Abstract: An airspace network optimization method based on a flight normality target is capable of comprehensively considering spatial and temporal distribution of national air traffic demands, a service capability of an airspace network and a capacity increase limit of each airspace unit according to the flight normality optimization target on the basis of carrying out pre-analysis on a flight operation efficiency under a current airspace service capability, to position a key problem airspace and generate a capacity expansion suggestion of the related airspace; and aims at improving the flight operation efficiency by expanding the airspace service capability, and providing technical support for a user to carry out analysis and optimization work of national airspace network problems at a strategic level.

Abstract: A time-space conversion method of flight sequencing information aims to solve a problem that a flight sequencing suggestion generated by an arrival management system has poor effect in practical application due to abstract characteristics, comprising: generating a sequencing time and a delay suggestion of a flight in each key point in a terminal area and each runway by using a flight sequencing technology; predicting a flight status of the flight according to a current position and 4D trajectory information of the flight, and filtering a delay-consumed flight segment, and on that basis, generating a flight segment delay allocation strategy with reference to an aircraft performance and sequencing information, and obtaining a flight segment delay allocation result; and generating a visual spatial position reference target according to the flight segment delay allocation result and an operation deviation limit.

Abstract: A flight schedule optimization method based on a flight normality target is capable of carrying out pre-analysis on flight operation efficiency of a current flight schedule based on a national air traffic control service capability, and on this basis, generating a corresponding flight schedule adjustment suggestion according to a flight normality optimization target, which aims to provide a technical support means for carrying out flight schedule rationality analysis and optimization in strategic air traffic flow management.
