Xavion 1.45 is here, with the following new stuff:

We now have new hoop symbols! They are SOLID in the LOWER half, DASHED in UPPER half!

This may SEEM like a minor change, but it is actually rather huge: You can now tell, at-a-glance, exactly where the CENTER of the hoops are!

You just fly along right at the TOP of the solid part!

That will have you right in the center of the hoops perfectly, keeping your ideal energy level all the way to the green gate, which is the point at which you start your round-out for landing.

This really clarifies the meaning of the hoops, and I have found that I can fly within ONE PERCENT of the center of the hoops just by observing where the dashed part starts, and flying right between the sold and dashed part of the hoops.

We now use the iPhone6 barometric pressure sensor for altitude display if you have an iPhone6 or iPad with pressure sensor, and are NOT set up as a pressurized airplane in CONFIG:OPTION screen.

I have found from flight-test that the iPhone6 pressure sensor is more accurate in altitude than the GPS!

Be sure to enter your local barometric pressure in PREFLIGHT:WEATHER INPUT if you do not have an ADS-B receiver or a cell connection, which in Xavion load the barometric pressure for you!

So, here is the current altitude hierarchy:

1: If you have an iLevil with pitot-static system, then Xavion will use that pressure, and auto-set the barometric pressure for you based on the ADS-B reports or WIFI or cell-tower weather (!)

2: Otherwise, if you have an iPhone6, and NOT set up as a pressurized airplane in the CONFIG screens, then Xavion will use that pressure, and auto-set the barometric pressure for you based on the ADS-B reports or WIFI or cell-tower weather (!)

3: Otherwise, Xavion will estimate altitude based on GPS.

See the PREFLIGHT:WEATHER tab to see what sort of weather you are getting, and note the label on the altimeter to see if it is BARO or GPS altitude.

We now have a whole new obstacle-rendering philosophy:

We now have no more OPTION to plot ALL the obstacles: Instead we just ALWAYS plot the ones that COULD ACTUALLY MATTER!

Obstacles are now shown even if beyond gliding range, which is good so Xavion can warn you if you get too close to them, no matter how low your gliding range!

You see, the idea is that Xavion needs to warn you about impending OBSTACLES… regardless of what your GLIDING RANGE is.

And it needs to ALWAYS do this… not fail to do so because you might have turned the obstacle rendering OFF for some reason.

How many accidents have we seen because the user turned OFF a warning system for some reason… only to have it absent when needed?

So, to avoid this, the obstacle rendering and warning system is ALWAYS on… but ONLY drawing the obstacles that might be a threat, so you do not get a lot of annoying clutter of un-needed obstacles on the display!

Another idea is that I want LESS buttons and knobs and switches.

Instead, I want Xavion to automatically show you what you need to see, so you have a minimum of things to set or worry about.

So, the name of the game for 1.46 is further UI and other safety enhancements as I continue to very rapidly improve the App as I fly it constantly in a wide range of both simulated and real aircraft, and you get back to me with desired improvements or other area of confusion, and I work constantly to eliminate any possibly-confusing element of the App. I will only be happy when Xavion is like the helpful AIs in the science fiction movies: Infinitely knowledgeable, but transparently easy to access.


Now on with the show:

From the creator of X-Plane comes Xavion, the iPad app that helps you fly safer.

See the AOPA report here.

Xavion is always prepared for an engine-out in your plane, and will guide you to the safest nearby airport at the touch of a button.Your safety-conscious copilot.

Xavion is always imagining the worst that could happen, so you don’t have to.

If you have an engine out, Xavion will plot an easy-to-fly course to a nearby runway.

Xavion knows about your plane’s glide characteristics and the nearby terrain, so it guides you to the safest nearby runway—not just the closest.

Xavion's synthetic vision display, showing the terrain profile ahead of the airplaneSynthetic vision, without the cost of a traditional glass cockpit.

Your situational awareness is about to get an upgrade.

Xavion shows you the surrounding terrain with startling clarity, so you always know what’s around you.

Xavion provides backup versions of all your primary flight instrumentsNever worry about an instrument failure again.

Xavion provides an iPad-powered backup of your primary flight instruments. If one goes out, simply switch on Xavion and continue on your way.

When connected to an external GPS unit, Xavion’s instrument readings can rival the ones built into your panel!

Flying a highway-in-the-sky path to a destination using XavionHighway-in-the-sky navigation, at your fingertips.

With point-to-point navigation from Xavion, just enter your destination and desired altitude. Xavion provides easy-to-fly “hoops” to take you there.

Plus, Xavion will estimate your ETA and fuel burn at different altitudes, so you can choose the fastest or the most efficient path.

What our customers say

I just caught up with the latest on Xavion and am blown away. [The safety features] included are breathtaking in scope. And I’m dumbfounded that you are making all this available in an iOS app. It’s astounding!

Your product is revolutionary in so many ways. It’s the most innovative thing I’ve seen in a very long time. It may very well be the most significant advance in aviation safety since the parachute. I believe that ultimately it will save many lives, not to mention aircraft.

Xavion will be with me any time I am ever PIC again.
