Airline groups split on in-flight mobile use, not enough data on interference


Skift Take

Retailers and the public pushing for in-flight mobile use dismiss pilots’ accounts of radio waves significantly interfering with systems. The FAA can’t afford to ignore such accounts and then deal with the blowback should any accidents that occur as a result.

The regional airliner was climbing past 9,000 feet when its compasses went haywire, leading pilots several miles off course until a flight attendant persuaded a passenger in row 9 to switch off an Apple Inc. iPhone. “The timing of the cellphone being turned off coincided with the moment where our heading problem was solved,” the unidentified co-pilot told NASA’s Aviation Safety Reporting System about the 2011 incident. The plane landed safely. Public figures from U.S. Senator Claire McCaskill to actor Alec Baldwin have bristled at what they say are excessive rules restricting use of tablets, smartphones, laptops and other devices during flights. More than a decade of pilot reports and scientific studies tell a different story. Government and airline reporting systems have logged dozens of cases in which passenger electronics were suspected of interfering with navigation, radios and other aviation equipment. The FAA in January appointed an advisory committee from the airline and technology industries to recommend whether or how to broaden electronics use in planes. The agency will consider the committee’s recommendations, which are expected in July, it said in a statement. Laboratory tests have shown some devices broadcast radio waves powerful enough to interfere with airline equipment, according to NASA, aircraft manufacturer Boeing Co. and the U.K.’s Civil Aviation Authority. Airlines Split Even Delta Air Lines Inc., which argued for relaxed rules, told the U.S. Federal Aviation Administration its pilots and mechanics reported 27 suspected incidents of passenger electronics causing aircraft malfunctions from 2010 to 2012. Atlanta-based Delta said it couldn’t verify there was interference in any of those cases. The airline industry has been divided. Delt
