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

Dynon plans to offer (what we now call) the "Gen 1" products for the foreseeable future. Many current and potential 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.

What new features are, and will be included SkyView?

The most notable differences between SkyView and Dynon's "Generation 1" products are that SkyView offers a 10" display, SkyView offers synthetic vision and moving map, most recently, a transponder option. SkyView offers considerably more expansion and redundancy than Dynon's Generation 1 products. Considering that SkyView is only 1 year old, its progress is remarkable.

Near term, Dynon's priority for SkyView feature implementation is to achieve full feature parity with Dynon's "Generation 1" products, including audible warnings, and to complete SkyView's map and synthetic vision features.

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 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 Installation Guide is available for download. (This is the full installation guide furnished to purchasers of SkyView).

What is the screen resolution of the SkyView displays

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

When installing the SV-ADAHRS-200 / 201, how should it be oriented in the fuselage? Connector forward like the remote compass for the original Dynon products?

As SkyView originally shipped and to date, the SV-ADAHRS-200 / 201 must be oriented with the pneumatic ports forward. A future SkyView software update will allow the SV-ADAHRS to be reversed so that the pneumatic ports can be orientated towards the tail.

Will all of the SkyView modules use the DSAB as the communication network?

SkyView Network is Dynon's next generation avionics bus that is redundant and much faster than DSAB. Because of these enhanced capabilities, Dynon's "Generation-1 products cannot interoperate with a SkyView Network.

Dynon autopilot servos are the only Dynon product* that will work with both the "Generation 1" systems 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 Generation 1 and SkyView.

  • Well, technically, harnesses for the EMS-D10, EMS-D120 and EMS connector of the FlightDEK-D180 will also work with the SV-EMS-220.

Will the HS34 and the AP74 become obsolete for this new architecture or will they still be required/complement the new system?

Because SkyView displays have knobs/joysticks, the enhanced controls available on the HS34 and AP74 aren't needed for SkyView.

Does the SkyView radio/transponder interface only work with the planned Dynon Comm and Nav radio products, or continue to work with radio's such as the SL-30 and the G430W?

The SV-ARINC-429 module works with some external radios (like the SL-30), and longer-term compatibility with other products will be added.

Is the plan to bring SkyView up to the ability to create a fully redundant system in regards to dual ADAHRS, dual networking, etc along with redundant serial port inputs to redundantly support external data sources in a dual screen setup if one screen dies?

As originally shipped, SkyView can use redundant ADAHRS (SV-ADAHRS-200 is primary, SV-ADAHRS-201 is secondary). "Dual Networking" is also a capability as SkyView originally shipped (the SkyView Network wiring includes redundant data and power). All serial devices can simultaneously "feed" multiple SkyView displays; if one display fails, the other displays will continue to receive serial data.

Will the serial interfaces for externals be on the SkyView Displays or in a separate black box behind the panel?

Each SkyView Display has 5 serial ports (one of which is intended for use for the Dynon GPS Receiver).

What will drive the FD, HITS, ext? Are you going to be adding flight planning, synthetic approach capability and AP sequencing features similar to some of the competition or is all of this stuff going to be driven strictly by external data sources?

Over the long term, yes to all of those. SkyView shipped with only a basic moving map feature, and progressively more advanced moving map capabilities have, and will continue to follow. The long-term plan is to do full IFR flight planning (of course, you'll need a certified GPS source like a 430 to actually file /G and generate guidance that can be legally followed). External data sources will be secondary goals for us, not the primary source.

Will you have a GPS option to drive the map and all the other GPS driven features?

Yes, the SV-GPS-250 GPS Receiver will be available at the same time all the other SkyView products are initially available.

Which of the current probes / accessories / brackets will be compatible with the next generation?

For those of us with existing engine monitors from Dynon, will the new generation products be backwards compatible with the connector and sensors?

COMPATIBLE: All engine and temperature probes, AOA/Pitot probes, Autopilot servos, encoder converter module

NOT COMPATIBLE: EDC-D10A remote magnetometer, mounting brackets and trays, expansion modules (HS34, AP74 - see below for details)

Engine harness pinouts are expected to remain the same*, but primary wiring harness pinouts will be different.

  • 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.

What if someone wants the new system plus a D10A? Or, you have a D180 and want to display engine info on the new screen?

The EFIS-D100, EMS-D120, FlightDEK-D180, EFIS-D10A, and EMS-D10 will all still be for sale for the foreseeable future. We are not canceling any of our current products. Over time, the D100, D120, and D180 will likely phase out in favor of the next generation system equivalents, which will have all of the same capabilities and much more.

