Researchers at the MIT International Center for Air Transportation are working to identify potential ADS-B (Automatic Dependent Surveillance - Broadcast) applications that would be useful for flight operations, and they are seeking input from pilots. "We are very interested in getting representation from all aviation segments that could potentially benefit from ADS-B, including Helicopter, Fixed Wing, Part 135 operations, Part 121 operations and the military," Prof. R. John Hansman tells AVweb . Pilots are invited to complete an online survey, which requires no prior knowledge about ADS-B and takes less than 10 minutes to complete, Hansman said. This survey will be useful in informing the FAA on ADS-B implementation, but it is only advisory and other factors may influence the final ADS-B implementation plans, he added. ADS-B is an alternative to radar, where aircraft broadcast their altitude, heading, GPS position and other information to ground stations and other aircraft. The ADS-B datalink used to transmit and receive these aircraft positions can also be used to uplink weather and traffic information to the cockpit.
