Core Viewpoint - The successful operation of the fifth runway at Guangzhou Baiyun International Airport marks a significant milestone in China's aviation sector, establishing it as the first airport in the country to operate five runways and two control towers simultaneously [1][2]. Group 1: Runway and Tower Operations - The fifth runway, located 1530 meters east of the second runway, is 3600 meters long and 45 meters wide, capable of accommodating large E-class aircraft [1]. - The Civil Aviation Administration of China (CAAC) and the Air Traffic Management Bureau guided the successful launch of the fifth runway, overcoming challenges such as heavy workload and adverse weather conditions [1]. - The simultaneous operation of five runways allows for more diverse takeoff and landing patterns, presenting new challenges for air traffic control [1][2]. Group 2: Air Traffic Management Innovations - The Civil Aviation Central South Air Traffic Management Bureau has designed various approach and departure combinations to reduce air traffic conflicts and enhance flight efficiency [2]. - A comprehensive evaluation of the flight procedures for the fifth runway was conducted, ensuring safety and operational feasibility [2]. - The introduction of five new sectors, including two departure and arrival sectors, aims to accommodate peak traffic scenarios effectively [2]. Group 3: Technological Advancements - The implementation of runway status lights and an Advanced Surface Movement Guidance and Control System (A-SMGCS) ensures that the new runway and tower maintain industry-leading technical standards [3]. - The introduction of the first S-band dual-polarization phased array weather radar in national civil aviation enhances the ability to monitor complex weather conditions, significantly improving operational efficiency [3]. - The development of real-time rainfall monitoring and precipitation forecasting modules provides more efficient meteorological services for the operation of the five runways [3]. Group 4: Future Developments - The Civil Aviation Central South Air Traffic Management Bureau plans to continue optimizing the operational schemes for the five runways and deepen multi-disciplinary collaboration to support the construction of a world-class airport cluster in the Guangdong-Hong Kong-Macao Greater Bay Area [3].
