Purpose of This Order.

This order lists the minimum requirements for evaluation and approval of ground facilities supporting Category (CAT) I approaches and CAT II approaches to runways which do not meet all performance or equipment requirements of a U.S. Standard or International Civil Aviation Organization (ICAO) Standard, and for all CAT II and CAT III approaches. Specifically, this order addresses the following items:

a. Lists the minimum requirements for CAT II and III operations at various facilities. The Federal Aviation Administration (FAA) criteria for CAT II and III operations meet ICAO CAT II and III standards.

b. Lists the minimum requirements for CAT I approaches using a Runway Visual Range (RVR) minimum of 1800 feet and a decision altitude (DA) of 200 feet, and CAT I approaches using an RVR minimum as low as 1400 feet and a radio altimeter (RA) decision height (DH) as low as 150 feet height above touchdown (HAT) at runways which do not have touchdown zone (TDZ) and/or runway centerline (RCL) lighting.

c. Lists the minimum requirements for CAT I approaches using an RVR minimum as low as 1400 feet and an RA DH as low as 150 feet HAT on suitable instrument landing system (ILS) equipment at runways that do not have TDZ and/or RCL lighting.

d. Implements FAA policy regarding Localizer (LOC) performance with vertical guidance (LPV) approaches and a Ground Based Augmentation System (GBAS) Landing System (GLS) with a DH of 200 feet and visibility minimums of RVR 1800 to airfields with reduced lighting.

e. Lists the minimum requirements for CAT II approval to runways, which do not meet the equipment requirements of a U.S. Standard or ICAO Standard.

f. Implements FAA policy regarding CAT II approach operations with an RVR minimum of 1000 feet to runways, which meet U.S. and ICAO Standards for CAT II equipment, performance, and lighting.
