Flight Quality Analysis and Evaluation System

This system is based on a general PC hardware platform, and will obtain the FDR (Flight Data Recorder) or QAR (Quick Access Recorder) data (files) recorded during the flight according to the decoding equipment, in the form of continuous three-dimensional animation, The attitude of the aircraft and the information on various instruments and other related information during the flight are displayed on the display output device of the computer. The expanded system can also synchronize the digital CVR (cabin sound recorder) information with dynamic images. play.

Function:

1. Simulation data processing function: analyze the data obtained from the data analysis software, determine the flight stage to be reproduced, extract the parameters required for the simulation, process the abnormal data so that it does not affect the simulation effect, calculate and correct the aircraft's Positioning information (including rough positioning - latitude and longitude level and precise positioning - meter level) and altitude information and other parameters, and finally generate the required simulation data (table, library).

2. Display flight attitude function: In a simulation scene, the aircraft attitude is displayed in the form of observing the aircraft from the outside viewpoint of the aircraft. The simulation scene includes the airport runway, the main runway lights, the main runway marking lines, the main buildings of the airport, and the vicinity of the airport. Mountain peaks and horizons or skylines that affect the clearance, while the simulation scene can simulate the luminosity of day and night; for aircraft, it can also display changes in aircraft landing gear, flaps, etc.; in addition, it can simulate the scene observed from the driver's point of view .

3. Display instrument information function: Considering the limitations of the display screen, data source and system operation capability, it is impossible for the simulation software to display all aircraft instruments, so no matter what type of aircraft, PFD, ND and ECAM are used. Instrument panel display, or switch display; other important parameters such as time, overload, throttle position and other information are also displayed.

4. Display related information function: related information includes three-dimensional track information; airport information, etc.; aeronautical chart information of the entire flight segment, such as Jeppesen chart.

5. The control function of the simulation process: set a group of playback control buttons in the simulation software, which can play normally, fast forward, pause, fast reverse, skip to the previous/next event playback starting point: you can switch the viewpoint observation position during the simulation process , point-of-view viewing modes, dashboards, and other information displays.

6. Auxiliary analysis function: It is used to analyze the pilot's manipulation of the aircraft during the flight, which can mark the start and end points of events above a certain level or give prompts for the occurrence of events; the synchronous representation of the graph and the selected data parameter curve during the simulation process; Add the normal track to compare the overrun track, and even the "normal" flight process and the actual flight process are superimposed and played for comparison.
