Cobham’s HeliSAS Stability Augmentation system has received Technical Standing Order certification from the Federal Aviation Administration. The certification approves the manufacture of the HeliSAS system’s components.
According to a press release issued by Cobham, “HeliSAS is a two-axis attitude hold, attitude command, flight control system. The system has two basic functions, a Stability Augmentation System (SAS) to aid with aircraft stability and autopilot outer loop control modes for altitude hold, heading select and navigation sensor coupling. The SAS and Autopilot System provide a significant reduction in pilot workload, from takeoff to landing.”
Cobham is currently working to achieve HeliSAS certification for use on the Bell 206, Bell 407, Eurocopter AS350, and the U.S. Navy’s Bell-made TH-57 helicopters.
