[iPhone God App] It was found using the FlightPlan actually

FlightPlan is a native iPhone/iPod Touch application for both professional and hobbyist pilots. At its core, FlightPlan functions as an aviation calculator by simplifying many common calculations typically performed with an E6B slide rule computer. FlightPlan makes quick work of your number crunching, and is even used by CFIs to quickly check their student's flight and leg calculations (see Leg Calculator feature).

FlightPlan has evolved beyond the core functionality. It now offers many advanced features, including Weight and Balance calculators (with live plot!) for both airplanes and helicopters, live METARs and TAFs, airport data, flex weight calculator, windstar calculator, etc.

FlightPlan will continue to evolve as I incorporate more user requested features. My goal is to make FlightPlan as "all inclusive" as possible, so please let me know if there are features you are looking for that FlightPlan does not already offer.

The development of FlightPlan is greatly influenced by your comments and feedback so drop by the forum or shoot me an email and say hello!

Please visit the dedicated website for lots more screenshots and product walkthroughs.
