Automatically Return to Neutral Attitude with HeliSAS



Cobham’s HeliSAS delivers the advantages of vintage, analog autopilot and stability augmentation systems at a fraction of the cost and weight.

  • Reduced weight (under 16 lbs.). Parallel design means fewer components and maximized useful aircraft load.
  • Improved control. Stability augmentation enhances safety and reduces pilot workload.
  • Increased reliability. All-digital, full-authority system is based on dual-processor, fail-passive architecture.
  • Affordability. Cost-efficient safety and control system for Part 27 helicopters.



HeliSAS Reduces Pilot Workload.
As a two-axis attitude hold, attitude command, flight control system, HeliSAS significantly reduces pilot workload. When engaged, the pilot may perform cockpit functions hands-free.


HeliSAS Enhances Flight Stability.
As one of HeliSAS’ two main functions, the Stability Augmentation System (SAS) provides precise control during all modes of flight, regardless of wind conditions or aircraft center of gravity.
