Having had a careful look at the AIP I believe this should be a “Lower than Standard Category I Operation” (that is "A Category I Instrument Approach and Landing Operation using Category I DH, with an RVR lower than would normally be associated with the applicable DH."). The aircrafts would need to be approved for CAT II and capable of a climb gradient of 5%, but the DH would be determined by baro altitude.

But let's say that I am wrong and this is a CAT II. There is no inner marker and the RA for a category C aircraft is 514'. Are GAs going to be performed the first time the radio altimeter reaches 514', which should be ~1.6 nm (~3 km) before the threshold? If that is the case the ILS CAT I and even the VOR procedure would let aircrafts get a bit closer to the threshold.

One final doubt: If the aircraft is capable of only a missed approach climb gradient of 2.5%, when do we start the GA? There is no RA for that case.
