Technology helps prevent mid-air mishaps.Mid-air helicopter crashes may become a thing of the past. The Lahav division of Israel Aircraft Industries has developed a system that predicts collisions during tactical missions and formation flights. Called the tactical mid-air collision A mid-air collision (MAC) is an aviation accident where two or more aircraft come into unplanned contact during flight. Due to the high velocities involved in modern aviation, this usually results in very severe damage (if not total destruction) of all aircraft involved. avoidance system, it alerts pilots on the network of unexpected traffic with a 15-second or less impact path. a 40-meter or less gap between helicopters, or a hover-landing situation. The network said a company official, "calculates collision conditions using a dynamic, high-trajectory evaluation algorithm and automatically alerts the pilot with recommended avoidance measures if a potential collision is predicted." Among its key components are a global positioning system Global Positioning System: see navigation satellite. Global Positioning System (GPS) Precise satellite-based navigation and location system originally developed for U.S. military use. . data link, and radio altimeters radio altimeter: see altimeter. that keep track of helicopters in the network. Officials said the collision avoidance system (1) See adaptive cruise control. (2) A passenger car system that detects objects on the road that the driver may not be able to see. Using radar or infrared sensors, distant objects, such as a deer crossing the road at night or in a fog, are projected onto the possesses applications for both military and commercial aircraft. |
