Summary of the Conference Call on Low Altitude Air Traffic Management Systems and Drone Industry Industry Overview - The conference focuses on the low altitude air traffic management (ATM) systems and the drone industry, highlighting the challenges and opportunities within these sectors [2][3][4]. Key Points and Arguments - **Delayed Development of General Aviation ATM**: The construction of general aviation ATM is lagging, heavily relying on foreign practices, particularly in autonomous drone operations, which primarily use high-frequency voice calls for confirmation, lacking complex traffic management and real-time control, making it unsuitable for drones [2][4]. - **Challenges in Drone and Manned Aircraft Integration**: The integration of drones with manned aircraft faces challenges, as newly established institutions often provide similar functions, mainly focusing on information or coordination services, lacking true regulatory services. The drone system's tiered structure is also incomplete, necessitating the integration of Flight Operations Services (FOS) and Unmanned Aircraft System (USS) [2][6]. - **Classification of Drones by Weight**: Drones are classified by weight, with heavy-lift drones (over 100 kg) categorized as medium or above, showing significant potential in infrastructure and emergency rescue applications, offering better cost-effectiveness compared to traditional methods, especially in power line inspections and bridge lifting [2][8]. - **Market Segmentation**: The drone market is divided into consumer and industrial segments. The consumer market is saturated, dominated by DJI, while the industrial market, particularly for heavy-lift drones, still has substantial growth potential with diverse application scenarios [2][9]. - **Technical Challenges in Airspace Management**: Drone airspace management faces technical challenges, including the need for isolation analysis between manned and unmanned aircraft. Current systems rely on 4G/5G public networks for data transmission, lacking high-frequency communication technologies, necessitating significant investment to build a complete framework [2][10]. - **Importance of ADS-B Technology**: ADS-B technology is widely used in manned aircraft but less so in drones. A similar data link mechanism has been defined for small drones, but no clear solutions exist for larger drones. The installation of ADS-B hardware is mandatory to receive broadcasts from manned aircraft to formulate avoidance strategies [2][12]. Additional Important Insights - **Regulatory and Management Gaps**: The drone industry faces regulatory challenges due to the late development of the air traffic management system, with a lack of effective management links and unified standards for communication between ground operators and drones [2][11]. - **Investment and Infrastructure Needs**: The construction of air traffic management systems is complex and requires substantial investment. Key networks include communication, navigation, and surveillance systems, which need careful planning and investment coordination among various government levels [2][13][14]. - **Recent Developments in Low Altitude Airspace Management**: Some regions have begun refining low altitude airspace management, delegating authority to local governments for areas below 300 meters, while a unified approach for higher altitudes remains undefined [2][15]. - **Core Companies in Air Traffic Management**: Key players in the air traffic management system construction include companies like Lais Information, Nairui Radar, and Weihai Guangtai, which play crucial roles in developing the low altitude monitoring and communication networks [2][20]. This summary encapsulates the critical aspects of the conference call, providing insights into the current state and future directions of the low altitude air traffic management systems and the drone industry.
