ã€World Wide Web Reporter Lin Di】 On September 18, at the regular press conference of the Civil Aviation Administration of China, Zhu Tao, deputy director of the Civil Aviation Department’s Flight Standards Division, disclosed that “the operation approval certification for the operation of large aircraft public air transport carriers†The fifth revised release will be implemented starting in October 2017. This revision broadened the regulations on the management of on-board portable electronic devices, allowing airlines to assess the impact of the main body on portable electronic devices and formulate corresponding management and usage policies. Figure: Future planes will be able to use mobile phones Zhu Tao said that airlines can determine what kind of portable electronic equipment to use on the aircraft based on the results of the assessment. The original government is forbidden. Now the government has given this power to airlines for evaluation. Second, the CAAC Flying Standards Division has formulated a corresponding method for review and evaluation to accept airline applications. "I believe that in the near future, you will see Chinese airlines allow the use of portable electronic devices on airplanes," said Zhu Tao. According to Li Yuan, a civil aviation communications expert, the radio used by mobile phones belongs to the same band as the radio used by the aircraft and may cause harmonic interference. This is why the United States once banned the use of mobile phones on airplanes. However, to date, there have been no cases where the use of mobile phones has caused aircraft communications and navigation interference, and no clear experiment can prove the harm of interference. Li Chen, vice president and chief innovation officer of IAIO-NARDO Aeronautical Aeronautics Technology, told Global World that with the development of aviation technology, the level of aircraft manufacturing, especially the advancement of avionics and communications equipment, some of the old technical regulations have lagged behind. The government functional departments have simplified their powers to meet the needs of market development and have given the industry companies more service options. This measure can effectively help aviation companies develop their own service standards. Once promoted, passengers can achieve a more personalized aviation entertainment experience. As of now, there are over 40 jurisdictions in the world that allow the use of mobile communication services on aircraft. Some airlines also provide wireless network services on aircraft: Etihad’s Etihad Airways is the world’s airline that provides on-board internet connectivity throughout the entire flight; Lufthansa also takes the lead in the international community to allow passengers to use mobile phones at an altitude of 10,000 meters; The United States Federal Aviation Administration announced on October 31, 2013 that American Airlines can safely expand the use of portable electronic devices other than voice communications at all stages of flight.
