With respect to ILS capability, couldn't LSA be capable of Lower Than Standard Category I ops? Assuming that the 'new' ILS installations are of the latest technical standard, LSA seems to comply with the necessary requirements with the exception of a 'Full Approach Lighting System'. However, also assuming that the existing CL 4 Bar complies with the 'Basic Approach Lighting System' then LTSC 1 ops to 200ft DH/500m RVR should be possible, at least on Rwy 23?
