IGH,
The airport cannot comment on the technical qualification of the aircraft. It can only declare it's current qualification. The use of Auto-coupled is none of the airports business. What about aircraft qualified for HGS 111A they must not use the Autopilot but are qualified to operate to Cat III minima.
In the end the crew must ensure the 3 pre requisites of Airfield, Aircraft and Crew are all qualified to the appropriate capability and if so commence/continue the approach if the weather allows.
