Description

Technical Field

[0001] This invention relates to the field of flight simulator cockpit simulation technology, specifically to a multi-eVTOL flight simulator cockpit synchronous simulation and collaborative operation training system. Background Technology

[0002] With the rapid development of urban air mobility (UAM) and electric vertical takeoff and landing (eVTOL) flight simulators, the number of flight simulators and the complexity of their missions are constantly increasing. In future air mobility systems, it will become the norm for multiple flight simulators to perform missions collaboratively, such as air taxi platooning, urban emergency rescue, and air logistics delivery. These missions place higher demands on pilots' collaborative operational capabilities.

[0003] Existing flight simulator systems are mainly designed for single-flight simulated cockpit operation training. The specific method is to first set a single flight mission, such as a specific route flight or take-off and landing training. The pilot operates in the simulated cockpit according to the preset program. The system collects operation data through built-in sensors, such as joystick displacement and throttle control, and at the same time simulates the flight environment and feeds it back to the pilot, such as turbulence and changes in visibility.

[0004] The aforementioned technical solutions lack support for collaborative operation among multiple flight simulator cockpits. Therefore, there are still many technical bottlenecks in aspects such as state synchronization, collaborative task simulation, and dynamic environment response among flight simulator cockpits. For example, the flight states among multiple flight simulator cockpits cannot be synchronized with high precision, which can easily lead to inconsistent behavior in the simulation environment. There is a lack of training mechanisms for pilot collaborative operation, which cannot effectively simulate complex scenarios such as formation flight, collaborative obstacle avoidance, and task allocation. There is a lack of real-time recording and analysis of pilot operation behavior, which cannot provide effective feedback for training results. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figure 1 As shown, in one embodiment, a multi-eVTOL flight simulator cockpit synchronous simulation and cooperative operation training system is provided, the operation training system comprising:

[0056] A flight simulation unit, comprising multiple identical flight simulation cockpits, is used for interaction between the pilot and the simulation system;

[0057] The central processing and simulation unit includes a synchronous simulation server and a scene rendering server; the synchronous simulation server is used to receive control information data from all flight simulator cockpits, run flight dynamics models, and output flight status information data of all flight simulator cockpits in the simulation environment; the scene rendering server generates virtual scene image data.

[0058] The data management and command unit includes a data recording and analysis server and a command terminal; the data recording and analysis server records and analyzes flight status information data and pilot operation data in real time; the command terminal is used to monitor the training process and inject fault scenarios.

[0059] Network communication equipment, specifically network switches, is used to connect the flight simulation unit, central processing and simulation unit, and data management and command unit into a local area network.

[0060] Through the above technical solution, this embodiment uses multiple identical flight simulator cockpits for interaction between each pilot and the simulation system; the synchronous simulation server in the central processing and simulation unit receives control information data from all flight simulator cockpits, runs flight dynamics models, and outputs flight status information data of all flight simulator cockpits in the simulation environment; the scene rendering server generates virtual scene image data; the data recording and analysis server in the data management and command unit records and analyzes flight status information data and pilot operation data in real time; the command terminal monitors the training process and injects fault scenarios; and the flight simulation unit, central processing and simulation unit, and data management and command unit are connected into a local area network through network communication equipment. This achieves highly consistent synchronous simulation of multiple flight simulator cockpits in a unified virtual environment, and enables collaborative operation training, data recording, and evaluation for multiple pilots. It effectively solves the technical problem that existing single-aircraft simulators cannot perform multi-aircraft collaborative training, and is particularly suitable for pilot training of new aircraft such as eVTOL.

[0061] In one embodiment of the present invention, the flight simulator cockpit includes a cockpit shell; the flight simulator cockpit further includes:

[0062] Display devices, including a main display screen and an auxiliary touch screen, are used to present flight visuals and interactive control interfaces;

[0063] Control devices, including a side stick, throttle, and rudder pedals, are used to control the flight simulator cockpit;

[0064] The data communication interface is used to collect operational information data of the pilot controlling the flight simulator cockpit and transmit it to the cockpit's built-in computer.

