Dynon Avionics is an American aircraft avionics manufacturer that specializes in non-certified electronic avionics. Most of Dynon's instruments are not certified under FAA TSO specifications, and are developed for Experimental aircraft, Homebuilt aircraft, and Light Sport aircraft that include the avionics as part of their approved equipment during LSA certification. In the United States, aircraft of these types must operate under a Special Airworthiness Certificate.
