[The Magical Mischief Tour]

We've already had similar technology onboard our Gulfstream for a while now.

CMA-1100 Electronic Flight Bags (EFB's) I've been using these for a few years now and love'em. They do performance calculations, display checklists, moving map, weather applications, video display and wireless communications.

Thanks for the picture. That is way cool. Is that what you fly? Are you on the high end of private aviation? So what are they talking about here? Something for the lower price range? Something a weekend pilot could use?

A "killer app" is defined as an application (or more than one competing application) that, all by itself, justifies the purchase of the device. Electric pencil, VisiCalc, Lotus 1-2-3, Pagemaker, Final Cut all were worth the price of the systems they ran on.

Jeppesen looks like a killer app for the iPad (in aviation; other fields have their own). The iPad hardware is about 1/5 the cost of the dedicated EFB systems I could find in a quick Google, and they're a lot more versatile when you exit the cockpit.

All you need is one of these:

Performance calculations? Did Gulfstream quit putting perf computers on their airplanes?
