Israel Aircraft Industries Develops Unique Helicopter Collision Avoidance System for Use During Tactical and Formation Flights
Jul 21, 2004
Israel Aircraft Industries' (IAI) Lahav Division has developed a unique mid-air collision avoidance system for helicopters. The Tactical Mid-Air Collision Avoidance (TMACA) system is a proven solution to prevent collisions during helicopter tactical mission and formation flights. Helicopters equipped with TMACA are netted to each other in a "system envelope" arrangement. The system can be used for both military and civilian helicopter fleets.
The system envelope monitors all helicopters on the network for unexpected traffic with an 15 second or less impact flight path, a 40-meter or less gap betweenhelicopters or a hover-landing collision situation. The network 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.
The system's components include a Global Positioning System, data link and radio altimeters to send data to a monitoring network that tracks the movement and location of all helicopters. It records flight data building a picture of "near misses" and gives investigators a means to prevent recurrences according to lessons learnt.
Lahav Division of Israel Aircraft Industries specializes in upgrading military aircraft and helicopter. Lahav, using the most advanced technologies and systems, upgrades a wide range of Eastern and Western military aircraft and helicopters. These upgrades provide unique solutions for enhanced capabilities and mission performance. Lahav has performed major aircraft upgrade programs for the United States Air Force, NATO air forces and other customers around the world.