[0065] The cockpit has an onboard computer that processes the control information data input by the pilot and transmits it to the synchronous simulation server.

[0066] Through the above technical solution, this embodiment presents the flight scene and interactive control interface through a main display screen and an auxiliary touch screen. The multi-screen design ensures a clear presentation of the flight scene and interactive control interface, improving the pilot's ease of operation and situational awareness. Then, the pilot operates the flight simulator cockpit using control devices such as the side stick, throttle, and rudder pedals, simulating a real cockpit and enhancing the realism of training. Next, the pilot's operation information data for operating the flight simulator cockpit is collected through a data communication interface and transmitted to the cockpit's built-in computer. Finally, the cockpit's built-in computer processes the control information data input by the pilot and transmits it to the synchronous simulation server. This ensures accurate data transmission and achieves efficient data processing and synchronous simulation, providing pilots with a realistic, accurate, and efficient training environment, effectively improving training quality and effectiveness.

[0067] As one embodiment of the present invention, the operation training system works as follows:

[0068] S1: Determine the collaborative training objectives and tasks for this operation training through the command terminal;

[0069] Specifically, the command terminal can select the collaborative training target task for this operation training either manually or randomly.

[0070] S2: Obtain the target task information data of the collaborative training target task through the data recording and analysis server; the target task information data includes several key synchronization time points, flight task information data of each flight simulator cockpit, and standard information data of pilot flight operation procedures;

[0071] Specifically, flight mission information data may include initial specified coordinates, specified movement trajectory, key time and key attitude angle data of key points on the specified trajectory; pilot flight operation procedure standard information data includes key time points and standard operation parameters for each standard operation action; synchronization key time points can be set by staff according to the specified movement trajectory of the collaborative training objective task, and the number of synchronization key time points can be adjusted according to the task complexity of the collaborative training objective task; the higher the task complexity, the more synchronization key time points; the lower the task complexity, the fewer synchronization key time points; the method of obtaining task complexity is existing technology and will not be detailed here; after collecting and optimizing the operation action data obtained by a sufficient number of highly skilled and experienced pilots when performing the collaborative training objective task, it is used as pilot flight operation procedure standard information data; this process is existing technology and will not be detailed here.

[0072] It should be noted that, for ease of understanding, the standard information data of flight operation procedures are illustrated with examples; for example, the standard information data of any flight operation procedure is: Action 1: Push the throttle, parameter is the percentage of position moved to 80%, time is the 20th second; Action 2: Depress the rudder pedal, parameter is the depth of 10 mm, time is the 40th second; This means that the rudder pedal is depressed to a depth of 10 mm at the 40th second after the start of flight.

[0073] S3: Transmit the flight mission information data of each flight simulator cockpit of the collaborative training objective task to the display devices and synchronous simulation server of each flight simulator cockpit; transmit the synchronous key time points and standard information data of the pilot's flight operation procedures of the collaborative training objective task to the synchronous simulation server;

[0074] S4: Each pilot under test operates the flight simulator cockpit through the control equipment, and collects the operation information data of the pilot under test operating the flight simulator cockpit through the data communication interface and transmits it to the cockpit built-in computer and synchronous simulation server.

[0075] S5: The synchronous simulation server uses the control information data of the flight simulator cockpit and runs the flight dynamics model to output the flight status information data of the flight simulator cockpit in the simulation environment.

[0076] Specifically, flight status information data may include the flight trajectory coordinates of the actual flight simulator cockpit, the timestamps of each trajectory coordinate, and the actual attitude angle data of the flight simulator cockpit (attitude angles include pitch angle, roll angle, and yaw angle).

[0077] S6: By comparing and analyzing the flight status information data, pilot operation data, flight mission information data and standard information data of pilot flight operation procedures of the pilot under test between each synchronous key time point, the flight standard level of each pilot between each synchronous key time point is obtained.

