Is the Maneuvering Area Delimitation (MAD) line the separation between a controlled and uncontrolled surface?

The Maneuvering Area Delimitation (MAD) line serves as a critical visual marker within the airport environment, distinguishing between areas where aircraft have a defined level of operational control and those where they do not. Specifically, the MAD line delineates the controlled maneuvers of aircraft from uncontrolled zones. This is essential for maintaining safety and organization on the airside, allowing for effective management of all aircraft movement in the vicinity of runways and taxiways.

When aircraft operate in areas on the controlled side of the MAD line, they are subject to air traffic control instructions and regulations that ensure safe operations. Conversely, zones on the uncontrolled side allow for different procedures and do not have the same level of oversight. Understanding this distinction is crucial for airside vehicle operators, as it directly impacts their compliance with regulations and their situational awareness while maneuvering on the airport's surface.

Therefore, identifying the MAD line as a separation between controlled and uncontrolled surfaces is fundamental to the safe operation of vehicles and aircraft within the airport's airside environment.
