Engineering and aviation experts are saying that electronic devices can interfere with an airplane’s controls. While the experts also say that the signals emitted by electronic devices don’t cause a problem every time (and not even close to the majority of the time), they still have the potential to cause trouble in the cockpit during takeoff and landing.

In fact, a recent report by the International Air Transport Association cites 75 cases where electronic interference may have caused problems with a plane’s autopilot, autothrust, and landing gear, even navigation and communications systems.
