<p>System for approach and landing of aircraft on airfields in conditions of prohibitive visibility due to fog. It is part of the present widespread ILS (Instrumental Landing System) when, having reached the minimum level of category II (minimum category II: 100 foot level and 350 meters visibility), it is not possible to continue with the landing by visual means. The runway is made visible on board, with its lights, on a display, in two analog modes. A) particular use of infrared technology. B) detection of radio pulses. A virtual runway will appear on the video during the entire approach in category II, in the proper perspective as the aircraft gradually approaches the ground, until being superimposed on the lights when they appear, detected by the sensors of the instruments. As in a simulator, the pilot will perform the landing. <IMAGE></p> |
