Xavion3.60 - App Store

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.

Continued use of GPS running in the background can dramatically decrease battery life.

Version History Support for all current Apple phone and pad sizes. 3.60 Oct 2 Now with the Emergency power-off hoops being OPTIONAL for DISPLAY.
Set in prefs window. 3.59 Sep 28 Support for IOS 27, large performance increase in terrain-rendering: You will notice the synthetic vision renders more fluidly. 3.58 Sep 23 Performance improvements! This version should run notably FASTER.
As well, you can enter custom FIXES. 3.57 Sep 18 Crash-fix for case where you lose all internet connections. 3.56 12/22/2025 Bug-fix for international terrain topography: We can now access terrain topography world-wide. 3.55 12/19/2025 Refinements:
Emergency approach banks of 10, 20, and 30 degrees are all tried, with preference for the SHALLOWER banks.
This is because shallow banks are easier to see and fly if you have enough altitude (and therefore TIME) to do them.

New low altitude fog added to give the terrain a bit more sense of depth.

Quicker tracking for the Sagetech Clarity ADSB receiver: The responsiveness to what the real airplane is doing should be quicker.
Bug fix:
Runway selection buttons are back, so you can touch an airport on the map, then hit a runway button there to get an emergency approach to that particular runway. 3.54 11/10/2025 Bug fix: The new higher-res elevation maps were not visible in some regions. That bug is now fixed, and the new high-res dems are now available between -60 and +70 degrees longitude. 3.53 11/11/2024 Removed un-needed warning when no terrain found in ocean areas. 3.52 11/04/2024 Faster emergency hoops-generation in the background so the selected airport for power-off approaches is updated every 10 seconds, even on older iPads and iPhones. 3.51 10/31/2024 Landing Options: A few more power-off options are now considered by the computer for short and long final approaches, and low and high-energy approaches, using just the near or far end of the runway as needed if you are going to be set up to come in short or run a bit long.

Detail Addition: Other traffic is now shown on the instrument approach plates as well as the main charts.

Bug fix: Removed un-need airspeed tick-mark. 3.50 10/15/2024 Now with 35% higher-resolution elevation maps in each direction... 82% more elevation data, thanks to a new compression algorithm.

Bug-fix in subscription-purchasing. 3.49 10/14/2024 No distracting error message in the UI if you are not able to connect to the net in intermittent internet conditions, as often happens at the airport or at low altitude. 3.48 09/26/2024 Fix to always allow a 30-day demo. 3.47 09/23/2024 Internal bug fixes in the weather-radar replay and weather-forecast display. 3.46 09/20/2024 UI tweak in the FMS to enter your flite plan, so a button-press is never missed. 3.45 09/16/2024 Minor UI fixes and some internal streamlining of the code to make it slightly faster and more robust. 3.44 09/13/2024 Bug-fix: The glide-range was showing a possible distance when taxiing: Now corrected. 3.43 05/21/2024 Slightly-better altitude control for instrument approaches: If you have many enroute fixes, Xavion will:
1: take you to the enroute altitude for that you enter into the FMS for each fix enroute,
2: take you to the enroute altitude for that you enter into the FMS for your destination airport,
3: delay descent for the instrument approach as long as possible to stay high as long as possible,
4: for each fix ON the instrument approach, descend you as quickly as possible to get into VMC.
Small UI tweaks to not hide any data behind the notch on phones, and some Apple permission tweaks. 3.42 05/20/2024 Xavion has always given red-alert terrain and obstacle warnings,
but now we give an advance yellow-alert warning as well, about 200 miles out,
if the HOOPS you are flying are going to intersect terrain or obstacles.

This gives you time to PLAN to enter higher enroute altitude with a yellow-alert,
and gives URGENT notice for maneuvering with a red-alert. 3.41 04/12/2024 More responsive FMS: We now get a quicker response, even on older pads and phones.
Slightly more conservative braking requirements after touch-down for all runways, since you will not have all your weight on the gear at the start of braking.
Hoops smoothed out a bit more with gentler bank-in and bank-out to allow more gradual pitching and rolling in flight. 3.40 04/10/2024 Small UI and hoop geometry tweaks.
Small internal RAM optimizations.
The emergency hoops now set you up with a bit more touch-down room than before to allow more gentle braking on touch-down, if the runway length allows it. 3.39 04/08/2024 Updated hoop profiles:
The INSTRUMENT approaches now have refined altitudes to help fly your altitudes on the approaches a bit more accurately.
The EMERGENCY approaches now give you more room for braking on the longer runways by bringing you down a little sooner, when runway length permits. 3.38 04/03/2024 Various user-interface tweaks:

When you select an approach in the FMS, you can change the altitude, fixes enroute, etc, without having to re-select the approach for the new route.
You can drag the mouse and the FMS waypoints more easily in the FMS page, dragging anywhere on the screen.
The hoops are slightly re-sized and re-spaced to be as easy as possible to fly.
The traffic icons are have a darker background so the numeric data on them really shows up. 3.37 04/02/2024 Now you can create custom FIXES as well as custom airports!
This is in the left-most NAV SETUP menu.
And remember to run Xavion on the same local network to send your custom fixes and airprots to your other devices! 3.36 03/20/2024
