Note: This FAQ was begun to answer questions about the announced, but not-yet-shipping SkyView system (before it was even named) prior to SkyView being released for sale in December, 2009. Many "what-if" questions have been gradually pruned out because they are now definitively answered in the SkyView sales information, Pilot's User Guide, and System Installation Guide.


Is / will SkyView be certified / TSO'd?

Within the immediate future, no. Eventually... maybe. The SV-XPNDR-261 and -262 are certified / TSO'd.

What is required / what do I have to buy to have a SkyView IFR system?

(To be added)

What is the status of SkyView terrain / obstacles / maps database, especially for worldwide?

All SkyView-related files can be downloaded here.

The Navigation Mapping Software in SkyView firmware version 3.2 (released September 21, 2011) is considered to be largely feature-complete. There will be continuous enhancements to the Navigation Mapping Software, especially better handling of waypoints.

  • Terrain
    • Every* SkyView display has included a low-resolution terrain database of the entire world. This database should not ever require updating.
    • SkyView displays* shipped since approx. March, 2011 (firmware v3.0) has included a very-low-resolution terrain database of the entire world. This database should not ever require updating. SkyView displays shipped prior to March, 2011 can add this database.
    • SkyView ships (from the factory - non-US dealers and OEMs often change this) with a high-resolution terrain database of North America, but can be easily updated for other regions (warning - it's a big file - use a high-speed Internet connection).
  • Map - including Aviation / Obstacles Database(s)
    • Every SkyView display ships with the Navigation Mapping Software enabled, as a demonstration, for 30 flight-hours.
    • After 30 flight-hours have elapsed, to continue using Navigation Mapping Software, the SV-MAP-270 Navigation Mapping Software License must be purchased and installed on one SkyView display.
    • US customers can download free Aviation and Obstacles databases from Dynon. These database are updated every 28 days.
    • Non-US customers must contact Jeppesen for Aviation and Obstacles databases for areas other than the US.
    • Dynon is working with other sources of Aviation and Obstacles databases, especially for Europe, but as of this update, there is nothing to announce.
    • SkyView displays shipped since approx. September, 2011 (firmware v3.2) have included a "Base Map". The initial version of the Base Map included country borders and US state and Canadian province borders. The Base Map will be periodically updated with more data and thus should be updated periodically.

* Exception - Dynon does offer a version of SkyView without the terrain database included for special applications, thus the terrain database is, technically, an optional feature.

Will Dynon keep making the D6/D60 and D10A/D100 Series of products?

What if someone wants to buy SkyView plus an EFIS-D10A? Or, you have a FlightDEK-D180 and want to display engine info on the new screen?

Will the Moving Map/GPS functionality be an add-on to existing Dynon systems with the addition of a SkyView-type display?

Dynon plans to continue to offer the:

  • EFIS-D6
  • EFIS-D10A
  • EFIS-D60
  • EFIS-D100
  • EMS-D10
  • EMS-D120
  • FlightDEK-D180

for the immediate future. Many customers want just the simplified feature set of the D6/D60 and the much more complete feature set of the D10A/D100 products. The size and form factor of the D6, D10A, and EMS-D10 make them ideal replacement instruments in existing panels. However, we've pretty well reached the limits of what we're able to do with the computing power in these products. The major features that our customers have been asking for - such as synthetic vision, moving map, thin screens, etc - are not features that we can implement on our current hardware... though we may have one last big surprise.

Over time, the EFIS-D60, EFIS-D100, EMS-D120, and FlightDEK-D180 will likely phase out in favor of SkyView equivalents, which will have all of the same capabilities and much more.

All of these Dynon products will be supported for years - with repairs, technical support, and any bug fixes that are needed. There is no way that Dynon would ever stop supporting a past customer. We think one of the reasons we've been successful is that we've tried our best to support all of our customers, and that will continue to be the case. Call us with a question or a problem on an EFIS-D10, a product we haven't sold for over 3 4 5 6 7 years, and we'll still help with any question or problem you may have.

We've also learned a lot with our generation of products, and to remain competitive we need to take all of that knowledge and translate it into the best avionics we can possibly build. To do this effectively and efficiently, we have we have to draw some lines between what we have now and what we'll be building next.

To ease the transition between Dynon's earlier products and SkyView, Dynon offered a trade-in program, which ran for a year, was extended an additional six months, and was concluded in June, 2011. During the 18 months the trade-in program was available, few customers used it because, to their delight, they found that the value of their used Dynon equipment held up very well and they were able to sell them for more than the Dynon trade-in program.

What new features are, and will be included SkyView?

Dynon provides an online features table that details which features are already present in SkyView, which are in development, and which are planned for future implementation.

Other products seem to offer similar functionality to SkyView; why should I buy SkyView?

Comparing screen shots of SkyView against the competition can show you a lot in many cases. Some of the competition's displays are severely limited by blocky, low-resolution, low frame-rate graphics that don't feature the color depth that SkyView offers. Look at the fidelity and legibility of the moving map and synthetic vision in particular. Unlike most of the other products on the market, SkyView is built with modularity in mind. This will let you add features through module additions as your needs change and budget permits. This modular approach also means that in the unlikely event that you experience a problem with your product, you won't need to send the whole system back for repair - only the affected module need be removed. And of course, you can expect the Dynon pricing, performance, and reliability. Dynon products are designed, assembled, and supported here in the US.

