Since it was founded in 2000 and introduced its first product in 2003, Dynon Avionics has taken the lead in converting LSAs and experimental aircraft from antique "steam gages" to glass panels. Their EFIS units currently grace the panels of over 10,000 homebuilts and LSA's, where they are suppliers to the most popular LSA models.

Several factors have contributed to the expanding success of Dynon: reliability, low cost, and frequent upgrades. Starting at just $1,600 for the basic D6/D10/D100 units, or $3,900 for the newer SkyView system, Dynon comes in just slightly above the cost of the steam gages it replaces. Dynon's EFIS runs less than a third of any of the comparable certified products. It is clearly the most practical method today for creating a modern instrument panel.

The upgrades are what set Dynon apart from certified products. They are coming fast and furious, expanding the scope and usability of the EFIS units. By avoiding the laborious TSO certification process, the company is free to pursue a wide range of upgrades and introduce them quickly. The original D10A, which was designed to fit into any round 3-1/8" panel opening, has gone through many major software upgrades since its introduction. These free upgrades have included HSI capability, enhanced display graphics, networking and other devices, along with an advanced two-axis autopilot. Anyone with a current EFIS model can download every updated software product from Dynon's website, and upgrades become standard on all new units that are shipped from the Woodinville, Washington factory.

Though uncertified, Dynon EFIS does comply with the ASTM standards for Light Sport aircraft and goes through extensive testing to assure accuracy and reliability. They have a longer life and greater functionality than vacuum driven steam gages, and also significantly reduce the weight and amount of panel space required by the units they replace. Panel space is often at a premium on homebuilt and Light Sport aircraft, and saving weight is always a major advantage.

Most Dynon EFIS products can be used to control a Dynon Autopilot. Easy-to-use and highly functional controls, whether built in or on optional interface panels, are always a design feature of Dynon products. With additional new products currently in the R&D department, it will soon be possible to construct a panel that is made up exclusively of Dynon products.
