Computer virtual environment simulation and check system for performance based navigation flight program

Abstract

The invention provides a computer virtual environment simulation and check system for a performance based navigation (PBN) flight program, and belongs to the field of civil aviation navigation. The system comprises a data layer, a model layer, a display layer and an application layer, wherein the data layer is used for processing flight program data, topographic data and barrier data; the model layer provides a navigation system, a dynamic system and an enhanced ground proximity warning system of an airplane for virtual verification of the flight program; the display layer is used for providing two-dimensional display and three-dimensional visual systems for a user during virtual verification; and the application layer provides man-machine interaction and flight program verification applications for the user. The system realizes the verification of the PBN flight program in a virtual environment generated by a computer, is simple and convenient, shortens verification cycle, reduces costs and improves working efficiency; and a result can evaluate flight program design, guide actual flight verification and meet PBN flight program verification demands.

Description

technical field [0001] The invention belongs to the field of civil aviation navigation, in particular to a performance-based navigation (PBN) flight program computer virtual environment simulation verification system. Background technique [0002] There are many airports in our country, especially special airports, whose operating conditions are limited. In addition, the construction of infrastructure and ground navigation stations in the western region of my country is not perfect, and the signal coverage of navigation stations and surveillance radars is not complete. With the rapid economic development of the western region, the construction of civil aviation infrastructure in the western region is facing severe challenges. Traditional ground-based navigation facilities in these airports and regions are difficult to meet operational needs, and new navigation methods are needed to organize operations. Therefore, performance-based navigation (PBN) technology will have great...
