近年来，随着便携式电子设备特别是移动电话的日益普及，在民用航空器上使用移动电话和其他电子设备的现象也日渐增多，对飞行安全已构成威胁。大量证据表明在飞机上使用移动电话等便携式电子设备会产生电磁干扰，造成飞机导航设备、自动驾驶仪系统失灵进而严重危及航空安全。 In recent years, with the increasing popularity of portable electronic devices, especially mobile phones, the increasing use of mobile phones and other electronic devices on civil aircraft has posed a threat to flight safety. There is ample evidence that the use of portable electronic devices such as mobile phones on aircraft can generate electromagnetic interference, resulting in the failure of aircraft navigation equipment and autopilot systems, thereby seriously endangering aviation safety.
