Using an iPad on a plane during takeoff is one of the biggest sins in the galaxy. Just ask Alec Baldwin. There hasn’t been much proof that it’s bad, but no one wants to test fate. The Federal Avaiation Administration is finally starting to relax on their electronics rules though.
American Airlines just became the first commercial carrier to get FAA approval to kit their pilots’ flight bags with iPads, and they get to use them in “all phases of flight.” I bet the pilots are stoked that they get play Angry Birds In Space during takeoff.
