US aviation regulators began considering the greater use of laptops, tablets and e-readers on board, while still ensuring they don’t compromise flight safety. Many passengers are unhappy about current restrictions. While some fear their devices will disrupt navigation or radio signals, others consider the risks remote. The report by an industry-government committee recommends allowing tablets and e-readers to remain on at altitudes below 10,000 feet on newer planes that are designed to resist electronic interference. Larger devices such as laptops or DVD players should still be stowed for takeoff and landing so they don’t pose a physical hazard. Cell phone calls weren’t considered, and would still be banned during flights. Current commercial airplanes models, made by Boeing Co , Airbus, Embraer SA and Bombardier Inc, are designed to resist interference from portable electronic devices. Older aircraft may need further checks to ensure safety.