[0078] Specifically, pilot operation data includes the name, time, and operation parameters of each operation;

[0079] Through the above technical solution, this embodiment first determines the collaborative training objective task for this operation training through the command terminal, either manually or randomly, increasing the flexibility and diversity of the training. Manual selection allows for specialized training on specific mission scenarios based on actual needs, enabling pilots to deeply master the operational skills and collaborative key points of specific missions. Random selection simulates the unpredictability of missions in real flight, improving pilots' ability to cope with emergencies and their adaptability, effectively enhancing the practicality of the training. The data recording and analysis server stores a large amount of target mission information data, providing solid data support for subsequent training. The setting of synchronous key time points ensures clear time control during the training process, facilitating accurate evaluation and analysis of pilots' operations at different stages. Flight mission information from each flight simulator cockpit is also included. Data and standard information on pilot flight operation procedures provide pilots with clear operational guidance and standard references, helping them to standardize their operations and improve the standardization and accuracy of training. The synchronous simulation server runs flight dynamics models and outputs flight status information data, making the training environment closer to real flight scenarios. This allows pilots to train in a highly simulated environment and better adapt to various situations in actual flight. Finally, by comparing and analyzing various data, flight standard levels are obtained, enabling a comprehensive evaluation of pilots' training performance at each synchronous key point from multiple dimensions. The resulting flight standard levels accurately reflect the changes in each pilot's skill level throughout the entire collaborative training process, providing a clear direction for subsequent training improvements and enhancements. This helps improve pilots' collaborative combat capabilities and overall flight level, ensuring the safe and successful completion of flight missions.

[0080] As one embodiment of the present invention, the process of obtaining the flight standard level between each synchronization key time point of each pilot under test is as follows:

[0081] S11: Set each flight simulator cockpit to its initial designated coordinates;

[0082] Specifically, the synchronous simulation server can determine the initial designated coordinates of each flight simulator cockpit, facilitating subsequent comparison between the actual flight trajectory and the designated movement trajectory of each flight simulator cockpit.

[0083] S12: After the collaborative training objective task begins, acquire the actual flight trajectory, the number of actual flight reaching the designated trajectory key points, the actual time, and the actual attitude angle data of two adjacent synchronous key time points in each flight simulator cockpit.

[0084] Specifically, the methods for obtaining the actual flight trajectory, the number of actual flight reaching the designated trajectory key points, the actual time, and the actual attitude angle data of two adjacent synchronization key time points in each flight simulator cockpit are all existing technologies and will not be described in detail here.

[0085] S13: Based on the actual flight trajectory of two adjacent synchronous key time points in each flight simulator cockpit, the number of actual flight reaching the designated trajectory key points, the actual time, the actual attitude angle data, the name, time, and operation parameters of each operation action;

[0086] S14: By analyzing the actual flight trajectory, the number of times the actual flight reaches the designated trajectory key points, the actual time, and the actual attitude angle data of the two adjacent synchronization key time points of each flight simulator cockpit, as well as the key time and key attitude angle data of the designated movement trajectory and the designated trajectory key points, the mission synchronization quality index is obtained.

[0087] Specifically, the mission synchronization quality index is used to evaluate the actual completion quality of collaborative training objectives in each flight simulator cockpit.

[0088] S15: By analyzing the names, times, and operating parameters of the operational actions of each pilot under test in each flight simulator cockpit, as well as the key time points and standard operating parameters of each standard operational action, an operational standard index is obtained.

[0089] Specifically, the Operational Standard Index is used to assess the operational deviations of the pilots under test and professional pilots in each flight simulator cockpit, so as to facilitate corresponding guidance to the pilots under test.

[0090] S16: Based on the analysis of the mission synchronization quality index and the operation standard index, the flight standard index between each synchronization key time point of each pilot under test is obtained.

[0091] Specifically, the flight standard index between each synchronous key time point of each pilot under test is used to comprehensively evaluate the actual completion quality of the collaborative training objective task between each synchronous key time point and the operational deviation between the pilot under test and the professional pilot, thereby reflecting the flight standard status of the pilot under test between each synchronous key time point.

[0092] S17: Obtain the flight standard level of each pilot under test between each synchronization key time point based on the flight standard index between each synchronization key time point of each pilot under test.

[0093] Specifically, the flight standard level of each pilot under test at each synchronous key time point can intuitively reflect the performance of each pilot under test at each synchronous key time point, which facilitates effective and targeted guidance to each pilot under test.

