Avionics and LSA

** Dynon's latest, the SkyView 3.0, features
synthetic vision — plus a G-meter, which was
an added feature based on homebuilder
requests.**

Key Takeaways:

  • Light Sport Aircraft (LSA) often feature advanced, "glass cockpit" avionics, offering modern technology compared to older aircraft, a trend spurred by the Sport Pilot/LSA rule.
  • A key distinction is that LSA's current ASTM standards permit the use of non-TSO'd (non-FAA Technical Standard Order certified) avionics for many components, which allows manufacturers to reduce costs, innovate faster, and implement new features and software updates more quickly than with TSO-certified products.
  • While manufacturers maintain the quality of non-TSO'd LSA avionics, the industry currently lacks formal design and performance standards for this equipment, leading an ASTM task group to develop new guidelines to ensure safety and credibility without over-burdening manufacturers.

(February 2012) The first time I climbed into the Remos G-3 it was for my Sport Pilot discovery flight. The “shiny” Dynon Avionics glass and Garmin GPS, navcom and radio did not go unnoticed as I scanned the panel. “Wow, this Sport Pilot stuff is cool,” I thought. Especially since prior to this flight I had been flying in an older Piper Cherokee Warrior. The stalwart trainer was outfitted with mechanical gauges and older navcom equipment.

Most of us know by now that the advent of the Sport Pilot/Light Sport Aircraft rule seven years ago spurred the production of new airplanes, S-LSA, that offered modern technology and performance. Thanks to the technology advances of the day and the fact that the ASTM standards that “govern” LSA (see last month’s column, “ASTM and LSA“) currently don’t include design and performance for certain equipment, many of the airplane manufacturers could install glass, for instance, or offer these advances as options to the standard panel, with virtually no red tape.
