Straub of Garmin says the upward trend in sales of the company’s glass cockpit avionics, including the fi rm’s GFC 500 autopilot, indicates that some pilots are choosing to fl y light aircraft over longer distances. Saying a Cessna 172 has an autopilot feels like an oxymoron but, it’s not too far away from being our No. 1-selling GFC autopilot sales platform, Straub notes.
