All it takes is the addition of Garmin’s affordable GSA 28 “smart” servo units to give your G3X a range of autopilot capabilities similar to those provided by the high-end GFC™700 systems found on thousands of certified aircraft. You have the option of purchasing 1 servo (roll only), or 2 servos (pitch + roll) to add the level of capability you want. Even better, the Garmin system includes automatic trim functionality at no additional cost. And for added redundancy, it’s the only integrated autopilot in its class to offer standalone operation in the event of EFIS display outage or shutdown.
The optional GMC 305 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). A control wheel integrated into the GMC 305 makes for easier pitch, vertical speed, and airspeed adjustments. 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. Installation of the system is simple and straightforward, with industry-standard servo mounting kits available — as well as airframe-specific versions for the popular Van’s RV series (RV-4/6/7/8/9/10 models).
