Dynon Avionics best-selling EFIS-D10A is now STC approved for installation in type certificated aircraft.
- The EFIS-D10A is an STC’d replacement for the failure prone attitude indicator in type certificated GA aircraft.
- Initial STC covers Cessna 150, 152, 172 and Piper PA-28 and PA-38 models. More aircraft approvals expected.
- Proven in thousands of Experimental and LSA aircraft over 10+ years.
- Details about pricing and availability to follow.
The Dynon EFIS-D10A is the first product to be STC approved. The EFIS-D10A is a full 4” Primary Flight Display that includes attitude, airspeed, altimeter, magnetic heading, turn rate, inclinometer, g-meter, winds, and more. Other capabilities include Angle-of-Attack and internal backup battery. The initial STC allows the EFIS-D10A to replace the existing primary attitude indicator in Cessna 150, 152, 172 and Piper PA-28 and PA-38 series aircraft with a modern EFIS that contains no moving parts. More aircraft approvals are expected to follow. Based on demand, Dynon also will design turnkey installation kits for installers that include aircraft-specific panels and mounting equipment. The STC will be available for a nominal price from the EAA. Dynon will sell the EFIS D10A and installation kits for STC installation through selected dealers. Unique to this STC, EAA, Dynon, and the FAA worked together to allow the EFIS-D10A to be installed without the traditional Technical Standard Order (TSO) or Parts Manufacturer Approval (PMA) requirement. Dynon’s product is also verified against the recently developed ASTM 3153-15, Standard Specification for verification of Avionics Systems. The EFIS-D10A was flight tested in Oshkosh earlier this year in an EAA Cessna 172M. The cost and application process for the STC will be finalized in the coming weeks by EAA. Pricing and availability of Dynon’s EFIS-D10A for this STC will also be available in the coming weeks. Visit the EFIS-D10A STC web page for more information. Download the EFIS-D10A brochure.

Frequently Asked Questions How am I able to put a Dynon EFIS-D10A in my type certificated aircraft? The EAA, FAA, and Dynon combined their expertise to enable the installation of commercially available avionics systems into certain type certificated GA aircraft. Based on the success of our proven product development process in the experimental market, the FAA is authorizing STC installation of the EFIS-D10A as a replacement for the primary attitude indicator in small GA aircraft. The EAA — with Dynon’s help — developed the STC. Customers will buy a Dynon EFIS-D10A from their Dynon dealer/installer and the STC from EAA. Like any STC, installations must be signed off by an A&P. Who is Dynon Avionics? Dynon Avionics is the leading producer of avionics for Experimental and Light Sport Aircraft, with over 15,000 aircraft equipped all over the world. The EAA chose Dynon for this STC because of its proven success in the market. Dynon’s product line spans from the D2 portable attitude indicator to its fully-integrated SkyView system. The EFIS-D10A was one of the first products Dynon released, with thousands installed and flown since 2004. Why do I buy the STC from EAA and not Dynon? The EAA’s close working relationship with the FAA was key to this program’s success. The EAA, with Dynon’s help, developed this novel STC approach. Dynon is the launch partner for this STC process. What aircraft are approved under this STC? The initial STC obtained by the EAA covers Cessna 150, 152, 172 and Piper PA-28 and PA-38 models. Additional aircraft approvals are expected to follow. Is the EFIS-D10A TSO’d? Does Dynon have PMA? No. This STC demonstrates that Dynon commercial products are suitable for use in type certificated aircraft. Neither TSO nor PMA are required to allow the EFIS-D10A to be installed in aircraft covered by the STC. What is the pedigree of the Dynon EFIS-D10A? EAA and Dynon successfully demonstrated that Dynon’s commercially-proven manufacturing and development process yields a product that is suitable for use in type certificated aircraft. The Dynon EFIS-D10A is also verified against the recently developed ASTM 3153-15, Standard Specification for Verification of Avionics Systems, which Dynon Avionics was instrumental in creating. What does installation entail? The STC requires that the EFIS-D10A replace the primary attitude indicator. The EFIS-D10A requires power, pitot, static, Dynon’s GPS Antenna, and optionally Dynon’s AOA probe, remote magnetometer, and OAT. Will the EFIS-D10A fit in my panel? In a Cessna 172, the EFIS-D10A occupies a slightly larger area than the space available when a conventional attitude indicator is removed. This requires a new subpanel with slightly different spacing. Dynon expects to have turnkey installation kits available that include this panel and other installation accessories. How much does it cost to install? Initially, this will depend on the installer’s rates and experience. Based on past experience, it can take as little as a few hours to install. All-inclusive fixed pricing — including installation — from preferred Dynon dealers is under consideration. Dynon’s aircraft-specific installation kits and comprehensive installation instructions will also minimize total installation costs. Can I install it myself? The installation must be approved by an A&P. Aircraft owners who work on their own aircraft under supervision and approval with an A&P could apply this STC to their aircraft in that manner. When will the EFIS-D10A and associated STC be available? The EFIS-D10A that is customized for this STC, as well as the STC itself, are expected to be available Q2 2016. Does the EFIS-D10A that can be installed in a type certificated aircraft have the exact features as the EFIS-D10A’s available for the experimental market? They are the same product and have the same capabilities. However, there are some features that are not currently approved for use in type certificated aircraft. One of these is autopilot. How does the installation affect the Weight & Balance of my aircraft? Typically, installing an EFIS-D10A changes the total aircraft weight by less than 1 lb. Installing the magnetometer or OAT will be hard in my aircraft. Do I need to install them? You can choose to not install the magnetometer and/or OAT (the OAT connects through the magnetometer). In these installations, the EFIS-D10A will not be able to display magnetic heading, OAT, or winds. Note that your aircraft’s existing magnetic compass must remain in the aircraft regardless. The EFIS-D10A has a lot of capability. All I want is an attitude indicator. All of the other functions that the EFIS-D10A can provide are supplemental in nature. Strictly speaking, the EFIS-D10A is a replacement for your attitude indicator. All other capabilities, such as airspeed and altitude, can be suppressed. All of your other primary flight instruments are required to remain in your aircraft. There is a GPS receiver/antenna for the EFIS-D10A, but there are no mapping functions in the product. What is the GPS for? The EFIS-D10A’s attitude algorithm is normally aided by pitot-based airspeed information. If the EFIS-D10A’s airspeed source gets blocked, the EFIS will automatically use GPS ground speed to continue to display accurate attitude. The GPS antenna must be connected in an STC’d installation. Is there a gyro inside the EFIS-D10A? There are no moving parts or a conventional “gyro” in the EFIS-D10A. The attitude-sensing platform uses modern MEMS rate sensors and accelerometers. Will the EFIS-D10A be damaged by aerobatics or unusual maneuvers? No. The sensor platform inside of Dynon avionics is able to align only seconds after power up on the ground, and within 15-30 seconds in the air. Most aircraft cannot exceed the EFIS-D10A’s rate limits of 150 degrees per second of attitude change. If you do, the EFIS-D10A will automatically go into a self-recovery mode and re-align after a short period of straight and level flight — typically within 15-30 seconds. I’m not in the US. Can I install an EFIS-D10A in my type certificated aircraft? The FAA STC currently applies to aircraft governed by FAA regulations.
