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.

All USA VFR and IFR charts and plates are included with base subscription.

Great augmented situational awareness

Xavion is great once you configure and really get everything dialed in. It changes a lot each release even minor ones so you really have to keep on top of what changes occur so you know how to use it properly.

I have practiced “engine out” procedures with it several times and it really does bring you to a runway but practice with it because it sometimes doesn’t bring you where you would see the runway miles before getting there if the airport area has trees or is hidden.

I am considering dedicating an iPad mini to just xavion for emergency field location only. For me I am not yet willing to use it as a full efb. Excellent tool in the cockpit

Developer Response ,

Starting with 2.48, the maps are included with the base subscription at no extra charge. So there is no extra sign in and no extra charge. EVERYTHING is included with the base app subscription. I did this so people would not keep having to sign in again within the App, or buy other plans in addition to the App itself. There's no additional log-in because the charts are now included with the base app subscription.

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.

Fantastic SA with the additional the Flight Director

With the addition of the Flight Director capability I have truly fallen in love with this app. I have it connected to my Stratux box and it is AMAZING how accurate it is to my actual altitude and airspeed. I’m still dialing in on how best to use the flight director capabilities but having it up and running all time and then able to hit the emergency button if something happens to give you guidance to the nearest airport is incredible. Also having additional 3D reference to approaches and the missed procedure is unprecedented in an iPad app. Looking forward to future improvements as the app is always getting better.
