Core Viewpoint - The third Civil Aviation Science and Technology Innovation Achievement Exhibition showcased various "air taxis," highlighting the importance of airworthiness certification for commercial passenger operations [1][2]. Group 1: Air Taxi Development - "Air taxis" are described as futuristic vehicles capable of vertical takeoff and landing, with a cruising speed of 200 km/h, enabling autonomous flight [2]. - The M1 eVTOL can reduce travel time from the National Stadium to Beijing Daxing International Airport from nearly 2 hours to 30 minutes, with ticket prices comparable to taxi fares [2]. Group 2: Airworthiness Certification Process - The airworthiness certification process is crucial for ensuring aviation safety, involving the review and management of hundreds of subsystems throughout the lifecycle of civil aircraft [4]. - The certification process is complex, with examples such as the C909 regional aircraft taking 11 years and the C919 large passenger aircraft taking 12 years to complete their respective certifications [4][5]. Group 3: Technological Advancements in Certification - The rapid development of the drone and eVTOL manufacturing industries has led to a significant increase in airworthiness certification demands [6]. - Advanced information technologies, such as remote manufacturing compliance inspection tools, are being utilized to enhance the efficiency of the airworthiness certification process [7].

Core Points - China's self-developed electric aircraft RX4E has successfully obtained the type certificate from the Civil Aviation Administration of China (CAAC), becoming the world's first electric aircraft to achieve this certification [1] - The Chinese civil aviation sector is actively participating in international aviation standards development, transitioning from a "rule follower" to a "standard setter" role [2][5] - The CAAC has been increasingly recognized in international aviation circles, particularly in the field of electric aircraft certification, due to its growing experience and capabilities [3][4] Group 1: Electric Aircraft Certification - The RX4E is the first of 23 electric aircraft to receive a type certificate, marking a significant milestone in China's aviation innovation [1] - The CAAC has contributed to the development of international standards for electric aircraft, showcasing China's advancements in this area [3][4] - The establishment of the CAAC's certification center has led to a greater accumulation of expertise and recognition in international forums [2][4] Group 2: International Collaboration - China has been actively involved in the International Civil Aviation Organization (ICAO) and has contributed to the formulation of electric aircraft certification standards [3][5] - The CAAC has established bilateral airworthiness relationships with 10 countries and signed airworthiness memorandums with 21 countries, enhancing international cooperation [7] - The ongoing collaboration aims to strengthen global aviation safety standards and integrate new technologies into the aviation sector [6][7]
