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

Key Takeaways:

  • Light Sport Aircraft (LSA) frequently feature modern "glass" avionics that are often non-TSO'd (not FAA Technical Standard Order certified), distinguishing them from the rigorously certified equipment required in standard-category aircraft.
  • Manufacturers opt for non-TSO'd avionics in LSAs primarily due to significant savings in time and cost by avoiding the lengthy FAA certification process, which also enables greater innovation and faster product development.
  • While many non-TSO'd LSA avionics are considered high-quality and proven in the field, there are currently no specific ASTM performance standards in place for them, leading to a reliance on manufacturer claims and user experience.
  • An ASTM task group is actively developing design and performance standards for LSA flight instruments and avionics, aiming to enhance safety and ensure quality without imposing the extreme costs and burdens associated with traditional FAA certification.

(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.
