What is the purpose of the Enhanced Taxiway Centerline?

The Enhanced Taxiway Centerline serves an essential function in aviation by providing a clear visual cue to pilots that they are nearing a runway hold position. This area is crucial for maintaining safety and preventing potential runway incursions, as it indicates to pilots when they should prepare to stop or exercise caution when taxiing in proximity to active runways. The enhanced centerline is typically marked with a solid line followed by a dashed line, giving pilots a distinct reference that delineates the threshold at which they must be especially vigilant about runway activity. This visual aid is vital for improving situational awareness and ensuring safe operations on the airfield.
