what do you do? or, standard ILS CAT I....stunning day and visibility...1500ft you see a mate lining up and he broke the nosewheel steering blocking you...ATC calls for a go around...do you fly till 200ft RA close to the unlucky guy before hitting the magic button?
