Advisory Circulars

Provides guidance on understanding, identifying, preventing, and mitigating alkali-silica reactivity (ASR) in fresh and hardened Portland cement concrete airfield pavements.

Provides recommendations for heliport design that apply to the construction, activation, and deactivation of heliports.

Because of the size of this document, it is available as a single file (see Complete) and as several smaller files (see Parts 1-4).

Provides recommended guidelines for maintenance of airport visual aid facilities.

Provides guidance, specifications, and standards for painting, marking, and lighting of vehicles operating in the airport air operations area (AOA).

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

Provides guidance for conducting predesign, prebid, and preconstruction conferences for projects funded under the FAA airport grant program.

Contains the specifications for containers designed to serve as airport light bases, transformer housings, junction boxes, and accessories. Provides the basic standard requirements for critical dimensions and performance requirements to which all manufacturers must demonstrate compliance.

Contains equipment specifications for light beacons which are used to locate and identify civil airports, military airports, seaplane bases, and heliports.

Contains a specification for constant current regulators used on airport lighting circuits and for a monitor that reports on the status of the regulator.

Contains the specifications for discharge-type flashing light equipment to be used for runway end identifier lights (REIL) and for an omnidirectional approach lightning system (ODALS).

Provides the specified manufacturing requirements for panels used for remote control of airport lighting and auxiliary systems.

Contains the FAA standards for retroreflective markers for airport runways and taxiways. See also Errata Sheet below.

Contains the FAA standards for power and control units for Land and Hold Short Lighting Systems.

Specifies the minimum requirements for an Airport Lighting Control and Monitoring System (ALCMS). The ALCMS simplifies the control and monitoring of lighted visual aids and enhances airport safety. The basic function of the system remains the same whether for a general aviation airport that supports only a few operations in a day or a large commercial airport that caters to hundreds of operations on any given day.

Effective six months after the issue date of the AC, only that equipment qualified in accordance with this specification will be listed in accordance with AC 150/5345-53, Airport Lighting Equipment Certification Program. Airports that have previously installed an Airport Lighting Control and Monitoring System (ALCMS) will not be required to install a new system after the effective date of the AC.
