Background With the rapid development of novel aircrafts such as unmanned aerial vehicles, electric vertical take-off and landing aircrafts (eVTOL), airspace, particularly low-altitude airspace, is in front of unprecedented traffic pressure. Traditional air traffic management relies primarily on fixed airlines, predetermined flight plans, and voice communications, as well as rule books in the form of text and diagrams, which suffer from the following inherent drawbacks: 1. The traditional airspace rules are static and fixed, and rapid and dynamic rule updating and loading are difficult to carry out according to real-time airspace states, weather changes or sudden events, so that the airspace structure is difficult to rotate from static; 2. The method is complex and error-prone to execute, wherein an aircraft or a driver needs to manually read complex text and chart rules (such as graphics, tables and written limits), and flight control is performed by relying on indirect instructions, so that the efficiency is low, and high man-machine understanding difference and safety challenges exist; 3. Safety challenges are that, for non-collaborative or high automation aircraft, the lack of direct, digital instructions that allow the aircraft to "see, fly, etc. is of limited perception and avoidance capabilities. Existing unmanned aerial vehicle management systems (such as UTM), while attempting to integrate some rules, lack unified, three-dimensional, dynamic rule injection and expression capabilities, and have difficulty converting abstract flight restrictions into stereoscopic digital instructions that can be directly executed by the aircraft.
