Part of the job was a custom panel, just VFR, and with traditional steam gauges. Unfortunately a little too soon for EFIS. However, as we now near completion of the next project (a Murphy Elite on amphibs, to replace the Rebel we had before the Falco), there is no choice but EFIS. We have chosen Grand Rapids dual EFIS display system with a single AHRS and single magnetometer. The machine is essentially VFR, but I can see days, like Al, where I might get caught and want the safety of this system. It's also a lot lighter, reasonably redundant with two displays (it could be more so with dual AHRS), and eliminates vacuum needs. In choosing GRT, I considered many factors. I came to the conclusion that every system has its pros and cons, and for us, the GRT was the best "compromise". Considerations were price (couldn't afford to even look at Chelton) and size of display. Also, it links seamlessly with the Tru-Trak autopilot and all the Garmin/UPS radios, including the 430/530, SL30/40 nav/comms, and their GTX transponders. The EFIS takes advantage of much information from these systems, and also outputs to many of them. For our needs (and an extra $350 as I recall), we also got one of the systems with a built in Garmin GPS engine. I also liked the designer's background (727 display systems) and his approach to redundancy and fault tolerance. Another consideration is that any one of these shops could go belly up tomorrow. I can't control that, but I did consider that my risk was limited by the fact that GRT is also home to the long standing EIS LCD-panel engine monitoring system, and the EFIS designer is also company owner of the Princeton capacitance fuel gauges. I'm wiring now. I'm sure I'll come back here and gush ecstatically when all that glass lights up for the first time. Only one fault I can see with an "all electric" float plane. If I ever flip it over, not only do I have to worry about safe egress upside down in the water, I might also electrocute myself...

Just for clarification.the GRT's will go into the Elite? Not the Falco? Are you still considering an upgrade of the Falco panel?
