Hugh Pickens writes writes: "AFP reports that Federal Communications Commission chairman Julius Genachowski is calling for an easing of the ban on using mobile phones and other electronic devices on airplanes during takeoff and landing saying devices such as smartphones "empower people" and can boost economic productivity. "I write to urge the FAA to enable greater use of tablets, e-readers and other portable electronic devices during flight, consistent with public safety," the FCC chief said in the letter to FAA Administrator Michael Huerta. "They empower people to stay informed and connected with friends and family, and they enable both large and small businesses to be more productive and efficient, helping drive economic growth and boost US competitiveness." The ban is in place based on the assumption that devices could interfere with an airplane's navigation equipment. But a number of news stories have questioned the validity of this claim, and many point out that some people forget to turn off their devices during flights. The FCC studied the question several years ago but found insufficient evidence to support lifting the ban at the time. But not everyone has been forced to put their gadgets away. Earlier this year the FAA approved iPads instead of paper flight manuals in the cockpit for pilots, but the agency still refuses to allow passengers to read Kindles and iPads during takeoff and landing."
