1.3 This initiative forms part of an operational evaluation and optimisation exercise, undertaken to assess system effectiveness, operational reliance, and alignment with current aircraft and runway performance.
2 TEMPORARY DEACTIVATION OF LIGHTING
2.1 As part of this structured evaluation, all RETILs along Runway 02C and 20C have been deactivated and the circuits isolated for the duration of the trial period.
