Flight-testing is well under way for a new helicopter autopilot that, compared with other currently available systems, cuts both weight and cost in half, sources familiar with the project told AIN.

The HeliSAS digital autopilot, under development by Chelton Flight Systems and Hoh Aeronautics, is a full-authority system that can be installed in any helicopter with hydraulic controls. HeliSAS supports all conventional autopilot modes, as well as Chelton’s highway-in-the-sky roll and pitch steering when coupled to Chelton’s synthetic-vision EFIS.
