New York (AirGuideBusiness - Business & Industry Features) Tue, Nov 3, 2015 - Modern aircraft have the technology to avoid crashing into one another in the sky, but what happens when they're back on the ground? Traffic collision avoidance systems (TCAS) were developed to handle the majority of aircraft collisions, which generally happen during the cruise phase of flight. These systems operate by using transponders to ping other aircraft repeatedly and create a trackable trend of the aircraft's flight. However, these systems can result in cluttered data when transponders are concentrated on the ground in airports. This can leave aircraft on the runway open to a collision. Improving Collision Avoidance The recently patented Aerial, Landing and Takeoff Aircraft Crash Avoidance System (ALTACAS) offers an update to current TCAS systems. It is designed to detect and monitor other aircraft, drones and vehicles at or near ground level in airports. What makes this system different is that unlike the existing TCAS system, ALTACAS does not use transponders. Check out how the ALTACAS system works: The video highlights the combination of light detection and ranging (LIDAR) radar technology and GPS tracking used in the ALTACAS. Neither technology interferes with radio signals from air traffic controllers. Avoiding Runway Collisions By mounting multidirectional LIDAR housings on strategic areas of the plane such as the nose and wings, ALTACAS enables the plane to "see" other craft around itself. To monitor other craft, the system provides imagery and information about the oncoming vehicle's distance, speed and direction. It can also automatically open a three-way communication between both vehicles and the nearest air traffic controller when it senses an issue such as a potential collision...
