Bristow Installs More Tcas II

Bristow is retrofitting a fleet of 44 Sikorsky S-76C++s and Sikorsky S-92As with Rockwell Collins’s traffic alert and collision avoidance (Tcas II) system. Installations are in progress. A new-generation system, the TTR-4100, will be fitted to 20 of the helicopters. It adds traffic computer capability and enables automatic dependent surveillance-broadcast (ADS-B) in.
