The following documents are continually revised and contain multiple sections, to simplify presentation of material. These status lists are available for aviation users in order to denote qualified U.S. airports and runways for Category I (CAT I), Category II (CAT II) and Category III (CAT III) Instrument Landing System (ILS) operations. The lists also contain information for foreign CAT II and CAT III airports and runways approved for U.S. air carriers.
The Restricted U.S. facility list and foreign CAT 2-3 airport list still "require prior AFS-400 approval" and must be listed on this website before U.S. air carriers can be authorized the operation. Once listed, and upon completion of autoland demonstrations as described in AC 120-28D, Principal Operations Inspectors may approve their operator via Operations Specifications, Management Specifications, or Letter of Authorization.
