In flight, Xavion constantly imagines engine-failed glides to every runway in gliding range, and then shows you the safest-possible route as a Highway-In-The-Sky to take to an airport 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. Xavion also has instrument approaches in 3-D for the United States, so you can simply select any approach and then fly through the hoops to fly it!

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, 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 portable receiver, and displays it, including the new icing, turbulence, and lightning products. Xavion also gets METARS and winds aloft from the internet if you have a WIFI or cell signal to help you plan before a flight!

Also, Xavion checks your weight and balance, 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 runway length from your current location is marginal for a safe take-off.

Also, Xavion estimates time and fuel burn at all different altitudes to any destination, showing you the time and fuel burn required for each altitude enroute, so you can pick the best altitude.

Xavion, and Xavion alone in the sky, gives engine-failure guidance and wake-turbulence avoidance.

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 buy USA Sectional Charts, Low and High Enroute Charts, and Approach Plates for $149.00/year.

(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 2.35

Bug fix: Crash-on-launch bug fixed, which could happen if you have added custom-airports.

Other recent improvements: For power-off airport selection, Xavion now gives a bit of preference towards selecting airports that are CLOSER, even if farther airports are still technically within glide range. This gives you the ability to descend quickly if you want (as desired for pressurized airplanes that have lost pressure, a guaranteed result of losing power in a single-engine pressurized plane!)
This will also make it a bit more likely that you can CIRCLE down rather than glide TO a destination, allowing you a bit more flexibility in your descent.

Small UI Improvements and Bug fixes:

The resolution used to go to poor settings when rotating between Portrait and Landscape on some older devices.
This is now fixed, and Xavion is confirmed to run all the way back to the iPhone 8!

The main menus used to disappear sometimes when Xavion was in HUD mode. This is now fixed.

The touch-zone for the numeric entry is now displayed as larger, to make it easier to see where to touch.

The due-date for your medical exam was previously confused if you were within a dew days of turning 40 on the day of your medical, but this is now fixed!

There’s a lot to like about this app. Although it’s cumbersome to get set up and really requires a subscription to Seattle avionics maps and charts to be fully functional, I really love the situational awareness of the safe glide function. Written from an engineers perspective, the app takes some getting used to but once you figure it out it really works well.

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.

Xavion Top Rated

I have used Xavion for 3 years now and I believe it’s one of the best aviation apps to give you a sense of security while in a single engine airplane flying day or night as it continuously looks for airports you could glide to based on your aircrafts glide characteristics. All you have to do is fly the highway-in-the-sky hoops! I have it turned on with every flight on a separate iPad. In addition, it can be used with X-Plane to practice engine out emergencies as well as in the actual aircraft. Regards, Don
