GFC™ 500 Digital Autopilot

Smart Technology, Easily Accessible
Drawing on top-end Garmin flight control technology from our GFC 700, GFC 500 provides crisp, precise response and optimum performance over the entire airspeed envelope of your aircrcaft. Rather than depending on failure-prone mechanical gyros, the GFC 500 system is digitally controlled, using solid-state attitude and air data sensor reference — giving you ultra-smooth roundouts, intercepts and more while also enhancing the reliability of the system. Incorporating the highly adaptable GI 2751 electronic flight instrument, or our crisp, easy-to-read 3.5” G5 electronic flight instrument¹, a mode controller and “smart” servos, the autopilot’s architecture supports full pitch-and-roll axis control capabilities with optional pitch trim for automatic and manual electric trim. Additionally, yaw damper capability is optionally available for select aircraft models.

With the optional GAD™ 29 nav data adapter (not required with GI 275), GFC 500 will interface with modern Garmin navigators such as the GTN™ Xi series and legacy GNS (WAAS and non-WAAS) series navigators to fly a wide range of precision, non-precision and GPS-guided approaches as well as holds, procedure turns, missed approaches and more. GFC 500 also includes built-in GPS roll steering capability, which allows smoother navigation tracking and eliminates the need for external roll steering converters. Flight director cues are displayed as command bars on the GI 275 and G5 electronic flight instrument, as well as optionally on a G3X Touch, G500 or G500 TXi flight display². The command bars are always in view when the autopilot is doing the flying — and may also be used for visual guidance when you’re hand-flying the aircraft. With support for a remotely installed Takeoff/Go-around (TOGA) button, the flight director can be cued to automatically indicate and capture the correct pitch attitude required to fly a missed approach and then follow the missed approach procedure loaded in your compatible GPS navigator. Up to two GI 275 or two G5 electronic flight instruments1 can be interfaced with the GFC 500 autopilot in your aircraft, providing full reversionary display capability.

Mode Control at Your Fingertips
A mode controller is included with your GFC 500 package, and its compact size and mark-width design require only minimal space in your avionics stack while providing easy access to all autopilot modes and functions. You can select advanced lateral and vertical modes such as pitch hold, altitude preselect, altitude hold, vertical speed and indicated airspeed hold as well as roll, track and selected heading. An intuitive control wheel integrated into the GFC 500 mode controller allows for easy and precise pitch, vertical speed and airspeed adjustments, while separate knobs allow quick twist control of heading and altitude. For added safety, a dedicated LVL button on the controller lets you command the autopilot to automatically return your aircraft to straight-and-level flight — and thus help avert a potential loss-of-control situation.

An Autopilot Knows Its Limits
With the autopilot engaged, GFC 500 also provides overspeed and underspeed protection. In a high airspeed situation — for example, if you’re descending and your aircraft is approaching VNE or VMO — the system will increase the aircraft’s pitch attitude, preventing a further increase in airspeed and potential structural damage. Likewise, at the other end of the speed spectrum, GFC 500 provides underspeed (stall) protection. For example, in the event the pilot does not immediately advance the throttle to full power, with the autopilot engaged while flying a missed approach sequence, the autopilot will help prevent an aircraft stall by reducing pitch attitude and provide the pilot with an “airspeed, airspeed” audible alert.
