Is there a CAT 1 ILS on this runway? If so what is the DA & RVR? The only parameter that meets CAT 2 is <550m RVR. It is an odd ball. CAT 2 ground installations have other specifications than a CAT 1. It seems a lot of bother for 100m reduction in RVR. However, the CAT 1 RVR may be much higher than 550m.
