This app is only available on the App Store for iOS devices.


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 in Version 1.85

"Emer Circling" approaches now get you into any airport in a pinch, with lateral AND VERTICAL guidance for power-off approaches:
In the NAV page, enter any airport ID. "Emer Circling" buttons will appear for each runway on the field.
Hit one, and an approach will be generated to that runway (if no terrain or obstacles interfere with it from your present position).
This approach is generated at your power-off glide steepness, to let you fly to the hoops power-off to drop in.
This is a little bit of a 'slam-dunk' approach, since it is power-off at nominal glide descent angle, but that is probably the best option to get down quickly with maximum terrain clearance.

New close-in "short-game" approaches. Now, Xavion also considers close-in approaches where you throw flaps and gear down in a hurry to decelerate quickly.
Historically Xavion has always been oriented towards the possibility of power-loss when far from runways where computer guidance is most needed, but now we handle the close-in cases better as well, which may be useful in dark or low-visibility situations
where a runway may be close, but you still depend on synthetic-vision to see your options.

Slightly tighter hoop spacing for a little more detail on those close-in approaches, and slightly more-frequent airport checking to adapt to rapidly-changing situations in those close-in approaches where things happen faster.

New tighter UI. Leaves more room for the PFD, map, and landscape modes on tall, thin phones like the iPhone-7.

Customer Reviews

Life-saving tool

Excellent situation awareness, terrain avoidance and emergency landing guidance. Xavion works on an iPhone as well as it does on an iPad. I mount it next to my undersized cockpit console, and have complete panel back up in case of electrical failure. I use earbuds underneath my headset for audible terrain avoidance alerts. When I get ADS-B, I will also enjoy traffic alerts. Xavion works seamlessly with X-Plane for flight planning and proficiency simulation.
With Seattle Avionics subscriptions (additional) do you have moving me up display on VFR Sectional, IFR Enroute charts and Approach Plates.
All I would ask in addition to these features is a one touch transition between approach plates and Highway-in-the-sky guidance to the threshold.

Another great update!

I have flown with this app for several years. It gives you the piece of mind you need to always know your path to the best suitable airport. Amazingly put together. Runs great when populated with your aircrafts individual data points. Developer is always providing great updates and always improving the app.

It just works

As a new pilot I found this app adds to my sense of situational awareness on many levels- from an accurate weight & balance envelope to confidence in knowing where to land upon a power failure.

The weight & balance envelope feature is fantastic for my 2 place trainer where useful payload weight capacity is on the light side and balance tends aft heavy.

I have tested the engine out feature, and yes the app will guide you via hoops right down to the nearest airport runway in an engine failure.

I use Xavion running FlyQ on an i-pad mini on a RAM mount with a Bose A20 headset, a bluetooth Garmin GLO WAAS GPS and a Uvionix Ping ADSB-in for weather & traffic.

I am looking forward to using Xavion in the future with the levil BOM with AHRS.
