Flying the Falco just coming up to four years. 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...

Hi Mike,
Good on you! Just for clarification.the GRT's will go into the Elite?
Not the Falco? Are you still considering an upgrade of the Falco panel?
