Interpretation

The approach lights for runway 12 have been reduced to basic lights due to the replacement of halogen lights with LED lights. Fixed-wing aircraft cannot approach runway 12 if the runway visual range (RVR) is less than 1000 meters, and rotor-wing aircraft cannot approach if the RVR is less than 750 meters.
