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 modern, "glass cockpit" avionics that typically do not require the rigorous FAA Technical Standard Order (TSO) certification mandated for standard-category aircraft.
  • The absence of TSO requirements, under current ASTM standards for LSA, allows manufacturers to produce more affordable avionics and innovate rapidly, incorporating new features and software updates much quicker than with FAA-certified equipment.
  • While manufacturers contend that the quality of non-TSO'd LSA avionics is comparable, an ASTM task group is actively working to develop specific design and performance standards for LSA flight instruments and avionics to address the current lack of official criteria.

(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.
