'An ILS radiates a signal capable of use by a Cat I/II/III equiped/qualified aircraft/crew'
No it doesn't at Runway 35 at Cork for christ's sake!
.It doesn't matter if it was Neil Armstrong and Buzz f**king Aldrin in an Airbus 380, an approach to Runway 35 at Cork in less than 750m vis is illegal, no ifs, no buts! Runway 17 ILS is Cat II so there might be an argument there, 35 is Cat 1 ONLY. They made approaches to both runways; there is no question they were illegal, and at 350m RVR not just slightly either.
