Air Traffic Control (ATC) Basics Block 1 Practice Test

Taxiway centerline lights are green. These lights are designed to provide guidance to pilots as they taxi on the airport's taxiways. The green color is easily recognizable and helps to improve visibility, especially in low-light conditions or at night. This bright color assists pilots in following the designated taxi routes and enhances safety on the ground by marking the center of the taxiway. It's important to note that other colors are used for different purposes: blue lights indicate the edges of taxiways, while red lights are commonly used to indicate a stop bar. However, for the specific function of indicating the centerline of taxiways, green lights are the standard.
