Garmin has received Federal Aviation Administration (FAA) Supplemental Type Certification (STC) for the GFC 600 autopilot in the Cessna 208/208B (with and without floats). Intended for high performance piston single/twin-engine and turbine aircraft that have a wide range of speed and performance characteristics, the GFC 600 delivers superior in-flight characteristics, self-monitoring capabilities and minimal maintenance needs when compared to older generation autopilot systems.    

The GFC 600 is designed as a standalone autopilot that boasts superior integration potential with G500 TXi/G600 TXi and G500/G600 glass flight displays, Garmin navigators, as well as a variety of third-party flight displays, instruments and navigation sources. The self-contained autopilot controller incorporates backlit keys and a bright, sunlight readable display that depicts autopilot status and mode selection. An intuitive built-in control wheel also provides convenient adjustment of aircraft pitch, airspeed and vertical speed modes. When the level button is selected, the aircraft automatically returns to straight-and-level flight. Environmentally hardened autopilot servos designed for harsh operating conditions contain brushless DC motors and a gear train that eliminates the need for a mechanical slip clutch, offering improved performance and reducing maintenance requirements when compared to decades-old servo designs on the market today. Standard mark-width design of the GFC 600 ensures the autopilot controller allows for routine installation into the aircraft’s avionics stack. Autopilot mode annunciation is available on the G500 TXi, G600 TXi touchscreen glass flight displays, as well as the G500 and G600. The addition of an optional autopilot annunciator panel also displays the selected autopilot mode in the pilot’s primary field of view and retains an identical footprint of third-party autopilot annunciators on the market.

In addition to traditional autopilot capabilities such as altitude hold, vertical speed and heading modes, the GFC 600 also includes:



As a standard feature, pilots receive Garmin ESP with the GFC 600 autopilot, which works to assist the pilot in maintaining the aircraft in a stable flight condition. ESP functions independently of the autopilot and works in the background to help pilots avoid inadvertent flight attitudes or bank angles and provide airspeed protection while the pilot is hand-flying the aircraft.

The GFC 600 autopilot for the Cessna 208/208B is available immediately for a suggested retail price starting at $31,995.
