OLATHE, Kan./Jan. 21, 2020/ – Garmin® International Inc., a unit of Garmin Ltd., today announced it has received Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) approval for the 
GFC 600 digital autopilot in select Beechcraft King Air C90 aircraft and E90 aircraft1. The GFC 600 digital autopilot is optimized for turbine aircraft, delivering superior in-flight characteristics and new operational capabilities such as Vertical Navigation (VNAV), automatic Course Deviation Indicator (CDI) switching when paired with a GTN Series navigator, enhanced go-around capability and much more.

The GFC 600 certification for the Beechcraft King Air C90 and E90 provides owners and operators an autopilot upgrade that boasts superior integration potential with G600 and G600 TXi flight displays, the 
GI 275 electronic flight instrument, as well as the GTN and GTN Xi Series of navigators. 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 offering improved performance and reducing maintenance requirements when compared to decades-old servo designs on the market today. In addition, these servos are optimized for turbine aircraft by offering more torque to help better command and respond to control demands required of turbine aircraft.

Standard mark-width (6.25-inch) design of the GFC 600 mode controller ensures the autopilot controller allows for routine installation into the aircraft’s avionics stack. Autopilot mode annunciation is available on the G600 TXi touchscreen glass flight display, as well as the G600 flight display. 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.
