CS ADR-DSN.M.685 Runway end lights ED Decision 2017/021/R (a) Applicability: Runway end lights should be provided for a runway equipped with runway edge lights. (b) Location and positioning: (1) Runway end lights should be placed on a line at right angles to the runway axis as near to the end of the runway as possible and, in any case, not more than 3 m outside the end. (2) Runway end lighting should consist of at least six lights. The lights should be either: (i) equally spaced between the rows of runway edge lights; or (ii) symmetrically disposed about the runway centre line in two groups with the lights uniformly spaced in each group and with a gap between the groups of not more than half the distance between the rows of runway edge lights. (3) For a precision approach runway Category III, the spacing between runway end lights, except between the two innermost lights if a gap is used, should not exceed 6 m. (c) Characteristics of runway end lights: (1) Runway end lights should be fixed unidirectional lights showing red in the direction of the runway. The intensity and beam spread of the lights should be adequate for the conditions of visibility and ambient light in which use of the runway is intended. (2) Runway end lights characteristics on a precision approach runway should be in accordance with the specifications in [CS ADR-DSN.U.940](#_DxCrossRefBm151830505), Figure U-12. (3) Runway end lights on a precision approach runway should be in accordance with the chromaticity specifications in [CS ADR-DSN.U.930](#_DxCrossRefBm151830859) and Figure U-1A or U-1B, as appropriate.
