摘要

One of the most important problems for pilots, is landing on runways in dense foggy nights, that visibility is very poor I.e. less than 50 meters. Even with the help of navigational systems like ILS, radar, etc… from point of psychological view of the problem, it is difficult for a pilot to land when he or she can not see landing runway even the indicators show the correct course I.e. center line of runway and glide angle. On the other hand many countries like England, most of times have dense foggy weather and this problem forces an inordinate amount of expenses for airlines due to delays and landing in alternate airports, etc… On the other hand dissatisfaction and probable economical losses for passengers are some of other profiles of above mentioned problem. L3S or laser light landing system provides a very efficient, with no harm in any conditions for pilots eyes, illumination of runway, touch down point and edges of runway before decision altitude I.e. about 400 feet. For the sake of security in the following calculations the decision altitude is recognized 200 meter or about more than of 600 feet, I.e. the pilot will see the illuminations at 200 meter altitude and has enough time to decide to land or not. It should be emphasized that, there will be no direct interception of light beam of laser to the pilot's eves that the potential of any harm to the pilot's eves reduces to zero probability.