Is the 7" version (SV-D700) of the SkyView display the same size as Dynon's D100 series?

Not quite. The cutout needed for the SV-D700 display is bigger than the current D100 series, so panel modification will be required for retrofits. Also, SkyView displays mount directly into the panel (no mounting tray like the D100 series). The Skyview Panel Planner is available for download, and full dimensional (and technical) information is available in the latest SkyView System Installation Guide.

What is the screen resolution of the SkyView displays?

SV-D1000 resolution is 1024x600 pixels. SV-D700 resolution is 800x480 pixels.

Can SkyView interoperate with Dynon's earlier products?

Which of the current probes / accessories / brackets are compatible with SkyView?

For those of us with existing Dynon EMS units, will SkyView EMS be backwards compatible with the connector and sensors?

Can you use an AP74 or HS34 with a SkyView system?

SkyView Network is Dynon's next generation avionics bus that is redundant and much faster than DSAB. Because of these enhanced capabilities, Dynon's earlier products cannot interoperate with a SkyView system.

Dynon autopilot servos are the only major Dynon product that will work with both Dynon's earlier products and SkyView. Servos that are already installed can be upgraded in place to work with SkyView (or sent back to Dynon for upgrade), and servos shipped as of December 1, 2009 will work with both Dynon's earlier products and SkyView.

  • All engine and temperature probes
  • AOA/Pitot probes
  • Autopilot Servos
  • Encoder Converter Module
  • Capacitive to Voltage Converter Module
  • EMS harness*

* While you can plug an existing EMS-D10 / EMS-D120 harness into a SV-EMS-220, the SV-EMS-220 makes use of some pins differently. One example is that the serial port pins used for the EMS-D10 / EMS-D120 are general purpose inputs on the SV-EMS-220; these changes are thoroughly explained in the SkyView Installation Manual. You may also have to remove some inline resistors that were required for the EMS-D10/EMS-D120/FlightDEK-D180.

  • EDC-D10A remote magnetometer
  • Mounting brackets and trays
  • HS34
  • AP74
  • EFIS harness

One of the things that attracted me to the existing Dynon product line is that Dynon has its own dedicated RTOS-like software stack. Some other vendors use commercial OSes like WinCE which makes me a bit uncomfortable. What is general architecture of the new software platform?

Since SkyView is running an Operating System (OS) - however much it's "compact, optimized, stabilized"... can it be "rebooted"?

SkyView runs a compact, optimized, stabilized Linux kernel for the display. The remote boxes like the AHRS, EMS, servos, etc still run with no OS, and the screen is managed by a no-OS micro.

A SkyView can be rebooted by pushing and holding buttons 1,2 and 5.

Is the SkyView SV-ADAHRS-200/201 less dependent on pitot aiding than the earlier Dynon EFIS'?

Beginning with v5.1, the EFIS-D60/D10A/D100/FlightDEK-D380 products added GPS Assist. With a GPS connected, GPS ground speed is automatically substituted for airspeed when the EFIS detects that the airspeed indication has failed (usually because of an iced, blocked, or otherwise disconnected pitot). When this happens, the EFIS annunciates that its attitude indication is in a “GPS Assist” mode. The EFIS 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 Dynon EFIS systems continues to be accurate.

GPS Assist was included in SkyView at its initial release.

Does Dynon sell antennas and the antenna cable(s) for the SV-XPNDR-261 and -262 transponders?

Dynon does not (currently) sell either the coaxial cable or an external antenna required for the transponders. You will need to purchase these items from an avionics supply company such as > Aircraft Spruce. The SkyView Installation Guide has a section on the installation of the Dynon, including some information on selection, placement, and installation of transponder antennas and the antenna cable.

Why does Dynon recommend the more expensive SV-XPNDR-261 vs the SV-XPNDR-262?

Dynon has been told that the higher performance of the SV-XPNDR-261 will eventually be required for US pilots. There will obviously be a long phase-in of this requirement, but as soon as Dynon became aware of of this issue, Dynon began recommending the SV-XPNDR-261 for US pilots.

Can the Skid/Slip Ball Be Adjusted Electronically as part of SkyView setup?

No. The SV-ADAHRS-200/201 is factory-calibrated to reflect level. If your SkyView installation's Slip/Skid Ball doesn't indicate level, try checking the "levelness" of the SV-ADAHRS-200/201 with a DIGITAL level (that can display 1/10th degree increments).

When installing the SV-EMS-220, should I connect one ground pin to the Engine ground?

Yes! The SV-EMS-220 is measuring voltage differences as small as millivolts (mV) - thousandths of a volt differences, so providing the SV-EMS-220 with a ground reference as close as possible to the sensors will result in more accurate sensor readings.

Does SkyView need to be powered up for the SkyView backup battery to charge?

Yes. SkyView's software manages battery charging, so the SkyView Display has to be running for the respective battery to get charged (one battery per display).

Does the SkyView provide a way of recording data for later analysis in Excel/Matlab/other for us uber-geeks (i.e. maybe storage to a FLASH disk inserted in the USB socket on the display’s wire harness?)?

As of SkyView firmware v3.2, the only recording capability in SkyView is an internal log file for Dynon Avionics Engineering use. However, SkyView can stream both flight and engine data from a serial port, and that data can be recorded with an external unit - either a laptop computer or a dedicated data logging device (Google for "data logger"). Data logging is a capability that will be added in a future (but near-term) update of SkyView firmware.
