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 utilize non-TSO'd (Technical Standard Order) avionics, differing from the rigorously FAA-certified equipment required for standard-category aircraft.
  • This non-TSO approach, operating under ASTM standards, allows manufacturers to innovate more quickly, introduce new features, and offer products at a significantly lower cost compared to TSO'd equipment.
  • Manufacturers like Dynon and Garmin benefit from reduced development time and expense, enabling faster software updates and product iterations by avoiding lengthy FAA certification processes.
  • Although manufacturers assert comparable quality, the current absence of specific performance standards for LSA avionics means their official effectiveness lacks formal proof, a gap an ASTM task group is actively working to address.

(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.
