Xavion, by Austin Meyer.
Xavion is MY answer to the question: How helpful can I make an iPad in the cockpit?
In flight, Xavion constantly imagines engine-failed glides to every runway in gliding range. For each of these glides, Xavion scores the chance of a successful power-off landing based on runway length, runway width, headwind, tailwind, or crosswind on that runway, the weather around the airport, and a number of other factors. Then, once Xavion has estimated the chance of a successful landing at EVERY runway within gliding range, it shows you the approach that it believes is best as 3-D hoops that you simply glide through to make it to the runway! The hoops are set up at the glide ratio for your airplane, so you can stay in them with power off!
This, finally, gives you guidance after an engine failure that is based on energy-management all the way down, where the computer does the work for you… all you need to do is fly through the hoops.
As well, Xavion gets ADS-B weather (if you have a Sagetech or iLevil receiver) and shows it on a moving map, and provides weather for all airports that report it. As well, Xavion gets METARS and winds aloft from the internet if you have a WIFI or cell signal before or during flight!
Also, Xavion checks your weight and balance, medical and BFR currency, 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 length from your current location on the runway is too little for a safe take-off.
Also, Xavion estimates time and fuel burn at all different altitudes to any destination you want to go to, and shows you 3-D “highway in the sky” hoops to get there.
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 by a Seattle Avionics Chart Data subscription for $149.00/year, or access your EXISTING Seattle Avionics Chart Data subscription freely.
This is the most user-friendly, powerful App that I can imagine, and I love flying with it.
