Garmin GMC 307 - Part Number: 011-03993-00 (Yaw Damper), Unit Condition: Serviceable

High-end Capability for Your G3X

• Dedicated interface unit that provides advanced autopilot modes
• Control wheel for altitude selection
• Dedicated heading altitude knobs
• LVL mode button commands automatic recovery from steep or unusual attitudes
• Allows for standalone operation of the autopilot in the unlikely event of the loss of a G3X Touch display

Adding the GMC 307 control panel to your G3X autopilot gives you features normally reserved for high-end aircraft that use the GFC 700 digital autopilot system. The GMC 307 control panel is a dedicated interface unit that provides advanced autopilot modes, like indicated airspeed hold, independent flight director, and third axis yaw damper (when installed with appropriate servos). The control wheel integrated into the GMC 307 makes for easier pitch, vertical speed and airspeed adjustments, while separate knobs control heading and altitude.

Plus, for added safety, the panel’s advanced LVL mode button commands automatic recovery from steep or unusual attitudes, enabling the autopilot to return your aircraft to straight-and-level flight. And because Garmin autopilot servos interface directly with the ADAHRS, the GMC 307 control panel allows for standalone operation of the autopilot in the unlikely event of a display loss.
