Rockwell Collins Tests ADS-B Avionics
Rockwell Collins announced it has completed a series of FAA evaluation flights meant to test automatic dependent surveillance-broadcast (ADS-B) and cockpit display of traffic information (CDTI) avionics. The tests, designed specifically to assess the concepts during airport surface operations, were conducted at Memphis (Tenn.) International Airport as part of the FAA’s ongoing Safeflight 21 program. The goals of the program included evaluation of prototype moving maps for airport surface situational awareness, as well as definition by the FAA of avionics certification requirements. This was the third in a series of evaluations in which Rockwell Collins has played an active role, according to a spokeswoman. Collins tested its TPR-901 mode-S transponder with the ADS-B transmit, or “squitter,” function and 1090-MHz link to the onboard TCAS. ADS-B information from other aircraft, as well as information from a ground-based traffic information surveillance-broadcast (TIS-B) station, was integrated with TCAS sensor data and displayed on a five-inch MFD installed in the cockpit of an FAA test airplane. TIS-B uses multilateration sensors and surface radar to identify positions of aircraft.
