CS ADR-DSN.M.665 Runway lead-in lighting systems

(a)Applicability: A runway lead-in lighting system should be provided to avoid hazardous terrain.

(b)Location and positioning

(1)A runway lead-in lighting system should consist of groups of lights positioned:

(i)so as to define the desired approach path. Runway lead-in lighting systems may be curved, straight, or a combination thereof; and

(ii)so that one group should be sighted from the preceding group.

(2)The interval between adjacent groups should not exceed approximately 1 600 m.

(3)A runway lead-in lighting system should extend from a determined point up to a point where the approach lighting system if provided, or the runway lighting system is in view.

(4)Each group of lights of a runway lead-in lighting system should consist of at least three flashing lights in a linear or cluster configuration. The system should be augmented by steady burning lights where such lights would assist in identifying the system.

(c)Characteristics: The flashing lights and the steady burning lights should be white.
