Company Says The Upgrade Is Available Now

Dynon Avionics has announced the release of a new software version 5.1 for their EFIS (Electronic Flight Instrument System) and EMS (Engine Monitoring System) products. This software upgrade is available free for customers with compatible instruments.

Dynon focuses on the Light Sport Aviation and Experimental segments of the business. According to the company, the products are not FAA certified, but are permissible under the new US Light Sport Aircraft rule where the manufacturer has approved their use. 

With this latest software update, the ADAHRS (Air Data, Attitude, Heading Reference System) in the Dynon EFIS receives the ability to provide a reliable artificial horizon even when major systems in the aircraft have failed. Another change involves how the system gets airspeed information. In previous versions of the software, the attitude indication would become less accurate if airspeed became unavailable to the system. When a the EFIS is upgraded to version 5.1 and can talk to a GPS, the GPS ground speed can be automatically substituted for airspeed when the EFIS detects that the airspeed indication has failed. When this happens, the EFIS tells the pilot that its attitude indication is in a "GPS Assist" mode. The display also shows GPS ground speed next to the failed airspeed indication to help the pilot maintain situational awareness. Most importantly, when in GPS Assist mode, the attitude provided by the EFIS systems continues to be accurate. The company's' recently released autopilot also gets an IFR upgrade with the new software, including true preselects, VOR/Localizer Autopilot Tracking, and GPS steering.

The software upgrade is available for aircraft equipped with EFIS-D10A, EFIS-D100, FlightDEK-D180, EMS-D10, and EMS-D120 systems, and will be loaded with all new avionics packages.