All of our 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 years, and we'll still help with any question or problem you may have.

That being said, we are going to be winding down new feature development on the current series of products after the autopilot is released. We've pretty well reached the limits of what we're able to do with the computing power in the current 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.

We've also learned a lot with the last 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. For example, making DSAB work between the current and new products would be a huge software effort. If we put our limited resources there, development all of our products would slow down, and we're already a busy bunch over here.

We believe there's an easier way to cross the compatibility border, and that's the offer for trading up credit on old units. If you are interested in the new system, then we'll take what you have and give you credit towards the next system. It's win-win: you get the new system, a new warranty, and we get to focus on our new product development.

We think that this trade-in program is a type of support that is uncommon in fast-moving technology (will Apple give you credit for your 2 year old iPod, or Dell for your old laptop?), but we want to do it anyway. We really do appreciate all of your business, and we want you to continue to grow with us. What's better than being sure that your past financial investment will continue to be an investment in the latest products from Dynon?

Will the Moving Map/GPS functionality be an add-on to existing Dynon systems with the addition of a next generation screen and the corresponding module?

Unfortunately, the D10A/D100 series does not have the computing horsepower required to be able to offer a map, nor the user interface that we think is required (the next generation has a joystick to pan around the map). As mentioned above, feature development on our current generation or products will wind down as we concentrate our resources on our next generation of avionics.

How about an interface with satellite WX receivers?

We will have weather at some point, but we can't promise compatibility with a specific device yet.

Where will the pitot/static lines connect?

The pitot/static lines will go to the ADAHRS box.

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?

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.

I have a D100 and a D180 (two ADAHRS) with an HS34 module and AP servos that I plan to keep. Not knowing the details of your design, will I be able to just add a SkyView screen and your GPS receiver to incorporate the moving map functions and complement my existing instruments, or will I have to also add a third ADAHRS with the NG hardware to incorporate the moving map functions?

To display ADAHRS data on a SkyView display requires a SkyView ADAHRS module. To display maps, SkyView displays require GPS data.

Will the next generation ADAHRS be less dependent on pitot aiding than the current versions?

Version 5.1 (and later) of the "Generation 1" products added GPS assist. Using version 5.1 with a GPS connected, GPS ground speed can be 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 is also a feature of SkyView.

How do I wire SkyView autopilot servos?

Autopilot Servos have seven leads. Four leads should be connected to two sets of twisted-wire pairs, 22 gauge or larger, and be spliced into the nearest SkyView Network connection. A SV-NET-SPL can be used for this. Two other leads are to be connected to appropriately-sized Power and Ground wires, and connected to the main aircraft electrical bus with the correct circuit breakers or fuses. The final lead needs to be connected to a quick-disconnect switch on the aircraft control yoke or stick. Dynon offers the SV-NET-SERVO wiring kit, which includes 20 feet of appropriate wire and SkyView-compatible connector.

Does Dynon sell antennas and the antenna cable(s) for the new Dynon 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 (revision E for software v2.6) has a new section on the installation of the transponders, including some information on selection, placement, and installation of transponder antennas and the antenna cable.

Does Dynon have any plans to allow the SkyView system to integrate with Vertical Power's new VP-X system? For what it's worth, I'd REALLY like to see it happen.

SkyView doesn't output this data now, and it isn't on our short term development schedule. However, we are demand driven in our priority list, and will continue to evaluate that feature. If 20 other people show up and ask, that could of course sway us.

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

If a SkyView Display has master power, pushing and holding buttons 1,2 and 5 will reboot it.

What does the blinking red light on the SV-ADAHRS-200/201 and SV-EMS-220 mean?

The red indicators on the SV-ADAHRS-200/201 and SV-EMS-220 blink when they are powered up and operating normally. The blinking does NOT necessarily indicate that the modules are communicating on the SkyView Network.

I'm retrofitting a SkyView into a Glastar with circa 2002 stuff. I've got a old Navaid wing leveler that can fly a GPS track but am going to need 4800 baud 8,N,1 GPRMB and GPRMC sentences out from the SkyView to drive it (yes I'm planning on you being the only GPS). Is that on the list for the mapping module because I really don't want to add a Garmin to the panel and enter goto on both systems just for that?

NMEA output for SkyView is planned, but we don't have a firm date or release when it will be available.

So, if I need GPS data out of the SkyView system before the NMEA data out is available, can I just tap off the Dynon SV-GPS-250 output?

Yes, but to handle the 5 Hz update rate, the SV-GPS-250 outputs data at 38,400 bps, so anything you're going to connect needs to be able to handle that data rate.

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 SkyView Installation Manual will be updated to emphasize this point.) 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.
