It includes marking conventions, color and texture guidance, dimensional recommendations, aircraft stop-bar identification examples, and references to related FAA, FHWA, and ICAO publications. The document is intended for airlines, airports, ground handling providers, ramp operations teams, safety managers, and aviation facility planners.
