CS ADR-DSN.M.625 Approach lighting systems ED Decision 2016/027/R (a) The safety objective of the approach lighting system is to provide alignment and roll guidance, and limited distance-to-go information to enable safe approach to a runway. (b) Non-instrument runway Applicability: Where physically practicable, a simple approach lighting system as specified in [CS ADR-DSN.M.626](#_DxCrossRefBm1800047719) should be provided to serve a non-instrument runway where the code number is 3 or 4, and intended for use at night, except when the runway is used only in conditions of good visibility, and sufficient guidance is provided by other visual aids. (c) Non-precision approach runway Applicability: Where physically practicable, a simple approach lighting system specified in [CS ADR-DSN.M.626](#_DxCrossRefBm1800047719) should be provided to serve a non-precision approach runway, except when the runway is used only in conditions of good visibility or sufficient guidance is provided by other visual aids. (d) Precision approach runway Category I Applicability: Where physically practicable, a precision approach Category I lighting system as specified in [CS ADR-DSN.M.630](#_DxCrossRefBm1800047718) should be provided to serve a precision approach runway Category I. (e) Precision approach runway Categories II and III Applicability: A precision approach Category II and III lighting system as specified in [CS ADR-DSN.M.635](#_DxCrossRefBm1800047717) should be provided to serve a precision approach runway Category II or III.
