What is the appearance of non-movement area boundary markings?

The appearance of non-movement area boundary markings is characterized by two dashed and two solid lines. This specific configuration is used to clearly delineate areas on airport surfaces where aircraft are allowed to move freely versus areas where they are restricted from entering without authorization. The solid lines indicate the actual boundary where movement is not permitted, while the dashed lines serve as a visual guide to signify that vehicles and aircraft can cross those lines but should do so with caution and awareness of the designated non-movement area.

In practice, this design is essential for maintaining safe operations on the airfield, as it helps ensure that personnel and vehicles remain in the areas where they are allowed, thereby reducing the risk of accidents in a busy airport environment. The distinct combination of dashed and solid lines creates a clear and effective visual cue for pilots and ground personnel, enhancing overall situational awareness.
