Lighting Systems Group The mission of the Lighting Systems Group is to provide research, development and acquisition for safe, efficient, and reliable ground-based navigational and landing systems. Approach Lighting System Improvement Program The Approach Lighting System Improvement Program (ALSIP) was primarily established to replace older rigid structure approach lighting systems with low impact resistant structures. In the late 70’s the National Transportation Safety Board recommended the FAA expedite the retrofit of approach lighting systems structures with frangible materials and fittings. |
