Solar-Powered GPS-WAAS, ADS-B And AHARS
Physically, the iLevil SW is a gray and black plastic box that's a bit larger than a pack of king-sized cigarettes, at 2.6x4.3x1 inches. One side has an antenna, and on the back you'll find a universal serial bus (USB) mini-port, on/off switch, charging light and a serial-in jack used when connecting it to other devices. The iLevil has an internal Li-Ion battery that the company rates at three to four hours, although on a bright day, the solar cells can extend that significantly—after a one- hour test flight on a sunny day, it still showed a 92% charge.
The iLevel SW supports applications on Apple's iOS (iPhone and iPad), Android and even Windows-based devices. It communicates with iOS and Android devices through a built-in Wi-Fi network. I tested it with two iOS applications: WingX Pro 7 from Hilton Software and Austin Meyer's Xavion.
WingX is an old friend—I first reviewed an early version (which ran on Windows-based Pocket PC hardware) some seven years ago. It has evolved into a complete electronic flight bag (EFB) app with preflight planning, moving map, electronic charts, a terrain profile view, ground proximity warning and airport information, including optional fuel pricing, among much more. As with most EFB apps, WingX requires a data subscription, and has many options for VFR and IFR pilots. Used with the iLevil, WingX also provides ADS-B weather, including NEXRAD radar images and field conditions, and traffic (with the limitations noted above). It also supports the iLevil's built-in AHARS with an effective attitude indicator or a simple synthetic vision display. One particularly nice feature of WingX on the iPad is a split-screen option, so you can have the attitude indicator or synthetic vision on half the display, while using the other half for a moving map or electronic chart.
It breaks new ground with two features weXavion, on the other hand, isn't a conventional EFB app, although it does provide a moving map and will display ADS-B NEXRAD images. It's the brainchild of Austin Meyer, an iconoclastic engineer who's the brains behind the X-Plane flight simulator. Xavion applies flight simulator logic to solving a problem we all hope never to face in flight: What happens if the engine quits? If that happens, Xavion automatically selects the nearest runway you're in a position to reach, and provides guidance to that runway using Highway in the Sky (HITS) fly-through boxes superimposed on a pretty impressive synthetic vision display. Xavion doesn't require a data subscription—$99 buys the app and includes a world-wide database derived from X-Plane.