[0094] Through the above technical solution, this embodiment first acquires the actual flight trajectory, the number of times the actual flight reaches the designated trajectory key points, the actual time, and the actual attitude angle data of each flight simulator cockpit at two adjacent synchronization key time points, and compares and analyzes these data with the designated movement trajectory, the key time of the designated trajectory key points, and the key attitude angle data to derive a mission synchronization quality index. This index can comprehensively evaluate the actual completion quality of each flight simulator cockpit in the collaborative training objective mission from multiple dimensions such as the accuracy of the flight trajectory, the timeliness of the arrival of key points, and the precision of attitude angle control. For example, in simulating a complex formation flight mission, if the actual flight trajectory of a certain flight simulator cockpit is different from the designated trajectory, the synchronization quality index is obtained. Significant trajectory deviations, time delays in reaching critical points, and unstable attitude angle control result in a low mission synchronization quality index, reflecting deficiencies in mission completion quality within the cockpit. This provides a clear basis for subsequent targeted training. Then, the names, times, and parameters of the pilots' actions in each flight simulator cockpit are compared and analyzed with the critical time points and standard parameters of each standard action to obtain an operational standard index. This index accurately quantifies the differences in operation between the pilots under test and professional pilots. Whether it's deviations in timing or inaccuracies in parameters, the operational standard index clearly reflects these differences. For example, in simulated takeoff, if the pilot under test pulls up... If the control stick timing is ahead of or behind the standard time, and the pull-up angle parameters do not conform to the standard parameters, the operation standard index will reflect these specific problems, helping instructors to gain a deeper understanding of the pilot's operating habits and skill shortcomings. Then, based on the mission synchronization quality index and the operation standard index, an analysis is conducted to obtain the flight standard index for each pilot at each key synchronization time point. This index organically combines the actual completion quality of the flight mission with the pilot's operational deviations, scientifically reflecting the pilot's overall flight standard performance at each key synchronization time point. For example, even if a pilot's operation standard index is low, a low mission synchronization quality index indicates that their overall performance in the coordinated mission... The pilot's performance still needs improvement; conversely, if the mission synchronization quality index is high but the operational standard index is high, it indicates that the pilot needs to strengthen their operational standardization. The flight standard index provides a scientific basis for comprehensively and objectively evaluating the pilot's training level. The flight standard level between each synchronization key time point is obtained based on the flight standard index between each pilot under test. The flight standard level reflects the performance of each pilot under test between each synchronization key time point in a visual way, such as different levels like excellent, good, qualified, and unqualified. Instructors can gain a deeper understanding of each pilot's specific performance at different synchronization key time points, thereby providing effective and targeted guidance to each pilot.For example, if a pilot's flight standard is low at a critical synchronization point, and the main problem lies in mission synchronization quality, the instructor can focus on strengthening the pilot's training in coordinated flight skills and team communication and coordination. If the problem mainly stems from operational deviations, the instructor can emphasize guiding the pilot to standardize operational actions and improve operational precision. This targeted guidance can greatly improve training efficiency, enabling pilots to more quickly enhance their coordinated combat capabilities and overall flight performance, ensuring the safe and successful completion of flight missions.

[0095] As one embodiment of the present invention, in step S14, formula one is used:

[0096] ;

[0097] Calculate the mission synchronization quality index F between the (n-1)th (n≥2)th and nth synchronization critical time points in any flight simulator cockpit. n ;

