Abstract
The calculations results of LED light intensity necessary for reliable visual detection of runway lights in field conditions are presented. The following groups of LED lights are considered: approach threshold lights, lights of the last 600 m of a runway, and runway end lights. Detection threshold were chosen. The effectiveness of LED lights is analyzed in different weather conditions during the night, at twilight, and in the day time, and questions of speed adjustment of LED radiation intensities in accordance with ICAO standards are considered.
