I am a pilot and the IPAD would make an ideal EFB for the cockpit as it is very light and has a great battery life. There are some great programs that already work for PC tablets. How hard would it be to get these working on the IPAD so I don't have to develop every thing from scratch. For example I have performance software which works out how much runway I use to take off in the B777 that already works on a PC. What would it take to get this going on an IPAD. Thanks for your input.
