What does the centerline marking for taxiways consist of?

The centerline marking for taxiways is designed to provide guidance to pilots and ground vehicles, helping them navigate along taxiways safely. It consists of a solid yellow line. This solid yellow line clearly indicates the center of the taxiway, ensuring that aircraft stay aligned as they move to and from runways and other areas of the airfield. The use of yellow specifically denotes caution, which is appropriate for areas where pilots need to be especially vigilant while taxiing.

In the broader context of airfield markings, different colors and line styles serve specific purposes, and understanding these helps maintain safety and efficiency on the airfield.
