Flying with Avidyne’s version 10.2 software

If you think updating the software on your phone is hard, try it with avionics.

Avidyne has been promising a new release of the software for their IFD line of WAAS GPS units for a while now. Originally announced on April Fool’s Day last year, version 10.2 packs a pretty impressive list of features, including synthetic vision, support for a bunch of new devices (including digital radar and FLIR cameras), display of more ADS-B weather and traffic data, and a new “IFD100” iPad app that essentially acts as a second screen for your IFD. They generously made the update available for free, but with a catch: it has to be installed by an avionics shop. The FAA lets aircraft owners make “minor repairs and alterations” (a phrase which has a very specific set of parameters around it), and avionics software updates aren’t considered “minor.” When they finally announced that 10.2 was available, the first order of business was to find a shop to install it. None of the local shops are Avidyne dealers, so we decided to head back to XP Services in Tullahoma. A quick phone call to schedule an appointment was all it took.

The flight to Tullahoma was pleasant, and the XP team had the upgrade done in about 2 hours– right about the amount of time Avidyne says it should take. The update procedure is very detailed and specific, with lots of dire warnings about what happens if you do it wrong, so I’m glad they didn’t. They also upgraded the software in our SkyTrax 100 ADS-B receiver, which will become important a little later in the story. I can’t say enough good things about XP’s staff: they did good work, quickly, at a fair price, and were very friendly. Be forewarned if you go there though: there are no vending machines nearby so bring your own snacks.

On the way home I got to start playing with the new features, but it wasn’t until last week’s Easter trip from Decatur to New Smyrna Beach that they really came into their own. Here’s a partial list of the new goodness in this release.

Let’s start with synthetic vision. The IFD540 doesn’t have a way to sense the attitude of the airplane, so its syn vis feature is limited to showing a “plane in trail” (Avidyne calls it exocentric) view of you, your route, and the surrounding terrain. In this case, I’ve programmed the ILS 18 Y approach into my home airport. You can see the magenta line indicating that I’m on the final approach segment. The white line-and-loop to the upper right is the missed approach procedure that I’d fly if I couldn’t land. There’s another airplane in the area, at 1900 feet and descending. The synthetic vision display makes very clear what the surrounding terrain and obstacles look like, and how my planned flight path would interact with them. This is not a huge deal in the flat riverine terrain near Decatur but in someplace like Montpelier, with more significant terrain, it could literally be a lifesaver.

heading for the approach

Another nifty new feature: temporary flight restrictions (like the one shown below, for firefighting in southern Georgia near Waycross) and winds aloft data (the little white flag-looking things in the second picture) can now be shown along with all the other flight data. You can see that we have about a 20kt headwind. It’s important to remember that, like all other ADS-B weather data, the wind data comes from the ground and may not reflect what’s truly happening in the air at that moment.

Don’t fly in TFRs unless you want to meet the FAA in person

The direction of the wind barb shows which way it’s blowing; the number of little flags shows how strong it is

Traffic display is greatly improved in two ways. First, you can now see trend lines showing you where a traffic target is going (along with its N number, if it’s transmitting one). This is really helpful in crowded airspace, like the area around the Daytona Beach airport. You can see that both airplanes on the display are headed in the same direction as we are, one at roughly our same altitude and the other descending.

In 10.2, you can see where traffic targets are going

I also now get traffic alerts when there’s a potential conflict, i.e. someone else is flying towards me. An aural alert (“bong! TRAFFIC”) comes first, then the screen changes to show the conflicting traffic. This is an extremely valuable feature.

When you hear “TRAFFIC,” you’d better start looking around

The IFD100 app does what it promises: it lets you control the physical IFD, but it also lets you configure its display completely independently of the one on the panel. It does about 80% of what the “real” IFD hardware does. For example, you can load a flight plan into the iPad app while the panel is showing you the map/weather/traffic page, then push a button and activate that flight plan from the iPad. You can see and tune frequencies (but not activate them), zoom in and out on maps, and in general act like you have a second IFD540. It’s pretty neat, although there are some quirks to it that I’m still figuring out.

Not quite a replacement for Foreflight

The IFD100 app isn’t a replacement for FlyQ or Foreflight though; it doesn’t let you anything that the physical IFD can’t do, so no looking up fuel prices or FBO reviews, no satellite imagery display, and so on. ForeFlight has all sorts of useful planning features like terrain mapping, wind estimation, and flight plan filing that the IFD100 doesn’t, and won’t. I don’t think Avidyne intends the app to replace a true electronic flight bag (EFB) app, but rather to give you more options and flexibility with using the in-panel hardware.

I haven’t been able to test one of the signature features of 10.2 yet, though: its ability to do two-way sync over Wi-Fi between the panel device and a tablet. I can already stream a flight plan, and GPS position data, from the IFD to ForeFlight or FlyQ. 10.2 adds the ability for the IFD to send traffic, weather, and TFR data (which means I won’t need my Stratus receiver to see that stuff in ForeFlight), but also the ability to load a flight plan from the iPad to the panel. That means I can plan a complex route at my leisure in my armchair, file it, brief it, get my expected route, and push the route to the airplane when I get to the airport with a single button press. That’s going to be glorious when it finally arrives.

It speaks well of Avidyne that they made this major feature release available for free, and I’m excited to see how they continue to build on the wireless connectivity built into the IFD line.

    Foreflight has not updated their software to enable the ability to transfer your flight plan from ForeFlight into your IFD despite 10.2’s ability to do so. Also it does not allow the ability to see traffic and weather in Foreflight yet. I certainly hope Foreflight will get on the ball and have this out in the next release.

      They still haven’t. I can see why they wouldn’t be in a hurry given that, with that capability, there’s no real reason to buy a Stratus, but I wish they’d hurry up.
