Dynon Avionics' best-selling EFIS-D100 is now STC approved for installation in type certificated aircraft.

HOW TO PURCHASE YOUR EFIS AND STC
The EAA's STC specifies out a Commercial Parts List, specifying part number 102778-000 (EFIS-D10A EAA Sales Kit), which is the super-set of acceptable components for installing a Dynon EFIS in eligible aircraft . This part is not orderable itself. Per the Instructions for Continued Airworthiness (P/N TJJ-MAN-01) for the EAA STC, some components are required, while some are optional. As of August 2016, those are:

How am I able to put a Dynon EFIS-D10A or EFIS-D100 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 a Dynon EFIS as a replacement for the primary attitude indicator in small GA aircraft. The EAA — with Dynon’s help — developed the STC. Customers buy the Dynon EFIS from their Dynon dealer/installer and the STC from EAA. Like any STC, installations must be signed off by an A&P with Inspection Authorization (IA) and will require an FAA form 337.

What is the pricing and availability of the EFIS systems configured for these applications?

Because of the novel approach of the EAA’s STC, pilots of type-certificated aircraft will install the same commercial EFIS instrument that is available for experimental and light sport aircraft. Therefore, pricing is the same as well. The EAA STC specifies part number 102778-000, which is the super-set of acceptable components for installing a Dynon EFIS in eligible aircraft. Per the Instructions for Continued Airworthiness for the EAA STC, some of those components are required, while some are optional. As of August 2016, those are:

Who is Dynon?

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 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.

To confirm that your particular aircraft model and type certificate is eligible, check the EAA STC Approved Model List.

Your aircraft must have been equipped with a pneumatically driven attitude indicator at time of manufacture to be eligible.

Is the EFIS-D10A / EFIS-D100 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 products?

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 and EFIS-D100 are also verified against the recently developed ASTM 3153-15, Standard Specification for Verification of Avionics Systems, which Dynon Avionics was instrumental in creating.

Will the Dynon EFIS fit in my panel?

• The 7” EFIS-D100 is 6.95” wide x 4.90” tall x 4.51” deep.
• The 4” EFIS-D10A is 4.09” wide x 3.39” tall x 6.85” deep (standard hole mount) OR 7.64” deep (optional flush mount)

What does installation entail?

The STC allows the EFIS-D10A or EFIS-D100 to replace your primary attitude indicator. It can also be installed as a second attitude indicator in aircraft that already have one installed. The EFIS-D10A requires power, pitot, static, Dynon’s GPS-251 Receiver/Antenna, an internal backup battery, and optionally Dynon’s AOA probe, remote magnetometer, and OAT.

Will the EFIS-D10A or EFIS-D100 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.

How much does it cost to install?

Initially, this will depend on the installer’s rates and experience. The EFIS-D10A was originally designed to be installed by aircraft homebuilders with minimal experience, so professional installers will be impressed by how easy it goes in. The aircraft that EAA used for FAA acceptance tests was converted to the STC configuration, test flown, AND converted back to its original form all in just days. Some aircraft will need to have existing instrument spacing modified. This will require a new panel.

Can I install it myself?

STC installations ultimately require approval from an A&P with Inspection Authorization (IA), and will require an FAA form 337. Aircraft owners who work on their aircraft under the supervision and approval of an appropriately rated mechanic could apply this STC to their aircraft in that manner.

When will the EFIS-D10A, EFIS-D100, and associated STC be available?

The STC is available now from from EAA. Eligible Dynon products are currently available from Dynon and its dealers.

Do the EFIS systems that can be installed in a type certificated aircraft have the exact features as the EFISes 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 aircraft weight by less than 1 lb.

The Dynon EFIS will not fit in my panel. What can I do?

You must maintain the “six-pack” orientation of your existing primary flight instruments. In other words, you can not rearrange them. You may, however, use a new panel to change the spacing to accommodate the EFIS.

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.

This EFIS 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, 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?

