Per AC 150_5340_30d,
4.3. TAXIWAY CENTERLINE, subsection c: Longitudinal and Lateral Spacing. The lights are spaced longitudinally per Table 4-1 for minimum authorized operations above and below 1,200 feet (365 m) RVR. Fixtures should be installed so that their nearest edge is approximately 2 feet (0.6 m) from any rigid pavement joint. Allow a tolerance for individual fixtures of ±10 percent of the longitudinal spacing specified to avoid undesirable spots. However, a tolerance of ±2 ft (0.6 m) is allowed for fixtures spaced at 12.5 ft (4 m). Displace centerline lights laterally a maximum of 2 feet (0.6 m) (to the nearest edge of the fixture) to avoid rigid pavement joints and to ease painting the centerline marking. Apply this lateral tolerance consistently to avoid abrupt and noticeable changes in guidance; i.e., no "zigzagging" from one side of the centerline to the other. RFI 00017 answer directed the contractor to locate Taxiway “P” REL cores 12” off of Taxiway Centerline Joint. This lateral displacement places the edge of the REL fixture a maximum of 2 ft. per section 4.3c, above. In accordance with the directive to avoid “zigzagging”, the lateral displacement was applied not just to the fixtures impacted by the offset pavement slabs (R2D048 – R2D052), but to the terminal light at the 21R Centerline as well. ************************************************** ******* I'm in the middle of writing a design rationale for some Runway lighting work at Detroit Metro, and avoiding it by reading the forums... not very exciting. |
