Flight program design system for performance-based navigation, verification platform and verification method

Abstract

The invention discloses a flight program design system for performance-based navigation (PBN), a verification platform and a verification method, belonging to the field of aerial navigation. The program design system is based on an AIXM (Aeronautical Information Exchange Model) core database; a program protection region can be automatically drawn, an obstacle is evaluated, and a chart is generated; and thus, functions such as seamless connection and the like of the PBN program protection region and the conventional flight program protection region can be realized. According to the system, the chart can be automatically generated according to data finished by the flight program design, customized edition and modification can also be realized according to requirement, and program design and publishing are finished at one time. By using the flight program design system, the verification platform and the verification method, the PBN program can be directly added in a navigation database of the verification platform, and the navigation database can be edited and modified in a verification process. In addition, a visual scene database is increased; the defects and the disadvantages of the program design can be directly discovered according to geomorphology in a visual scene when the PBN flight program is verified; and the program is further modified perfectly.

Description

technical field [0001] The invention belongs to the field of aviation navigation, and in particular relates to a performance-based navigation flight program design system, a verification platform and a verification method. Background technique [0002] The rapid development of China's economy has promoted the rapid growth of the civil aviation industry. Since 1978, the annual growth rate of the total turnover of China's civil aviation transportation has been 18%, which is about twice the growth rate of GCP in the same period. In 2000, the total turnover of China's civil aviation transportation ranked ninth in the world, fifth in 2003, third in 2004, and second in the world in 2005. In recent years, it has maintained its second position and has become a major civil aviation country. Although China's civil aviation transportation system as a whole maintains rapid and steady development, the rapid development of China's civil aviation also faces many challenges, mainly includi...

Problems solved by technology

However, there is currently no commercial platform at home and abroad for a platform specially used for program verification

Therefore, the current program verification uses a full-motion simulator for pilot training. One of the main problems in program verification is the long verification cycle time, because the program code is produced by FMS navigation database company, and the production of FMS navigation database The period is 28 days. After the verification, if there is a problem with the program and needs to be modified, it needs to wait until the next production cycle to modify. A PBN program design usually needs to be modified more than two or three times. Each modification needs to wait 28 days to modify the navigation database. The more times, the more cycles are consumed, and the time is too long

At the same time, there is also the difficulty of using a full-motion simulator to verify the high cost

[0032] At the same time, the versions of simulators used for PBN program verification in foreign countries are very different and span a long time. Not all simulators have the simulator visual database of the verified airport. However, some of them cannot be installed. When the verification is performed on the simulator installed to verify the airport vision, once the EGWPS terrain database gives an alarm during the verification process, the problem can be found directly according to the airport vision, and the program can be modified, but the lack of vision When the data simulator has a terrain warning, it is necessary to conduct in-depth research and discussion on the problem, and conduct multiple verification flights to determine the cause
