Garmin has received FAA supplemental type certificate (STC) approval for its GFC 600 digital autopilot in Beechcraft King Air F90s. The GFC 600 reduces workload and brings additional functions such as vertical navigation (VNAV), automatic course deviation indicator (CDI) switching when paired with a GTN series navigator, and enhanced go-around capabilities, including missed approach sequencing. Installations in King Air F90s will be available at select Garmin-authorized dealers starting next week.

The autopilot upgrade allows integration with G600 and G600 TXi flight displays, the GI 275 electronic flight instrument, and the GTN and GTN Xi series of navigators. The self-contained autopilot controller incorporates backlit keys and a sunlight-readable display that depicts autopilot status and mode selection.
