What does the movement area boundary marker consist of?

The movement area boundary marker is essential for defining the transition between different areas of an airport, particularly where movement areas for aircraft and non-movement areas operate. This marker consists of a single solid yellow line paired with a single dashed yellow line. The solid part indicates the boundary where aircraft are required to exercise caution when transitioning to or from different operational zones. The dashed line serves as a visual cue that aircraft may cross it, but only with proper clearance and attention to safety protocols. This dual line system effectively communicates the rules and operational requirements in the vicinity of taxiways and runways, ensuring safety and clarity in airport operations.
