The U.S. Federal Aviation Administration (FAA) has finally relaxed its restrictions on the use of personal electronics devices (PED) such as iPhones and iPads on commercial flights. Going forward, the FAA will allow airlines to expand use of personal electronics during nearly all phases of flight, and is immediately providing the airlines with implementation guidance.
Although the FAA has finally determined that smartphones and tablets have a minimal impact on the airplane's electronic systems, pilots of course are barred from using gadgets for personal reasons at any time during aircraft operations.
