Apron Markings Signs | Handbook

The Apron Markings and Signs Handbook , published by Airports Council International (ACI), is the definitive global guide for standardizing the complex visual language of airport aprons. Its primary goal is to harmonize markings worldwide to reduce ground accidents and improve operational efficiency in the busiest areas of an airfield. Core Content & Scope

• Edge Lines: Continuous lines define the edges of taxiways and parking areas.
• Safety Lines: On the apron, you will often see solid or dashed lines separating aircraft movement areas from vehicle service roads. These ensure that baggage carts and fuel trucks stay in their designated lanes.

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. Apron Markings Signs Handbook

Safety & Boundary Lines: Clear definitions for "no-parking" zones and equipment restraint areas to prevent collisions between ground equipment and moving aircraft. The Apron Markings and Signs Handbook , published
