Runway Strip and Runway End Safety Area For the purposes of determining obstacles on the sides of the runway, the Runway Strip is referenced horizontally to the runway ends and vertically to the highest threshold on the facility. It extends 300 m (240 m beyond 60 m strip) from each runway end and 150 m on either side of the centerline. 150 m Not to Scale m 300 150 m
