The Federal Aviation Administration considers the iPad a Class 1 electronic device, which means it must be stowed during takeoff and landing -- even if you're a pilot. (Let's hope they don't need to take a peek at the manual during that time.)

The cost of the tablets will be offset by lower printing and distribution expenses and lower fuel consumption in aircraft since the tablet replaces several pounds of paper manuals, according to airline. Alaska also hopes the decrease in weight will help prevent back and muscle injuries caused by pilots lugging documents around.

Alaska is also looking into replacing paper navigation charts with electronic versions that would work on the iPad.

The Federal Aviation Administration approved the use of iPads instead of paper charts for on-duty pilots .
