"United Airlines tests iPad for 'paperless flight deck'":

The iPad weighs about 1.5 pounds, [Captain Joe] Burns said, while the flight bag containing paper copies of charts and handbooks weighs about 40 pounds. United estimates the savings will be about 326,000 gallons of jet fuel a year and 16 million sheets of paper...

What pilots won't be able to do with the iPads -- just like passengers can't -- is turn on the devices during takeoffs and landings...

United pilots also won't be able to play mobile app games like "Angry Birds," sort through their e-mail or watch movies.
