Core Viewpoint - The article highlights the proactive measures taken by the East China Civil Aviation Administration and various airlines in response to extreme weather conditions, including snow and low temperatures, to ensure flight safety and passenger comfort during the winter season [1][2]. Group 1: Response to Weather Conditions - The East China Civil Aviation Administration organized a dispatch meeting to address the extreme weather, emphasizing the need for comprehensive understanding of flight scheduling, de-icing capabilities, and runway conditions [2]. - Various regulatory bodies, such as the Shandong and Jiangsu regulatory bureaus, conducted on-site inspections and remote supervision to ensure operational readiness and safety measures were in place [2][3]. - Airports in the East China region activated winter snow protection plans, ensuring that de-icing vehicles and materials were adequately prepared and that flight crews were trained in de-icing procedures [3][5]. Group 2: Operational Adjustments - Air traffic control departments increased the frequency of weather observations and forecasts to manage flight flow effectively, minimizing the risk of widespread delays [5]. - Continuous snow removal operations were conducted at airports, with personnel working around the clock to maintain runway and taxiway safety [5]. - Airports implemented various passenger services, including priority check-in for late arrivals and special assistance for vulnerable travelers, to mitigate the impact of weather on travel [5][6]. Group 3: Future Plans - The East China Civil Aviation Administration plans to implement a comprehensive management approach for winter operations, focusing on pre-snow inspections, ongoing supervision during snow events, and post-event reviews to enhance safety [6].

Core Viewpoint - The Civil Aviation Administration of China (CAAC) has issued a comprehensive plan for winter aviation operations in 2025, focusing on safety and efficiency in response to complex weather conditions and operational demands [1] Summary by Relevant Sections Operational Principles - The plan emphasizes three key operational principles: "safety as the foundation, precise assessment," "refined measures, dynamic response," and "collaborative linkage, closed-loop efficiency" [1] Risk Management and Coordination - A full-chain guarantee system is established, covering risk prevention, resource scheduling, and multi-party collaboration to enhance operational quality [1] Performance Targets - For the period from December 2025 to February 2026, the plan sets a target for the national average flight punctuality rate to be no less than 88%, with average takeoff delay times of less than 8 minutes [1] - Strict control standards are established for major airports and domestic passenger airlines regarding long delays, in-flight delays, and flight cancellations, aiming to prevent large-scale flight delays from causing passenger group incidents [1]

Core Viewpoint - The civil aviation industry in China is preparing for the upcoming summer thunderstorm season from June to August, which poses significant safety challenges and requires enhanced operational resilience and dynamic balance between supply and demand [1][4]. Group 1: Weather Challenges and Safety Measures - The summer season brings complex weather patterns, including concentrated and sudden rainfall, thunderstorms, hail, strong winds, and typhoons, which can significantly impact civil aviation operations [1]. - The industry must enhance its sensitivity and vigilance towards extreme weather risks, particularly thunderstorms and hail, by improving meteorological information collection, sharing, and forecasting [1][3]. - A comprehensive and timely approach to weather forecasting is essential, focusing on the specific needs of operational activities and enhancing collaboration between air traffic control, airlines, and meteorological departments [1][2]. Group 2: Dynamic Response and Coordination - The civil aviation sector must strengthen its dynamic monitoring, assessment, and adjustment capabilities to respond effectively to various uncertainties during operations [2]. - Emphasis is placed on the "Five Early" principles (early warning, early consultation, early decision-making, early handling, and early notification) to ensure rapid response in critical operational scenarios [2]. - A unified command and efficient operational system are necessary to manage flight delays and enhance passenger service levels during peak travel times [2][3]. Group 3: Proactive Risk Management - The industry is urged to adopt a proactive approach to risk management, focusing on the anticipation and prevention of potential weather-related disruptions [3]. - A thorough assessment of natural disaster risks during the flood season is critical, along with the development of targeted safety measures and preparedness plans [3]. - Effective management of air traffic flow and dynamic adjustments to flight schedules are essential to match capacity with market demand, especially during the upcoming summer travel season [3][4]. Group 4: Operational Goals - The recently released "2025 Thunderstorm Season Civil Aviation Operation Guarantee Overall Plan" sets a target for a flight regularity rate of no less than 70% during the June to August period [4]. - The industry must balance safety with operational flexibility, ensuring that safety remains the top priority while adapting to changing conditions [4].
