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.
