Description

Technical Field

[0001] This invention belongs to the field of avionics technology and relates to a method for assisting decision-making in flight missions. Background Technology

[0002] The FAA predicts that global air passenger numbers will increase by 4% between 2020 and 2035. The China Aviation Industry Development Research Center projects that my country's air passenger turnover will grow at an average annual rate of 5.5% between 2020 and 2039, cargo and mail turnover at 7.0%, and general aviation turnover at approximately 13%-16%. This foresees that air traffic congestion and flight delays will become increasingly severe in the future. To maximize airspace utilization, mixed operations of military and civilian aircraft, as well as manned and unmanned aircraft, will be implemented within the same airspace. To improve air transport efficiency and save costs, a large number of unmanned cargo aircraft and unmanned express parcel delivery aircraft will emerge. It is foreseeable that future route optimization will be extremely challenging, and aircraft will need to face sudden conflicts and accidents and make rapid autonomous decisions, placing new demands on airborne systems.

[0003] Currently, civil aircraft operate pre-tactical flight plans. However, in actual operation, various factors cause deviations from the planned flight path, leading to airspace traffic conflicts. Simultaneously, unforeseen factors such as weather conditions can cause weather hazards that affect operations. Under the current air traffic control service system, the avoidance of short-to-medium-range traffic conflicts and medium-to-long-range hazardous weather is jointly the responsibility of the ground control service system and the airline's operations control department. While existing airborne systems and ground service systems possess or are about to possess the capability for real-time sharing of traffic and meteorological information, airborne systems currently lack the capability to support flight mission decision-making in response to traffic conflicts and hazardous weather. Summary of the Invention

[0004] The purpose of this invention is to provide a method for flight mission decision support. This method fully utilizes the interconnected, autonomous, and intelligent features of next-generation airborne avionics systems. Based on multi-source information such as traffic, weather, and terrain, it assesses in real time whether traffic conflicts or hazardous weather conditions exist. It autonomously plans a four-dimensional flight path using an intelligent planning algorithm, conducts flight mission simulations using mission simulation tools to assist pilot decision-making, and coordinates and confirms air-to-ground flight paths based on air-to-ground data links, ultimately coordinating with aircraft actuators to execute the confirmed path. This method effectively improves flight mission decision-making efficiency and flight autonomy, reduces pilot workload, and increases airspace utilization and operational efficiency. It effectively supports four-dimensional flight path-based operations, is easily engineering-implemented, and has significant practical application value for aircraft operations in the civil field, especially for supporting future single-pilot operation.
