3 Terms and definitions

The terms and definitions defined in GB/T 7256.1-2022 and the following apply to this document:

Installed in the runway approach lighting system, it flashes unidirectionally or omnidirectionally from far to near in the approach direction in a dynamic rolling mode to provide clear approach heading, a lighting system used to make the runway threshold eye-catching or to reduce the impact of surrounding non-aeronautical ground lights:
