Dynon D30 Touchscreen Electronic Flight Display
Have questions about the Dynon D30 Touchscreen Electronic Flight Display for your certified aircraft?
No. The D30 is only FAA approved when installed along-side an STC’d SkyView HDX system.
They’re very similar. They use the same harness/wiring and pitot/static connections. The D30 is more compact at only 3.7” panel depth. With the backup battery installed, the D30 is almost a pound lighter (but not quite, notable for weight and balance). The D30 installs into a 3-⅛” hole that is notched at the bottom of the main cutout. The D30 mounts from the front with one screw after installing the docking ring mounting bracket. The power consumption between the two is similar.
There is a non-PMA version of the D30 available in limited quantities. However, the D30 is primarily designed to be an independent backup in Dynon Certified SkyView HDX systems.
Not at this time
We will be offering a trade-in program from the certified EFIS-D10A towards the D30 once we have excess production capacity available. You can sign up now, and we will begin servicing customers as soon as we are able. Learn more here.
The D30 is designed to be a self-contained backup instrument for Dynon Certified SkyView HDX systems. There are not any plans to add additional features at this time.
The D30 is designed to be a completely independent set of flight instruments, and therefore its only connections are power, ground, pitot, and static. It does not have electronic or wi-fi connectivity to other devices or products.
No. The D30 is only FAA approved when installed along-side an STC’d SkyView HDX system.
No, the D30 does not have wi-fi connectivity.
No. The D30 is only FAA approved when installed along-side an STC’d SkyView HDX system. However, when a complete SkyView HDX system is installed with a D30, the vacuum system can indeed be removed if no other avionics require it remain.
There are no plans to add AOA capability to the D30.
No, the D30 does not have heading capability.
No, the D30’s is a set of backup flight instruments, including attitude, airspeed, altitude, vertical speed, turn rate, and slip/skid indications.
No. The D30 is only FAA approved when installed along-side an STC’d SkyView HDX system. Its functions do not have separate approval, such as TSO. Therefore, it would need to be approved for use as a backup by those third-party systems.
Yes, you can. They are both covered by the same STC.
The USB-C port is primarily designed for software update capability. It can provide computer-level USB power: 500mA @ 5V, which is not able to charge modern phones or tablets quickly.
The EFIS-D10A may be available in limited quantities. However, Dynon expects that most customers will prefer the D30. Contact Dynon Sales for more information.
SkyView HDX System
Have questions about the SkyView HDX system for your certified aircraft?
The current Approved Model List (AML) covers nearly 600 piston single aircraft. As of Dec 2019, autopilot is approved in Cessna 172F-S models and some Bonanzas. The current list of aircraft under development - which includes both piston singles and twins - can be found at Aircraft Models. To help Dynon prioritize your aircraft, visit dynoncertified.com and send us your information. We will let you know when your aircraft is added to the STC or gains autopilot approval.
Yes, even the first airplanes with Dynon Certified products installed have Dynon Autopilots installed. Although the broad Approved Model List that applies to nearly 600 aircraft does not include autopilot approval in many models, Dynon is adding autopilot approvals continuously. See Aircraft Models for the current development progress for specific aircraft models.
Dynon’s list pricing for the PMA/certified versions of its products are the same as the LSA/Experimental customers. The STC for all piston single aircraft is $2000. For complete pricing information, see www.dynoncertified.com
The EFIS-D10A serves as an independent backup to SkyView HDX. It is required by the STC, even if you opt for multiple SkyView HDX displays. It can not be substituted by other instruments.
No. The entire system, including both SkyView HDX and the EFIS-D10A, are covered by a single new STC.
The design and installation approval for SkyView HDX are both covered by the STC. There are no TSO approvals needed. Dynon Certified products are produced under PMA in our facilities near Seattle, WA.
The FAA STC applies to aircraft governed by FAA regulations. There are some countries that accept this STC as-is or via reciprocal agreement. EASA aircraft are not current approved. Contact Dynon for more information.
Installations are currently available through a network of Dynon Authorized Installation Centers throughout the US. For a current list of installation centers, visit www.dynoncertified.com. It is also possible to install Dynon Certified equipment into eligible aircraft through direct purchase when installed by a qualified installer of your choosing. See the website for more details.
In most aircraft, yes, SkyView HDX replaces all your primary flight and engine instruments. You can finally say goodbye to that unreliable vacuum pump too.
