The handbook provides comprehensive technical specifications for the visual aids used to guide aircraft, vehicles, and personnel. Key areas covered include:
The latest editions (such as the 3rd Edition, 2017 ) include enhanced guidelines on:
The aircraft apron (ramp) is the most dynamically congested area of any airport. Unlike runways and taxiways, which are linear and highly controlled, the apron is a shared space where aircraft, Ground Support Equipment (GSE), fuel trucks, baggage carts, and personnel converge.
Solid red or red/white striped lines bounding the aircraft stand. Ground equipment must stay outside this boundary until the aircraft is parked, engines are shut down, and anti-collision lights are turned off. Apron Markings Signs Handbook
When darkness or heavy fog reduces visibility, pavement markings alone are insufficient. Apron lighting adds a critical layer of safety.
The ultimate goal of standardized apron markings and signs is to reduce human error. The ramp is a high-stimulus environment with high ambient noise. Human factors engineering dictates that markings must be intuitive. Standardizing Situational Awareness

The handbook aims to promote worldwide commonality in markings, which improves safety for ground staff, pilots, and air traffic controllers by creating a predictable apron environment. Standardized Marking Colors The handbook reinforces ICAO color standards to distinguish between aircraft and vehicle zones:
Information signs feature either (direction/location info) or yellow lettering on a black background (location confirmation).
: Regulates vehicle traffic, service road boundaries, and pedestrian crossings. Apron lighting adds a critical layer of safety
: Continuous yellow lines that guide a pilot from the taxiway safely onto the designated apron parking stand.
🟡 : Used strictly for aircraft maneuvers, including taxiway centerlines, lead-in lines, and parking stand designators.
Signage on the apron reinforces pavement markings, offering high-visibility instructions during night operations or adverse weather. Apron signs are categorized by color and function according to International Civil Aviation Organization (ICAO) and Federal Aviation Administration (FAA) standards. Mandated Signs
Apron markings utilize specific color codes, line widths, and geometries to convey immediate messages to pilots and ground crews. Aircraft Stand Markings
