Last week the FAA updated its rules about when you can use your electronic devices during flight. Instead of turning off your eReader or mobile device during take-off and landing, you can now keep reading or listening to your book. Make sure to turn your wireless devices to airplane mode.
Passengers will eventually be able to read e-books, play games, and watch videos on their devices during all phases of flight, with very limited exceptions. Electronic items, books and magazines, must be held or put in the seat back pocket during the actual takeoff and landing roll. Cell phones should be in airplane mode or with cellular service disabled — i.e., no signal bars displayed — and cannot be used for voice communications based on FCC regulations that prohibit any airborne calls using cell phones.
