Thoughts on the Construction of Test Flight Capabilities and Airspace Governance for the Low-altitude Industrial Chain

Low-altitude economy，as a national strategic emerging industry，covers links such as low-altitude manufacturing，flight activities and operation support. It has a long chain，wide radiation and a thriving new industry. At present，China’s general aviation flight hours are limited，the development cycle of new aircraft models is long，and it is difficult to obtain airworthiness certification for new aircraft such as electric vertical take-off and landing （eVTOL） aircraft，which leads to poor connection between upstream research and development and midstream test flights，restricting the development of downstream operations. At the same time，due to the prominent contradiction between the sharp increase in the number of aircraft and the limited control resources，the pressure on the safety of industry operations is increasing day by day. This article conducts thoughts on strengthening the construction of test flight capabilities and improving the airspace governance system to remove the bottlenecks in the industrial chain. It proposes to enhance the construction of test flight equipment and bases，promote the coordination among design，manufacturing and test flights，and shorten the airworthiness certification cycle. Establish an integrated airspace governance and hierarchical control mechanism for high，medium and low-altitude airspace，implement precise control over large high-speed aircraft，and adopt a filing system and post-responsibility management for small low-speed aircraft to balance airspace safety and operational efficiency.
