Handbook — Apron Markings Signs
This is where the handbook saves you from embarrassment. Most major airports use the A-SMGCS (Advanced Surface Movement Guidance) standard.
To be "solid," a handbook must specify physics.
| Marking Type | Minimum Line Width | Paint Type | Retroreflectivity (mcd/lux/m²) | | :--- | :--- | :--- | :--- | | Lead-In Line | 15 cm (6 in) | Waterborne epoxy | 150 (white) | | Stop Bar | 30 cm (12 in) | Thermoplastic (preformed) | 200 (white) | | Vehicle Walkway | 10 cm (4 in) | Solvent-based acrylic | 100 (yellow) |
FOD Note: Chipped or peeling paint is a FOD hazard. Markings must be repainted when retroreflectivity falls below 80% of original value (typically every 12–18 months in temperate climates; 6–9 months in heavy snow/sanding climates).
According to standard international handbooks (ICAO Annex 14), the apron is a rainbow of meaning. Here is the cheat sheet:

Note: To convert this into a "printed" handbook, you would add a title page, a revision log, and potentially diagrams of specific stand configurations (e.g., nose-in vs. angled vs. remote stands).
It sounds like you're referring to a well-regarded reference in airport operations and ground handling. The most commonly cited "good paper" for that title is actually:
"Apron Markings and Signs Handbook" – published by ACI (Airports Council International) and IATA (International Air Transport Association).

The Apron Markings and Signs Handbook , primarily published by the Airports Council International (ACI), is the global authority on standardizing the visual aids used in aircraft parking areas.
Standardization is critical because the "apron" (or ramp) is one of the most congested areas of an airport, where aircraft, ground vehicles, and personnel intersect in high-stakes environments. Core Purpose of the Handbook
The handbook provides a common language for airport operators to ensure safety and operational efficiency by:
Preventing Ground Collisions: Clearly defining aircraft paths and vehicle lanes to avoid "wing-tip" strikes and vehicle-aircraft accidents.
Optimizing Flow: Reducing pilot and driver confusion through consistent visual cues.
Regulatory Alignment: Ensuring local airport designs meet international standards set by ICAO Annex 14. Key Visual Components
The handbook categorizes visual aids into specific colors and styles to convey immediate meaning to pilots and ground crew: Aircraft Markings (Yellow):
Lead-in Lines: Guide the aircraft's nose gear onto the exact center of a parking stand.
Stop Lines: Precise points where a pilot must halt to ensure the aircraft is correctly positioned for passenger bridges and refueling. Safety & Service Lines (Red/White):
Equipment Restraint Areas: Painted boundaries (often red or white) that keep ground support equipment (GSA) away from the aircraft's engine and wing zones until the aircraft is powered down.
Tug Push-Back Lines: Specific paths used by tugs to move aircraft away from gates. Mandatory Signs (White on Red):
Used for locations where vehicles or aircraft must not proceed without explicit Air Traffic Control (ATC) authorization, such as runway holding positions. Information Signs (Yellow on Black / Black on Yellow):
Location Signs: Identify the specific taxiway or apron area currently being traversed.
Direction Signs: Indicate the path to specific concourses or parking stands. Strategic Management
The latest editions (such as the 3rd Edition, 2017) include enhanced guidelines on:
Technological Integration: Utilizing new paint materials and reflective technologies for better nighttime visibility.
Ground Handling Safety: Specific protocols for managing service vehicles around the newest generations of wide-body aircraft.
For detailed technical specifications, airport planners typically cross-reference this handbook with the FAA Aeronautical Information Manual for U.S.-specific regulations. Section 3. Airport Marking Aids and Signs

The Apron Markings and Signs Handbook is a vital resource published by Airports Council International (ACI) to standardize ground safety and operations worldwide. Currently in its third edition (2017), the handbook provides comprehensive guidance on visual aids specifically designed for the airport apron—the paved area where aircraft are parked, loaded, refueled, and maintained. Purpose and Scope
The primary goal of the handbook is to promote global commonality in airport markings. By standardizing how pilots and ground personnel interpret visual cues, airports can significantly reduce the risk of ground collisions and runway incursions. It serves as a critical supplement to international standards like ICAO Annex 14 and the ICAO Aerodrome Design Manual. Key audiences for this handbook include:
Airport Planners and Engineers: For the design and installation of new markings. Apron Markings Signs Handbook
Ground Operations Personnel: To ensure safe movement of service vehicles.
Pilots and Air Traffic Controllers: To maintain situational awareness during aircraft maneuvering. Key Components of the Handbook 1. Standardized Color Coding
Immediate visual recognition is achieved through a strict color-coded system:
Yellow: Dedicated to aircraft maneuvering, including taxiway and taxilane centerlines and aircraft stand markings.
White: Regulates vehicle traffic, service road boundaries, and pedestrian crossings.
Red: Indicates mandatory hold positions or prohibited entry areas.
Blue: Often reserved for service vehicle routes and specific parking zones. 2. Types of Markings

The Bottom Line: The Apron Markings & Signs Handbook isn't just a boring manual; it is a Rosetta Stone for the ramp. When you can read the pavement as easily as the PFD (Primary Flight Display), you stop being a hazard and start being a professional.
Stay safe out there, and keep the rubber on the painted lines.
Disclaimer: Always refer to your local airport’s specific AIP (Aeronautical Information Publication) and the current ICAO Annex 14, as markings can vary by country.
While markings are on the ground, signs are above or beside them. The Apron Markings Signs Handbook emphasizes that "Markings without Signs are Ambiguous."
The majority of handbook chapters focus on the Aircraft Parking Stand. This is the most congested space on the apron.
1. The Stop Position Marking
2. The Safety Zone (Red Envelope)
3. The Service Road Intersection
4. The Pushback Lane
Adopt authoritative national and international standards, tailor markings to your apron’s traffic mix, and maintain rigorous inspection and training programs to ensure apron markings effectively support safe ground operations.
