CAT.OP.MPA.305 Commencement and continuation of approach

SI 2024 No. 1290

1. For aeroplanes, if the reported VIS or controlling RVR for the runway to be used for landing is less than the applicable minimum, then an instrument approach operation must not be continued:

   1. below 1000 ft above the aerodrome elevation; or
   2. into the FAS where DH or MDH is more than 1000 ft above the aerodrome elevation.

2. For helicopters, if the reported RVR is less than 550 m and the controlling RVR for the runway to be used for landing is less than the applicable minimum, then an instrument approach operation must not be continued:

   1. below 1000 ft above the aerodrome elevation; or
   2. into the FAS where the DH or the MDH is more than 1000 ft above the aerodrome elevation.
3. If the required visual reference is not established, then a missed approach must be executed at, or before, the DA or DH or the MDA or MDH.

4. If the required visual reference is not maintained after DA or DH or MDA or MDH, then a go‑around must be executed promptly.

5. Notwithstanding point (a), in the case where no RVR is reported, and the reported VIS is less than the applicable minimum, but the converted weather visibility is equal or greater than the applicable minimum, the instrument approach can be continued to the DA or DH or MDA or MDH.
