HeliSAS - A Stability Augmentation System and Autopilot for the R44


An Attitude Stabilization System to Enhance the Safety and Utility of the Robinson R44 Helicopter

With the push of a button, the HeliSAS converts the R44 from an unstable aircraft with very light stick forces to a highly stable platform with enhanced control feel that provides force feedback to the pilot.  HeliSAS makes the R44 feel like a much larger, more stable helicopter.

 

With this sytem engaged it is possible for the pilot to remove his or her hand from the cyclic to fold charts or perform other cockpit duties.  The R44 will hold attitude indefinitely with the HeliSAS engaged.

 

The prototype HeliSAS has undergone over 140 hours of flight testing and is fully functional. 

It is virtually impossible to lose control of the R44 with the HeliSAS engaged.  That is because the aircraft will always return to a level attitude if the pilot releases the controls.  Large attitudes can only be achieved if the pilot holds a constant force on the controls of more than 5 lbs in pitch and 3 lbs in roll.