Yes. SkyView HDX is compatible with popular navigators like the Avidyne IFD series and the GTN/GNS series.
Yes, when equipped with the Dynon autopilot and a 3rd party ILS receiver or IFR GPS with precision approach capability.
Yes, SkyView does not change the aircraft certification basis or operating limitations. All of the primary flight instruments, including attitude, are fully IFR capable. To navigate via IFR, you will still need a connected IFR-approved GPS or other IFR NAV source to feed guidance data to the SkyView display.
STC installations ultimately require approval from an A&P with Inspection Authorization (IA), and will require an FAA form 337.
The SkyView displays are the heart of the system, but many of the sensors and system components, such as the engine monitoring module, transponder, ADS-B and flight instrument sensors are in separate modules that are designed for easy installation.
Yes, it can. One of the available SkyView HDX features is a 2020-compliant ADS-B Out Mode S Transponder and a compliant GPS position source.
Dynon has a variety of system configurations available to tailor an installation to your aircraft. This can include omitting some products that you choose to not install.
SkyView HDX has its own built-in autopilot capability that requires the installation of Dynon servos.
No. The certified versions are PMA’d. They are not interchangeable with Experimental / LSA products.
Dynon goes to most major aviation fly-ins and events. See www.dynon.aero/events for the full schedule.
EFIS-D10A and EFIS-D100 STC Through the EAA
Have questions about our legacy displays?
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 an 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.
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:
• EFIS Unit. Either of:
(1) 100538-000: Dynon EFIS-D10A System, Retail (Includes EFIS-D10A, 100321-000; Mounting Accessories, 100351-000; Short 7/64 Hex Wrench,100556-000)
(2) 100534-001: EFIS-D100 with Super-Bright Screen, Instrument only, Retail (Includes Instrument,100488-001; 7/64 Hex Wrench, 100556-000)
• 100096-000: Dynon Internal Backup Battery for D10/D100 Series
• 102827-000: Dynon GPS-251 GPS Receiver/Antenna Module for D10/D100 Series
• 100323-000: Dynon EDC-D10A Remote Compass
• 100433-001: Dynon OAT Probe for D10/D100 Series (requires EDC-D10A)
• 100141-000: Dynon AOA/Pitot Probe, Unheated
• 102832-000: Dynon Simplified Wiring Harness for D10/D100 Series w/ GPS-251 support
• 100422-000: D100 Series Mounting Tray (although technically “optional” for the STC, The D100 requires this mounting tray for all practical purposes.)
• 100024-000: D10 Series Flush Mount Bracket
• 102813-000: AOA/Pitot Mount Bracket
The STC costs $100, and is available from EAA.
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.
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.
As of January 2017, the the expanded EAA STC Approved Model List allows for installation in Beechcraft Bonanza, Debonair, Musketeer, Sundowner Sierra, and Skipper models; Mooney M20; Maule M-4/5/6/7/8; Grumman AA-1/AA-5; Cessna 150. 152, 170, 172, 175, 177, 180, 182, 185, 205, 206, 210; Piper PA-24, PA-28, PA-32, and PA-38. Check the AML for your aircraft.
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.
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.
- 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)
The STC allows the EFIS-D10A or EFIS-D100 to replace your primary attitude indicator, or it can be added as a backup/secondary. 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.
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.
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.
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.
The Dynon EFIS-D10A or EFIS-D100 may be used either as primary instrumentation or as a backup. This can allow pilots of aircraft where a specific primary attitude indicator is needed for other systems - such as autopilot - to still install a Dynon EFIS as a backup.
The STC is available now from EAA. Eligible Dynon products are currently available from Dynon and its dealers.
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.
Typically, installing an EFIS-D10A changes the aircraft weight by less than 1 lb.
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.
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.
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.
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.
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.
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.
The FAA STC currently applies to aircraft governed by FAA regulations.
The STC does not specifically cover this scenario, but it was not intended to preclude it. Check with your IA to see if they can approve such an installation.
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. If your aircraft does not require a DG, you may be able to remove it and your vacuum pump after you install a Dynon EFIS under EAA STC.
If that equipment is required for IFR flight and/or is part of the type certificate, generally not. However, if an installed directional gyro is not required equipment per your aircraft’s type certificate, it can be removed (whether or not you are installing a Dynon EFIS). After you remove your DG and install a Dynon EFIS under this STC, your vacuum system may not be connected to any instruments. If this is the case, it can be removed too.
