Surface markings on the apron are color-coded and geometrically designed to separate aircraft from ground vehicles and define safe parking boundaries. Aircraft Lead-in Lines (Yellow)
: Continuous double yellow lines indicate the edge of a taxiway next to an unusable shoulder, while dashed double yellow lines denote an edge bordering a usable area like an apron. Vehicle Roadway Markings
: High-visibility lines that contrast with aircraft stand markings to delineate safe work zones from aircraft movement areas. Taxiway Edge Markings Apron Markings Signs Handbook
Effective apron markings and signs offer numerous benefits for airports, including:
This core practical section provides example layouts and a complete maintenance lifecycle guide: Surface markings on the apron are color-coded and
Every individual with apron driving privileges must pass a ramp safety course. This training ensures drivers can instantly read apron signs, respect equipment restraint lines, and correctly yield at zipper crossings.
: Facilitate unobstructed routes for emergency vehicles during incidents. Key Markings and Signs Taxiway Edge Markings Effective apron markings and signs
: Markings that delineate areas intended for use by ground vehicles, GSE, and other servicing equipment, ensuring safe separation from aircraft movements.
: Countries including Canada, Australia, and the United Kingdom create their own guidance based on ICAO, adapted for local operational needs.
Retroreflective markings typically use glass beads to reflect light from aircraft headlights and apron lighting back toward the pilot. For taxiway and apron markings, materials may include retroreflective marking tape or thermoplastic with embedded glass beads.
