Interpretation

The 'Follow the Greens' operational trial is ongoing at Changi Airport, providing pilots with visual guidance on taxi routes. During the trial, taxiway centerline lights will be progressively turned on, and pilots must follow ATC verbal instructions when vacating the runway. The 'Follow the Greens' service is not available on the runway and rapid exit taxiway. Pilots must adhere to the green centerline lights and stop at the verbal clearance limit or when the red stop bar is illuminated. In case of ambiguity, pilots should stop and seek confirmation from ATC. The trial is scheduled from July 14 to September 30, 1100-2300.