There are no moving parts or a conventional “gyro” in the EFIS-D10A or EFIS-D100. The attitude-sensing platform uses modern MEMS rate sensors and accelerometers.

Will the EFIS 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’s rate limits of 150 degrees per second of attitude change. If you do, the EFIS 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 a Dynon EFIS in my type certificated aircraft?

The FAA STC currently applies to aircraft governed by FAA regulations.

Can I add a Dynon EFIS to an aircraft that was not originally shipped with -- or does not have -- an attitude indicator?

Not under the STC, but contact the EAA and they may be able to work with you on a field approval.

Can I add an additional EFIS-D10A to replace my DG/HSI?

No. Right now the STC only allows the EFIS-D10A to be used as an attitude indicator. However, you can add a second attitude indicator elsewhere in the panel if you’d like. The STC does not restrict the number of attitude indicators installed in your aircraft.

Additional Information

High Resolution Screen
The EFIS-D100 features a 7" diagonal, color LCD which boasts the highest resolution in its class. The stunning display enables split-screen viewing to augment the primary EFIS data with other pages of information called up by the pilot. Six buttons arranged along the bottom of the screen serve as the interface to the softkey-driven menu system for easy access to in-flight functions and setting pilot preferences.

Advanced ADAHRS
Dynon's advanced ADAHRS (Air Data, Attitude and Heading Reference System) integrates over a dozen solid-state sensors that deliver exceptional performance and reliability. With the exception of the remote compass, the ADAHRS is built inside the EFIS-D100 instrument housing, saving installation time and space. Each ADAHRS undergoes a rigorous calibration regime at the factory to ensure accuracy over its full operating range. Unlike mechanical gyros, Dynon's rugged design is tolerant to aggressive flight maneuvers, automatically corrects itself anytime its gyros' capabilities are exceeded, and cannot be damaged by aerobatics or unusual attitudes.

Reliable Operation
Dynon's EFIS-D100 utilizes an embedded, multi-processor design that delivers real-time performance and stability. This purpose-built design is unencumbered by burdensome operating systems that typically slow down performance and require long boot times. Dynon's software design enables complete control to maximize execution speed and deliver robust reliability. A hallmark of the EFIS-D100's performance and a great safety feature is its ability to display the correct attitude within a few seconds of being powered on while in flight.

Safety Features
A unique safety feature available from Dynon is its optional AOA/Pitot that combines Angle-of Attack (AOA) and airspeed sensing into a single pitot design. The AOA capability assists pilots on approaches and generates an alert signal for audible annunciation whenever nearing stall conditions. This pitot is available in heated and non-heated versions.

To guard against a power failure scenario, the EFIS-D100 may be optionally equipped with a Li-Ion Backup Battery. When power loss is detected, the instrument will automatically notify the pilot and immediately begin running on battery power for a minimum of 1.5 hours, enabling a safe landing.

Connectivity
The EFIS-D100 is equipped with a PC serial interface which provides the capability of uploading up to 25 user-defined lists for use as checklists, aviation data or other information that pilots wish to keep handy. The PC interface additionally facilitates downloading free firmware updates from Dynon's website.

Cockpits equipped with more than one type of Dynon instrument can benefit from the connection capability that comes via the Dynon Smart Avionics Bus (DSAB). When linked via DSAB, pages displayed on one instrument may be shared for display on other Dynon instruments. DSAB not only allows you to share the fun with your co-pilot but delivers Dynon generated data directly to the instrument in front of you whenever you call upon it.

Expandable
Dynon has developed a series of expansion modules that add new capabilities and functionality to its existing line of D10/D100 Series EFIS, EMS and FlightDEK avionics. These optional modules provide exceptional value and performance while preserving the affordability of Dynon's existing equipment. This modular concept promotes greater flexibility when configuring new aircraft panel systems and facilitates future expansion if so desired.

Each expansion module is network connected to its line of avionics via the Dynon Smart Avionics Bus (DSAB). This two wire connection not only simplifies wiring but can extend individual module benefits to multiple interconnected Dynon instruments.
