Rockwell Collins Receives ADS-B OK For TDR-94/94D Transponder
August 8, 2005
Rockwell Collins said it received the first U.S. Federal Aviation Administration (FAA) Technical Standard Order TSO-C166 approval for Automatic Dependent Surveillance - Broadcast (ADS-B) functionality on Mode-S transponders.
The approval for its TDR-94/94D transponder, said the company, enables:
- Enhanced traffic situational awareness on the airport surface and during flight.
- Visual acquisition for see-and-avoid, sequencing and merging, crossing and passing operations.
- Oceanic in-trail procedures.
According to Rockwell Collins, its TDR-94/94D transponder is the first to be fully compliant with the international RTCA DO-260A standard, officially known as Minimum Operational Performance Standards for 1090 MHz Automatic Dependent Surveillance - Broadcast (ADS-B) and Traffic Information Services (TIS-B).
The implementation of this standard ensures the integrity and accuracy of data necessary to fully support future surveillance applications proposed for airspace modernization, including air traffic control surveillance in en-route, terminal area, non-radar area and surface movement domains, according to Rockwell Collins.
The company noted that the TDR 94/94D transponder is approved by the European Aviation Safety Agency (EASA) in accordance with ETSO-2C112A and is compliant with the latest draft ETSO-2C112B standards to support both Elementary and Enhanced Surveillance.
Elementary and Enhanced Surveillance allows the transponder to reply to ground-based Secondary Surveillance Radar interrogations supplying air traffic controllers with enhanced surveillance information. The TDR-94/94D continues to support Traffic Alert and Collision Avoidance System II (TCAS II) functions, said Rockwell Collins.
Operators with existing Pro Line radio installations can update the TDR-94/94D transponders through appropriate service bulletins.
