GMC 305 is a dedicated interface unit that allows for control of advanced autopilot modes such as indicated airspeed hold, independent flight director, VNAV steering and third-axis yaw damper (when installed with appropriate servos). While these features are available without a separate controller on G3X Touch flight displays, installing the optional GMC 305 allows for stand-alone operation of the autopilot.

Plus, the control wheel integrated into GMC 305 makes for easier pitch, vertical speed and airspeed adjustments. And for added safety, the panel’s advanced LVL mode button commands the autopilot to help restore your aircraft to straight-and-level flight.

  • To Suit Garmin GFC 500 Digital Autopilot when installed in an Experimental aircraft.
  • Requires G5, or G3x Touch system as well as GSA 28 Servos to complete a full system
  • Refer to Garmin Installation documentation for information.
  • It is highly recommended you consult with an Authorised Garmin Dealer before installing a GFC 500 Autopilot system.
  • GMC 305 Controller only (No YAW Damper this version)

Connector kit 010-12034-00 can be supplied separately.
