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 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, 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. As well, Xavion 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 a Seattle Avionics Chart Data subscription for $149.00/year, or access your existing Seattle Avionics Chart Data subscription.

(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 2.06

New for 2.06: Quicker synthetic vision response in turns, to make it easier to fly the hoops!
This is surprisingly important: A smooth, rapid synthetic vision system is critical to being able to fly these hoops at night or in IFR conditions!

Stratus-3 AHRS lock-out in unusual attitudes: The Stratus-3 AHRS system fails above about 65 degrees or about 2.5 G’s.
When this failure occurs, Xavion automatically takes over attitude display, which I have tested to 3G’s and 120 degrees of bank.

Memory optimizations: The RAM requirement is now a little bit lower.
This matters a lot, because Apple has a way of shutting down Apps when the memory usage gets high, so memory efficiency is critical!

Also new for Xavion 2: Airspace and airways in the Xavion gliding map, and FMS capabilities.
Now with ADS-B integration: You now enter your TAIL NUMBER in the aircraft preferences.
Do this where you enter whether the plane is pressurized or has retractable gear.
Then, Xavion will filter your plane out from the traffic display to avoid warning of a collision with yourself!
This is a common occurrence with all portable ADS-B receivers, and solved by simply entering your own tail number into Xavion.

Also recently added:

We now have AIRWAYS on the Xavion gliding-map, with an FMS that allows you to fully navigate them.
Here is how it works:
Go to the PLAN tab and enter your destination and any number of waypoints along the way, including airways!
Enter your desired cruising altitude.
Then, in flight, just fly through the hoops in 3D to get to your destination, traversing fixes and airways along the way!
As well, if ATC ever clears you direct to a fix along your route, just enter direct to that fix and hit the SHORTCUT button, and Xavion will update your Highway-In-The-Sky hoops direct to that destination, with all of your flight plan after that point remaining intact!
And, while doing this, Xavion shows you the airways and your gliding range at the same time.
This is literally lets you navigate the busy north-east corridor, IFR, following Highway-In-The-Sky hoops, with the FMS on your phone, while always knowing your power-off options for landing.
It is a new level of professionalism and safety.
Also new is AIRSPACE display on the Xavion gliding-map!
This is useful for watching out for airspace during routine flight operations, while still keeping an eye on your glide options on a continuous basis, putting you way ahead of everyone else in the sky in situational awareness, since you are seeing both airspace for LEGAL operations, and gliding options for SAFE operations, all at once.

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.

I never fly without this app running and mounted on my panel - this is huge safety insurance. Try it - you AND your passengers will feel a new level of relaxation!
NOTE: I had a self-inflicted mess up in my craft configuration entries and emailed Austin for help. He spent considerable time and several back and forth emails to find and explain my problem! That is a HUGE benefit in a program as detailed and important as this one can be if you'll let it! Wonderful support!

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.
