Rockwell Collins Receives ADS-BApproval for TDR-94/94D Transponders
Rockwell Collins has obtained what is said to be the first FAA TSO approval for ADS-B (automatic dependent surveillance-broadcast) functionality for use with mode-S transponders. The approval will allow for enhanced traffic situational awareness on the airport surface and during flight, as well as for visual see-and-avoid maneuvering, sequencing and merging, crossing and passing operations and oceanic in-trail procedures, Collins said.
The Collins TDR-94/94D (-108 versions) is the first transponder series to comply with the international RTCA DO-260A standard, developed for surveillance applications in tomorrow’s airspace, including ATC surveillance in en route, terminal area, non-radar area and surface movement environments. The TDR 94/94D transponders are also approved by the European Aviation Safety Agency to support elementary and enhanced surveillance.
