Dynon Announces First Twin-Engine Aircraft Approval for SkyView HDX - Including Autopilot - for Piper Seneca

Dynon’s certified SkyView HDX system is now FAA-approved for installation into most Piper PA-34 “Seneca” aircraft, bringing affordable, safety-enhancing integrated avionics systems to a new category of aircraft. This is Dynon’s first approval for a twin-engine aircraft, and includes SkyView HDXs full range of capabilities, including twin-engine monitoring and two-axis autopilot.

The Seneca approval covers Dynon’s full suite of avionics, including its two-axis autopilot with coupled approach capability. Pilots benefit from an uncluttered, elegant panel layout that reduces workload, is fun to fly behind, and enhances safety. A Dynon certified installation is typically 50 to 80 pounds lighter than the instruments it replaces, and usually allows the removal of unreliable legacy equipment like the vacuum pump. 

Michael Schofield, Dynon’s Director of Marketing, says “We’re thrilled to expand Dynon’s reach to twin-engine type certificated aircraft, starting with the Piper Seneca. With this approval, SkyView HDX is in a class by itself for affordable and capable twin-aircraft avionics upgrades. With SkyView HDX, Seneca owners can also add Dynon’s full-featured Autopilot for up to half the cost of other autopilots.”

The SkyView HDX core system provides complete primary flight instrumentation, including synthetic vision, and Navigation and Mapping with Flight Planning. New to the Seneca approval is a complete twin-engine monitoring solution, covering all CHTs, EGTs, fuel flow, fuel computer, and lean assist. Also approved is Dynon’s fully-integrated two-axis autopilot, which features IFR approach capability when SkyView is integrated with a compatible navigator. The approved installation also includes options for Mode S Transponder with 2020-compliant ADS-B Out, COM Radio, ADS-B Traffic and Weather display, and Electronic Flight Bag features. A complete set of standby flight instruments are provided by a Dynon EFIS-D10A. 

Approved Model List

The SkyView HDX Approved Model List (AML) now covers all Piper Aircraft PA-34-200 Seneca, PA-34-200T Seneca II, PA-34-220T Seneca III, PA-34-220T Seneca IV, and PA-34-220T Seneca V models. Autopilot is available for Seneca II / III / IV / V models.

In addition to the Seneca, SkyView HDX is currently approved for installation into nearly 600 piston single aircraft models, with autopilots available for many C172 and Bonanza model aircraft. Dynon expects further approvals for both single and twin-engine aircraft in the coming months. In-progress aircraft/autopilot approvals include additional Bonanza models, C182, Beechcraft Baron, and the Mooney M20. See for the estimated timeline for future approvals.

Pricing and Availability

SkyView HDX for the Seneca starts at $14,189 for the core system that includes a 10” display that provides primary flight instrumentation, synthetic vision, mapping and flight planning, and a standby EFIS-D10A flight display. Twin engine monitoring with a dedicated display adds only $7,377, and includes all engine probes such as CHTs, EGTs, fuel flow, and more. The integrated autopilot is available for half the price of competing products, with configurations starting at $8580 for a fully-featured, two-axis system.

Dynon Certified products are available through a nationwide network of Dynon Authorized Installation Centers. Pilots can also opt to buy directly from Dynon and install it at their preferred avionics shop or by an A&P/IA.
