Designed for aftermarket installation on high-performance single- and twin-engine piston aircraft as well as turboprops and jets, the GFC 600 flight control system offers an impressive array of top-level safety and performance features. Leveraging technologies developed for our popular GFC 700 autopilot that drives our most advanced glass flight deck systems, these sophisticated features include Garmin ESP, underspeed and overspeed protection, automatic LVL mode, airspeed climb and decent (IAS) mode, flight director (FD) command cues and more.
Guidance from a compatible navigation source (such as GTN™ 750 or GTN 650) lets the GFC 600 system automatically fly a wide range of precision, nonprecision and GPS-guided approaches as well as holds, procedure turns, missed approaches and more. GFC 600 also includes built-in GPS roll steering capability, allowing smoother navigation tracking and eliminating the need for external roll steering converters. For installations including a compatible flight display (such as G600 or G500), flight director cues are displayed as command bars and 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. Better still, with support for a remotely installed Takeoff/Go-around (TOGA) button, the autopilot can be cued to automatically capture the correct pitch attitude required to fly a missed approach and then follow the missed approach procedure loaded in your compatible GPS navigator.
As a standard feature, Garmin ESP works with GFC 600 to assist you in maintaining your aircraft in a safe, flight-stable condition when the aircraft is being hand-flown. This ESP feature functions independently of the autopilot — though it uses the same control servos — to gently nudge the controls toward stable flight whenever pitch or roll deviations exceed the recommended limits or underspeed/overspeed conditions occur. In the event of pilot incapacitation, after the system detects that it has been activated for a specified period of time, the autopilot will engage with the flight director in level mode, bringing the aircraft back to level flight and helping to avoid the onset of inadvertent stall/spins, steep spirals or other loss-of-control scenarios. Additionally, ESP can be manually disabled to allow for intentional flight maneuvers.
With the autopilot engaged, GFC 600 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 600 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.
In addition to traditional autopilot capabilities such as altitude hold, vertical speed and heading modes, the GFC™ 600 also includes:
It’s truly a system you can own and fly with confidence. It’s easy to select an approved installation that meets your mission requirements and budget.
