Rockwell Collins initiates project to validate ADS-B requirements in Europe

Rockwell Collins, in collaboration with multiple helicopter operators*, the European Aviation Safety Agency (EASA), Eurocontrol, and the Netherlands Civil Aviation Administration, recently completed an operational evaluation to successfully validate automatic dependent surveillance broadcast (ADS-B) out airworthiness requirements for helicopters operating over the North Sea. The multi-year project, of which Rockwell Collins was a leading participant, consisted of flight tests using Rockwell Collins TDR-94D transponder and, in some instances, Rockwell CollinsGPS-4000S GPS Sensor.

Based on the project’s results, Rockwell Collins and its collaborators proposed new ADS-B equipment configurations for helicopters to EASA and approval is expected later this year.

“The complexities of helicopter airframes require a different set of design and implementation criteria than fixed-wing aircraft,” said Claude Alber, vice president and managing director of Europe, the Middle East and Africa (EuMEA) for Rockwell Collins. “Knowing that GPS interference issues can arise due to the differences in aircraft attitudes during operations, helicopter airframes, engines and rotor blades, creates the need to evaluate each platform independently in order to meet the ADS-B out operating requirements.”

The integration of ADS-B out capability on helicopters greatly enhances the surveillance capability of air traffic control, especially during flights to offshore oil platforms over the often-stormy North Sea where radar surveillance is not available beyond line of sight.

In addition to its role in providing ADS-B out capability for helicopters, Rockwell Collins TDR-94D transponder is a certified Mode S transponder that complies with European surveillance requirements and is installed in thousands of business, regional and helicopter aircraft.

Rockwell Collins GPS-4000S Sensor provides enhanced GPS capability for ADS-B out implementation on helicopters. The unit is the essential system for providing high integrity position, velocity and time information for aircraft navigation, ADS-B out, and LPV (localizer performance with vertical guidance) operations.
