Optical design of airport temporary runway closure warning light

Due to lack of navigation facilities of current airport runway closure and relevant standards disunified, it is difficult to pilots in harsh visual conditions and safe distance to provide eye-catching and effective runway closed information, which causes hidden dangers to airport safe operation. Aiming at this problem, this paper establishes a temporary airport runway shutdown warning light model based on human visual characteristics, designs and analyzes light intensity of warning light lamp by point by point method. Then warning process is simulated. Simulation results show that X-shaped warning light can be recognized at 2 km, and runway closed information can be distinguished by pilots clearly, accurately and rapidly. This plays a warning role for pilot and also provides theory basis for development of warning light.