[0098] Among them, G nc The maximum overlap between the actual flight trajectory and the designated movement trajectory of the flight simulator cockpit between the (n-1)th and nth synchronization key time points is given by M; M is the number of key points of the designated trajectory within the (n-1)th and nth synchronization key time points traversed by the actual flight trajectory between the (n-1)th and nth synchronization key time points, where m∈M; Q n The specified number of trajectory key points between the (n-1)th and nth synchronization key time points; t m The duration of the first characteristic of the actual flight trajectory of the flight simulator cockpit passing through the m-th designated trajectory key point between the (n-1)th and nth synchronization key time points; t m0 α is the duration of the first specified feature of the specified trajectory key point m between the (n-1)th and nth synchronization key time points on the specified trajectory; m α is the actual pitch angle of the m-th designated trajectory key point on the actual flight path between the (n-1)-th and n-th synchronization key time points; m0 β is the specified pitch angle for the m-th specified trajectory key point on the specified trajectory between the (n-1)-th and n-th synchronization key time points; m β is the actual roll angle at the m-th designated trajectory key point between the (n-1)-th and n-th synchronization key time points on the actual flight trajectory; m0 π is the specified roll angle for the m-th specified trajectory key point on the specified trajectory between the (n-1)-th and n-th synchronization key time points; m π is the actual yaw angle at the m-th designated trajectory key point between the (n-1)-th and n-th synchronization key time points on the actual flight trajectory; m0The specified yaw angle for passing through the m-th specified trajectory key point on the specified movement trajectory;

[0099] In the formula, γ1 and γ2 are preset weighting coefficients, used to represent... and The weight of the mission synchronization quality index at the (n-1)th and nth critical synchronization time points is considered significant. A larger value indicates greater importance in calculating the mission synchronization quality index, meaning it is more crucial for measuring the synchronization between the pilot's actual flight trajectory and the designated movement trajectory. It directly reflects the actual flight synchronization time difference, therefore a large weighting coefficient is assigned to it, and A smaller weighting coefficient is set based on γ1+γ2=1, where γ1>γ2. The specific values ​​of γ1 and γ2 can be set by the staff based on the above relationship, such as γ1=0.6 and γ2=0.4. No restrictions are imposed here.

[0100] In the formula, C1 and C2 are preset adjustment constants used to adjust the... and These heterogeneous data are transformed to similar scales so that they can be fused within the same analytical framework; the specific values ​​of C1 and C2 can be set by the staff themselves based on the above relationship, such as setting C1=1 and C2=0.2, without any restrictions here;

[0101] Formula 1 Explanation; G nc The maximum overlap between the actual flight trajectory and the designated movement trajectory of the flight simulator cockpit between the (n-1)th and nth synchronization key time points; The first ratio is the ratio of the number of designated trajectory key points within the (n-1)th and nth synchronization key time points to the total number of designated trajectory key points between the (n-1)th and nth synchronization key time points. A larger maximum overlap indicates a larger first ratio, signifying a closer alignment between the actual flight trajectory of the flight simulator and the designated movement trajectory between the (n-1)th and nth synchronization key time points. Therefore, it indicates that the pilot's actual flight trajectory is more compliant with regulations. At this point, the mission synchronization quality index F between the (n-1)th and nth synchronization key time points of the flight simulator is considered. n The larger; The first characteristic duration and the average time difference between the first specified characteristic duration of each designated trajectory key point on the actual flight trajectory between the (n-1)th and nth synchronous key time points of the flight simulator cockpit; The average attitude angle deviation of the actual flight trajectory of the flight simulator cockpit between the (n-1)th and nth synchronization key time points is the average attitude angle deviation value of each designated trajectory key point. The larger the average time difference, the larger the average attitude angle deviation value, indicating that the pilot under test has a greater time deviation and attitude deviation when arriving at each synchronization key time point, and therefore a greater impact on the synchronization of each flight simulator cockpit. At this time, the mission synchronization quality index F between the (n-1)th and nth synchronization key time points of the flight simulator cockpit is... n The smaller;

[0102] Through the above technical solution, this embodiment comprehensively and accurately evaluates the mission synchronization quality of the flight simulator cockpit between adjacent key synchronization time points by taking into account key factors such as the maximum overlap between the actual flight trajectory and the specified movement trajectory, the ratio of the number of key points passed through the specified trajectory, the average time difference, and the average attitude angle deviation value through Formula 1.

[0103] It should be noted that the first characteristic duration refers to the time from the start of flight on the actual flight trajectory of the flight simulator cockpit to the time from the arrival at the m-th designated trajectory key point between the (n-1)th and nth synchronization key time points; the first designated characteristic duration refers to the time from the start of flight on the designated movement trajectory to the arrival at the m-th designated trajectory key point between the (n-1)th and nth synchronization key time points.

