The FAA has issued TSO authorization for FreeFlight’s Rangr FDL-978TX ADS-B universal access transmitter, the first V2-compliant TSO-C154c UAT ADS-B transmitter that meets the latest AC 20-165 standards, according to FreeFlight. The FDL-978TX is available at special introductory pricing through April 2012, and because it is a UAT system, can receive free weather and traffic information.
