The Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO) have regulations & set recommendations for the installation of aviation warning light systems on tall structures. Any structure that exceeds 200 ft about ground level is required to be properly marked with aircraft warning lights. Industrial chimneys, wind mills & turbines, smokestacks, water tanks, pylons, cranes, and broadcast masts & towers that reach above this height must be clearly visible to aircrafts at any time during the day or night.
Aircraft warning lights (AWL) are also required to have specific features in terms of beam pattern, light intensity, light color, and number of lights based on international regulations and national standards. The setup of your structure’s AWL system will vary depending on local terrain features, weather patterns, geographical locations, and the shape & layout of the structure or surrounding structures that need to be lit. Our rope access experts can help you determine the layout of an AWL system for your structure and will personally engineer a solution to get your structure up to code quickly, efficiently, and economically.
Types of Lights
According to the ICAO, the lights used in an AWL system must be distinguished by a set of parameters: beam patter, color, intensity, and flash rate. There are 3 main groups to consider as stated by the ICAO:
- Low intensity obstruction lights: these lights should be used where the object height above the surrounding ground is lower than 45 m.
- Medium intensity obstruction lights: should be used where the object height above the level of the surrounding ground is higher than 45m.
- High intensity obstruction lights: these lights should be used to indicate the presence of an object if its height above the level of the surrounding ground exceeds 150m.
Location of Lights
The number of light units recommended for your project will depend on the diameter & shape of the structure. The lights should be arranged in a manner that allows the object to be seen from every angle in azimuth, giving clear indication of the size, shape, and diameter of your structure. The FAA has set up dimensional guidelines that state that any object with a diameter of up to 6m will require 3 lights, and any object with a diameter of greater than 6m will require 4 lights.
Whether your Aviation Warning Light system needs repairs or replacement, Industrial Access can get the job done quickly, at a reasonable rate, and using methods that will ensure minimal disruption at your plant or facility.
