Larry Greenemeier defends the unpopular FAA regulation. Two of his arguments:
2. It’s less risky to let passengers use portable electronics (with the exception of cell phones) at cruising altitudes above 3,000 meters* because the flight crew would have more time to diagnose and address any possible interference than they would during takeoff or landing.
3. Because passengers bring such a variety of portable electronics onboard in so many different states of function or disrepair, the FAA can’t assure that none of them will interfere with flight instrumentation. The agency thus tells carriers to prohibit their use completely during critical phases of flight.
