Xavion vs Levil Aviation
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Xavion
This app provides critical in-flight guidance for engine failures, calculating safe glide routes to airports. It also offers 3D instrument approaches, tracks aircraft and their wake turbulence, and displays real-time weather data. Additionally, it assists with pre-flight planning, weight and balance calculations, and takeoff performance analysis.
- Engine-out glide path calculation
- 3D instrument approaches
- ADS-B aircraft and wake turbulence tracking
- Real-time ADS-B weather display
- Weight and balance calculations
- Takeoff distance estimation
- Enroute time and fuel burn estimation

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