What is the primary function of surface markings on taxiways?

The primary function of surface markings on taxiways is to guide aircraft and vehicles along safe paths. These markings help pilots and ground vehicle operators understand their location on the airfield and facilitate safe navigation to and from runways, terminals, and other facilities. By using standardized colors and symbols, surface markings provide crucial information that enhances situational awareness and helps prevent accidents on the airfield.

Surface markings are designed to convey specific types of information, such as boundaries of taxiways, holding positions, and directional guide lines. The clarity and visibility of these markings are essential for maintaining safe operations on the airfield, especially during low visibility conditions.

While other aspects such as indicating parking spots, showing restricted areas, and providing directions to terminals are also important components of airfield operations, they are not the primary role of surface markings on taxiways. The main purpose remains focused on guiding aircraft and vehicles safely along the established paths.
