Chapter 6 of ICAO Annex 14 Volume I “Aerodrome Design and Operations”, ICAO regulates obstacle lighting’s photometric characteristics. Some recommendations are clarified about how to deploy obstruction lights for different heights of structures. Obstruction lighting’s intensity characteristics and recommended configuration are referenced from ICAO Annex 14 Volume I “Aerodrome Design and Operations”, 8th Edition, July 2018.
FAA AC150/5345-43 regulates requirements of obstruction lights used in US and areas following FAA standards. The latest version AC150/5345-43J, addressed detailed specifications of NVG compatible with IR LEDs for obstruction lights. FAA 70/7460-1L provides a clear guideline regarding obstruction lighting configuration and installation for telecommunication towers, chimneys, buildings, catenary structures etc.
Part 139 (Aerodromes) Manual of Standards 2019, Australia CASA (2020) regulates obstruction lighting’s types, applied locations, characteristics and serviceability. It provides a rigorous guideline for owners/builders of tall structures, in terms of selecting and deploying low-intensity / medium-intensity / high-intensity obstruction lights for towers, cranes, buildings, wind turbines, chimneys, etc.
