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].
