Helicopter over city

Give your commercial helicopter pilots better traffic-threat awareness for safer operations with the TTR-4100. It's the first TCAS II system certified by the European Aviation Safety Agency and the Federal Aviation Administration for use in commercial helicopter operations.

More than 30 years of traffic surveillance product experience goes into every TTR-4100. The system enhances crew awareness of traffic threats by detecting, displaying and automatically computing avoidance maneuvers. These are aurally and visually presented to pilots for ease of execution.
