A senior civil aviation management official said that more reports have surfaced about the radio interference during the flights as planes and routes increase. The radio problems are also occurring as more airports are built.
An industry expert said that the small radio stations who illegally increase their signals are adding to the interference. The Western regions in China experience fewer radio interference cases compared to the other parts of the country.
An official from the Civil aviation administration of China on the condition of anonymity said, “Radio interference can be dangerous because it could mean a temporary or longerconnection outage between a plane and traffic management on the ground”. Zhao Yifei, a professor studying air traffic management at the Civil Aviation University of China said that the interference comes due to the radio station signals mainly.
In a recent case which occurred on July 12, 2012 when the captain of a plane flying from the south western city of Chengdu in Sichuan province to Wuhan had heard a pop song when he was talking to the air traffic management staff on the ground. Even on May 23, many of the flights in Guangzhou Baiyun airport were delayed due to severe interference of the radio stations.
