Is EFIS/One certified for GPS approaches?
On the advice of our most trusted avionics dealer and partner, we have decided not to pursue it. For what it will cost to do TSO C129A testing and certification, we’d have to raise the price of the EFIS by more than the cost of a high-volume certified unit. We think it’s a better deal to have a reasonably priced glass cockpit, and the interconnect available for those who want to fly GPS approaches. If you have a certified GPS, you can plug it in to drive the flight director and autopilot in approach mode.
