I've often complained about the Army's Electronic Data Manager (EDM), a digital "kneeboard" the size of a brick. Running on Windows XP and featuring a 133 mHz processor, the device is heavy, slow, counter-intuitive, and must stay tethered to the aircraft to receive GPS data.
I've often argued that an iPad could outperform the EDM, which is based on technology some ten years old. That's why I was pleased to learn that Jeppesen, the world's leading manufacturer of aeronautical charts, has created a flight information application which includes approach diagrams, maps, departure procedures, and airfield diagrams. And unlike those that rely on paper charts, there's no need to purchase new maps and approach diagrams every few weeks.
I'm going to give the free trial a test over the next week or so. More to follow.
