![]() The visual approach slope indication system can help the pilot to keep the aircraft sliding correctly on the flight path during the approach phase. ![]() The high intensity precision approach lighting system can be divided into Ⅰ, Ⅱ and Ⅲ categories. According to the visibility standard of the runway ready to accept aircraft, different types of approach lighting systems are installed, such as low light intensity simple approach lighting system, medium light intensity approach lighting system for non-instrument runway and instrument approach runway high light intensity precision approach lighting system for precision approach runway. International Civil Aviation Organization on the optical performance of various types of lamps and lanterns are clearly defined.ġ, Approach lighting system: guide the approach of the aircraft to the runway centerline, wing level and estimated approach distance to the runway entrance. In the absence of backup power supply airports should be equipped with emergency lights. Small airports can also use mobile, semi-fixed lights. General airports are installed fixed lights. The luminous intensity of the light is divided into low light intensity, medium light intensity and high light intensity. The graphics, color, light intensity and coverage of the aviation lighting system should not only be suitable for the operation of the airport, but also in line with the country's development or international common technical standards. ![]() By the approach lighting system, visual approach slope indication system, runway lighting system, taxiway lighting system and other lighting systems. An engineering facility that provides visual guidance signals to pilots during aircraft night flight and low runway visibility.
