CiES is a proud sponsor of pilot Mindy Lindheim and the Chasin' Tailwinds YouTube Channel
In this video, Mindy discusses what she loves about upgrading her 1957 Cessna 182 with new CiES fuel sensors (and a few other goodies).
"The flight from Atlanta to Florida (it was almost a three hour flight), I would have never done that without the EIS and my new CiES fuel senders. I would have had to make one or two fuel stops because I would have not been confident I had enough fuel on board."
"So this is a game changer for me. It saved me so much time coming down here to Florida, knowing how much fuel I had on board."
