In flight, Xavion constantly imagines engine-failed glides to every runway in gliding range, and then shows you the safest-possible route as Highway-In-The-Sky to take in the event of engine failure. This, finally, gives you guidance after an engine failure that is based on energy-management all the way down, where the computer does the glide-planning for you… you just fly through the hoops to the runway.

As well, Xavion tracks other airplanes via ADS-B, and memorizes their location to track their WAKE TURBULENCE, moving the wake turbulence down and with the wind over time, and showing the wake turbulence as little spiraling tornados. Finally, an App that tracks and shows you the wake turbulence of other airplanes.

As well, Xavion gets ADS-B weather (if you have a Sagetech or iLevil receiver) and shows it on a moving map, and provides weather for all airports that report it. As well, Xavion gets METARS and winds aloft from the internet if you have a WIFI or cell signal before or during flight!

Also, Xavion checks your weight and balance, medical and BFR currency, and even estimates your takeoff distance and compares that to the length of the runway that you are about to take off on to warn you if the available length from your current location on the runway is too little for a safe take-off.

Also, Xavion estimates time and fuel burn at all different altitudes to any destination you want to go to, and shows you 3-D “highway in the sky” hoops to get there.

Xavion is free to download, and requires In-App purchase of current airport data ($9.99/month, or $99.00/year). As well, you may OPTIONALLY by a Seattle Avionics Chart Data subscription for $149.00/year, or access your EXISTING Seattle Avionics Chart Data subscription freely.

This is the most user-friendly, powerful App that I can imagine, and I love flying with it.

(We never release customer info, and the terms of use are listed at the launch of the App. Continued use of GPS running in the background can dramatically decrease battery life.)

What's New

Version 1.88

New for Xavion 1.88:

In addition to full Stratus support and an overhauled internal AHRS system for iPad-based attitude, we now have support for THE NEW ADS-B WEATHER PRODUCTS!
Lightning, cloud tops, icing, and turbulence!

Here is how it works: There is now just a SINGLE weather option in the SETTINGS page called WEATHER.
Once that single option is turned on, then in the MAP screen of Xavion, just a FEW buttons show up in the lower-left, but each one DOES a LOT!


Just five buttons! That's it!
And just these five simple buttons display ALL of the ADS-B weather, including the new weather products that just came out this year!
Here is how we get the ENTIRE suite of new ADS-B weather with just five little buttons:

THIS is the button you hit when you are flying around storms!
This shows NEXRAD precip, and also the clouds around the precip so you can see how far out the clouds go from the storms, AND all of the lightning strikes in the area! All of this info is easily plotted at the same time, and is all relevant to summertime flying: This is what lets you avoid storms! Hit one button and you have all the weather you need to avoid thunderstorms and other types of heavy precip.

For those flights where ICING is you concern, just hit this ONE BUTTON!
This shows the icing forecast from the NOAA at all altitudes from 2,000 to 24,000 feet.
As well as the icing severity and risk forecast, I also lay a cloud map over it so you can see where the visible moisture is (ice can only form in visible moisture!) and I throw down the freezing level as well so you can get a quick-look at how low you have to limbo to get out of the ice in the descent! This is especially cool because the ADSB broadcast does NOT include the freezing level!!! (WHUUUUUUUUT?) Yep, they never send the freezing level, but I still show it to you! How? Easy! ADSB DOES broadcast winds and temperatures aloft, so Xavion looks at the temperatures aloft and just finds where the freezing level must be from interpolation on those temperatures aloft! Simple!
So, with a single button-press, you get the clouds, freezing level, and icing risk all on-screen at once: Surely enough to avoid icing!

Now for those flights where you are NOT afraid of bad weather, you are instead annoyed by headwinds.
We often want to try different altitudes to duck headwinds, but that often puts us in turbulence!
So, now with Xavion, we show the winds aloft as arrows with speed indicators overlayed on the turbulence forecast map!
This lets us see the winds and turbulence all at once, easily! Now, just ONE button press to see both the WINDS AND turbulence, so you can make your altitude selection.

Cloud Tops
OK maybe everything with storms, icing, winds, and turbulence is just fine, but you just feel like getting out of the clouds anyway.
Just hit the could tops button to see how high you will have to go to escape the clouds to the top.

VFR/IFR Airports
And if you just want to see where you can go in a hurry for a VFR landing, then just hit this button and all the airports with weather reports will be shown in color (green for VFR, yellow for MVFR, red for IFR), with clouds as well so you can see what is VFR or clear at-a-glance. This is the sum of escape options available with a single button-press.

So, that is how the weather (including the new ADS-B weather!) is shown in Xavion, all with just five buttons right on the main map!
No more fumbling around for weather in flight: Everything is right there at a glance with one button-press for any given situation!

Oh yah and one more tiny thing: When you are NOT on the main PFD page, a screen-saver comes on after 5 minutes to prevent burn-in if you leave the phone alone for a long time to download all the charts and plates!
