Doc 9811 requires a FOD prevention program. When workers leave tools, cones, or broken bits of asphalt on the apron, they violate Section 9.2. Solution: Shadow boards and tool checks before leaving the work site.
For the airport operator, compliance with Doc 9811 means moving beyond the shelf copy. It means daily briefings, risk matrices, and "Stop Work" empowerment. For the individual worker—the man in the high-vis vest driving the sweeper—Doc 9811 is their shield. It protects them from entering a runway when an aircraft has short final, and it protects the aircraft from the debris the worker forgot to pick up.
Introduction: The Unseen Blueprint of Airside Safety When passengers look out of an airport window, they see a ballet of aircraft, tugs, baggage trains, and fueling trucks moving in astonishing synchronization. However, beneath this choreography lies a complex web of regulations. At the heart of the legal framework governing this movement is ICAO Doc 9811 .
Workers often install signs or lights that are not frangible. Doc 9811 is explicit: any object on the runway strip (up to 90m from centerline) that could cause damage to an aircraft must be frangible. Solution: Only use ICAO-certified hardware.
