Contains the FAA specifications for unlighted and lighted signs to be used on taxiways and runways. See also Engineering Brief 67: Light Sources Other than Incandescent and Xenon for Airport and Obstruction Lighting Fixtures.

This specification sets forth the FAA requirements for obstruction lighting equipment used to increase conspicuity of structures to permit early obstruction recognition by pilots.

This AC contains the specifications for airport light bases, transformer housings, junction boxes, and accessories. This AC is not intended to be a compilation of currently available product designs. It provides the basic standard requirements for critical dimensions and performance requirements to which all manufacturers must demonstrate compliance.

Contains the Federal Aviation Administration (FAA) standards for retroreflective markers for airport runways and taxiways. Version D changes Paragraph 3.4.2.2, Cylindrical Markers, to increase the marker diameter and surface area, and Paragraph 3.4.3.1, Mounting System, to clarify Type II marker mounting and tethering requirements.

Effective six months after the issue date of this AC, only equipment qualified per these specifications will be listed in AC 150/5345-53, Airport Lighting Equipment Certification Program.

Contains the FAA standards for the Precision Approach Path Indicator (PAPI) systems, which provides pilots with visual glideslope guidance during approach for landing.

Contains standards for the siting and installation of signs on airport runways and taxiways, including taxiway ending markers, location signs, runway distance remaining signs, mandatory hold signs associated with POFZ and CAT II/III operations, and many others.

Contains the FAA standards for markings used on airport runways, taxiways, and aprons. This AC cancels the Signs and Marking Supplement (SAMS).

This document is consolidated to include Change 1, dated November 17, 2010.

Provides guidance for using the standardized International Civil Aviation Organization (ICAO) method, called the Aircraft Classification Number – Pavement Classification Number (ACN-PCN) method, to report airport runway, taxiway, and apron pavement strength. Includes instructions for using the COMFAA program to calculate ACN values to determine PCN.

Also provides guidance for reporting changes to airport data that is generally published on Federal Aviation Administration (FAA) Form 5010, Airport Master Record, particularly those data elements associated with Gross Weight (Data Elements 35 through 38) and Pavement Classification Number (Data Element 39).
