Cowan's HeloSAS uses small cyclic corrections to stabilise the helicopter. The manual distinguishes force-trim behaviour with SAS engaged and disengaged, and explains the difference between spring-centred and non-centring controls. Its upper autopilot modes become selectable above 44 knots in the documented implementation. Stability assistance, rotor-speed governing and route-following modes are separate systems.

The X-Plane SAS guide distinguishes trim release, upper-mode disconnection and the underlying stability system. Its published force-trim-release and autopilot-disconnect commands have different effects: disconnecting the upper modes can preserve SAS. The documented 44-knot threshold applies to mode availability, not to a universal helicopter operating limit.

Bell reworked an unsuccessful military observation-helicopter proposal into the commercial JetRanger. The resulting 206 family became widely used for passenger transport, observation and utility work. The familiar single-engine versions use a two-bladed main rotor.
The 206B JetRanger and stretched 206L LongRanger are separate branches of that story. Their cabins, engines and equipment are not identical. Cowan documents each model's trim, autopilot and stability-assistance features separately.

Bell 222 family · CowanSim · CowanSim · MSFS 2020 · MSFS 2024
The 222 autopilot guide says pressing SBY once removes armed or active autopilot modes while leaving Auto Trim/SAS active. It documents autopilot availability above 44 knots, with SAS required for those modes. This describes CowanSim’s software system.

TacFlight 58D · TacFlight · MSFS 2020 · MSFS 2024 (legacy compatibility)
The TacFlight manual describes force-trim and SCAS switches. Its vertical situation display presents flight information; the display itself is not evidence of a hover autopilot.

Lionheart Creations Bellanca Super Viking 17-300A · Lionheart Creations · MSFS 2020 · MSFS 2024
The seller identifies Lionheart's rendition as a 17-300A with a turbocharged 300 hp engine and Century III autopilot. The aircraft has retractable landing gear, with different interior and panel presentations.
Product description, configuration and simulator editions
The Bellanca Super Viking combines a wooden wing with a steel-tube fuselage and a four-seat cabin. Retractable landing gear accompanies the touring-aircraft layout.
Lionheart's product describes its own 17-300A rendition with a turbocharged 300 hp installation and Century III autopilot. That engine description belongs to the developer's represented aircraft. Panel and interior options remain configurations within the same product.
Bellanca Super Viking
The BW 635RG combines a Rotax 915 iS installation with retractable landing gear. The Orbx model uses single-lever power control for the engine and propeller, with stick controls, elevator trim and flaps. Its GFC 500 provides the documented autopilot functions.

727 Series Professional · FlyJSim · X-Plane 11
FlyJSim distinguishes the independent FD-108 flight director from the SP-150 autopilot, including their mode interlocks. Custom control-surface behaviour accounts for hydraulic pressure, blow-down and standby operation. The FD-108 is a flight director, not another autopilot installation.
