Safety First. Safe, accurate mission completion and pilot productivity are paramount among helicopter owners and pilots, and at Chelton Flight Systems. Everything we do revolves around the need to get the assigned mission – human transport, cargo hauling, medical evacuation, law enforcement, firefighting – completed with all passengers and crew returned safely to their destination.

New: HeliSAS

Chelton’s continuing quest to improve helicopter safety and productivity has resulted in the development of HeliSAS, the first affordable, lightweight stability augmentation and autopilot for medium and light helicopters.


HeliSAS will enable hands-free flight while maintaining heading or navigation course and attitude – even during turbulent conditions – resulting in increased safety and workload reduction.

HeliSAS is:

  • Lightweight: Only 12.7 lbs. installed – including panel-mounted gyro.

  • Expandable: Stability Augmentation System (SAS) only...or SAS + full autopilot.

  • Easy to install: 40 hours or less installation time.

An optional autopilot system further enhances HeliSAS’ capabilities. Functionality includes: Altitude, heading hold, track GPS course, track VOR, track ILS, backcourse localizer, VNAV approach with WAAS-capable GPS, and VNAV enroute with Chelton EFIS.

HeliSAS will be STC’d for the Robinson R44 in early 2008, with the Bell 206/407 to follow thereafter.

Flightlogic Efis

Operators of medium and light helicopters have made Chelton Flight Systems’ FlightLogic the #1 selling 3D Synthetic Vision EFIS. With it, pilots can improve operational capability, reduce accidents, enhance productivity, as well as safely and confidently fly the most challenging missions.

The FlightLogic EFIS integrates breakthroughs like 3D Synthetic Vision, graphical Flight Management System (FMS), Highway-In-The-Sky (HITS) navigation, Hover Vector, Head-Up Display (HUD) symbology, Unusual Attitude Recovery (UAR), helicopter TAWS, and much more in a single, intuitive display.

3D Synthetic Vision

Chelton’s EFIS is the only FAA-certified avionics system to display three-dimensional terrain, obstacles, and traffic in real time on the Primary Flight Display (PFD).

Highway-in-the-Sky (Hits)

HITS allows flight with ILS precision to any point in the world. The route appears on the PFD as a series of green boxes superimposed over the flowing terrain of the 3D Synthetic Vision. Simply fly through the boxes to follow the route.

Helicopter Taws

HTAWS gives critical visual and audio cues when terrain or obstacles present a hazard. Class A or B HTAWS in the Chelton EFIS increases situational awareness and safety by monitoring multiple situations – terrain or obstructions one minute ahead, hazardous AGL conditions, high descent rate at low altitude, and sink rate detection after takeoff or during a missed approach.

Hover Vector

Hover Vector enhances productivity, providing precise feedback during surveillance, long-line work, and other precision procedures. When airspeed drops below 30 knots, the Flight Path Marker on the Primary Flight Display converts to a "bulls-eye" ringed by concentric circles that delineate 15- and 30-knot ground speeds.

Unlike conventional flight instruments, FlightLogic provides real time 3D navigation, terrain, towers, traffic, HTAWS, HITS, and FMS in a single, integrated system. The result is tremendously enhanced awareness, unprecedented safety, greater productivity, and a dramatically reduced pilot workload.

Chelton’s Synthetic Vision EFIS is STC’d for Bell 204/205/206/210/407, Eurocopter AS 350/355 and the EC 120 B.
