The FAA's approval of Dynon's integrated touch-screen system, the SkyView HDX, for the AML that starts with the Cessna 172
takes the next step for STC avionics installations.
of the Dynon EFIS-D10A. "Historically, the attitude
indicator is not all that reliable," Stone said. Elmer Sperry
invented this gyroscopic instrument that made Jimmy
Doolittle's historic 1929 blind flight possible. "They fail,
often insidiously, where they slowly start to roll over,
and owners must have those goofy things overhauled. It's
served its purpose, but there are superior, more-reliable
technologies out there."
The most-important aspect of STC installations was
"finding alternative methods of approved equipment other
than the rigorous TSO process," Stone said. "To keep costs
affordable for $30,000 legacy aircraft, an alternate method
of approval is really the silver bullet."
In making safety-enhancing technology for legacy Part
23 aircraft more affordable, it opened an expansive new
market. The Aircraft Owners and Pilots Association gave
a suggestion of its scope in a January 2018 online poll that
asked eBrief readers: Do you fly with glass cockpits or
steam gauges? In round numbers, half the respondents flew
steam gauges, one-fifth flew glass, and one-third flew both.
Whether the respondents owned or rented doesn't
matter. Extrapolating these results, this suggests that the
customer pool for the STC installation of avionics is half
the GA fleet. In 2016, the FAA counted 211,793 active U.S.
aircraft. More than two-thirds of them had piston engines,
with 91 percent of that number having a single engine. The
FAA reported the average age as 45.7 years for singles and
43.2 years for twins.
Equally important, three-quarters of all piston aircraft
flew for personal or recreational purposes. That's 99,178
single-engine and 7,058 multiengine aircraft. To round
out this customer pool, it would be safe to assume that the
12,593 piston aircraft used for "instructional" purposes are
also potential retrofit customers who want and need new
technology, and the STC options are within their budgetary
reach.
Surely, this is contributing to the surge reported by the
2017 AEA Avionics Market Report, which documented
more than a 20 percent increase in retrofit sales over the
previous year. "Many avionics shops are telling us that
aircraft owners are electing to order full-panel avionics
upgrades rather than just the ADS-B equipment," said
AEA president Paula Derks. "It will be interesting to see
whether the retrofit market continues to grow significantly
in the next two years."
Without giving any details, market demand for the
Garmin G5 has "been sporty," Stone said. "We started with
the G5 as an attitude indicator and followed that with a
