Abstract
This article studies on the analysis of safety characteristics of flight situation in complex low-altitude airspace with Agent-based simulation. Several aircraft behavior models are proposed taking...
Highlights
Low-altitude airspace is an important part of the national airspace system, and the main flight area of various kinds of general aircraft, which is of tremendous economic and social values.[1]
In conflict detection and resolution (CDR) area, various CDR algorithms were clustered;[2,3,4,5,6] two lowaltitude flight conflict resolution models based on speed adjustment and heading adjustment were proposed, and the models were verified with controller simulator;[7] a low-altitude flight conflict resolution algorithm and related system architecture were proposed based on the concept of see-and-avoid and in reference to traffic collision avoidance system (TCAS) and visual flight rule;[8] a convective weather avoidance model (CWAM) aiming at possible convective weather problems based on the meteorological information database was College of Civil Aviation, Nanjing University of Aeronautics and Astronautics, Nanjing, China
Advances in Mechanical Engineering developed;[9] the inter-coordination problem was studied among aircraft groups within certain airspace from the perspective of integer linear programming and a 0–1 linear programming model was built;[10] agent technology was used to study the modeling and simulation of complex low-altitude flight activities, and the characteristics of complex low-altitude mixed flight situation were explored by developing a complex low-altitude flight simulation platform taking account of general aircraft Agent and low-altitude environment Agent;[11] an adaptive control modeling and simulation method was proposed for general aviation based on optimal control theory.[12,13]
Summary
Low-altitude airspace is an important part of the national airspace system, and the main flight area of various kinds of general aircraft, which is of tremendous economic and social values.[1]. In order to objectively and accurately characterize the complex low-altitude flight situation safety, the following indicators are defined: Flight volume n: total number of general aircrafts in low-altitude airspace at a given time. Average speed-change DV : average speed-change volume of general aircraft with speed adjustment in a low-altitude airspace at a given time (or time period) at time t, and conflictit0Àt1 is the total number of conflicts that occurs to aircraft i in time period t0 À t1.