[0104] As one embodiment of the present invention, in step S15, formula two is used:

[0105] ;

[0106] Calculate the operational standard index P between the (n-1)th and nth synchronization critical time points in the flight simulator cockpit. n ;

[0107] Where R is the number of standard operating actions between the (n-1)th and nth synchronization critical time points, r∈R; t r The second characteristic duration of the actual execution of the r-th standard operating action between the (n-1)-th and n-th synchronization critical time points; t r0 The second specified characteristic duration of the standard operating action between the (n-1)th and nth synchronization key time points; p r p represents the actual execution parameter value of the r-th standard operation action between the (n-1)-th and n-th synchronization critical time points; r0 Specify the execution parameter value for the r-th standard operation action between the (n-1)-th and n-th synchronization critical time points; ω 1rω represents the weighting coefficient of the time deviation of the r-th standard operating action in the calculation of the operating standard index. A larger value indicates a greater impact of the time deviation of that standard operating action on the operating standard index. The specific value of the weighting coefficient can be set by the staff according to the importance of different operating actions. 2r ω represents the weighting coefficient of the parameter deviation of the r-th standard operating action in the calculation of the operating standard index. A larger value indicates a greater impact of the parameter deviation of that standard operating action on the overall operating standard index. The specific value of the weighting coefficient can be set by the operator according to the importance of different operating actions, and it usually satisfies ω. 1r +ω 2r =1 (for each r);

[0108] Explanation of Formula 2: The ratio of the second characteristic duration and the first specified characteristic duration of the r-th standard operating action between the (n-1)-th and n-th synchronization key time points; The first deviation ratio is the ratio of the actual execution parameter value to the specified execution parameter value of the r-th standard operating action between the (n-1)-th and n-th synchronization key time points. The larger the first deviation ratio and the second deviation ratio, the greater the difference between the pilot's operating action and the standard operating action. Therefore, the operating standard index P between the (n-1)-th and n-th synchronization key time points in the flight simulator is... n The smaller;

[0109] Through the above technical solution, this embodiment incorporates the first deviation ratio of the second characteristic duration of each standard operation action between the (n-1)th and nth synchronous key time points and the second deviation ratio of the actual execution parameter value and the specified execution parameter value into the calculation using Formula 2. This clearly determines the difference between the pilot's operation action and the standard operation. The larger the first and second deviation ratios are, the smaller the operation standard index is, which can intuitively reflect the standardization of operation, provide a reliable basis for flight training and evaluation, and help improve the pilot's operation skills and the efficiency of flight simulation training.

[0110] As one embodiment of the present invention, in step S16, formula three is used:

[0111] ;

[0112] Calculate the flight standard index B between the (n-1)th and nth synchronization key time points in the flight simulator cockpit. n ;

[0113] Formula 3 explains that the operational standard index P between the (n-1)th and nth synchronization critical time points in the flight simulator cockpit... nThe larger the value, the smaller the difference between the pilot's actions and the standard actions, and the more standardized the pilot's actions are; when the mission synchronization quality index F between the (n-1)th and nth key synchronization time points in the flight simulator cockpit is... n The larger the value, the better the flight quality and synchronization of the flight simulator cockpit used by the pilot under test, and therefore the better the pilot's flying skills. Thus, the flight standard index B between the (n-1)th and nth synchronization critical time points of the flight simulator cockpit... n The larger the value, the greater the operational standard index P between the (n-1)th and nth synchronization critical time points in the flight simulator cockpit. n The smaller the value, the greater the difference between the pilot's actions and the standard actions, and the less standardized the pilot's actions are; when the mission synchronization quality index F between the (n-1)th and nth key synchronization time points in the flight simulator cockpit... n The smaller the value, the worse the flight quality and synchronization of the flight simulator cockpit used by the pilot under test, and therefore the worse the pilot's flying skills. Thus, the flight standard index B between the (n-1)th and nth synchronization critical time points of the flight simulator cockpit... n The smaller;

[0114] Through the above technical solution, this embodiment combines the operational standard index and the mission synchronization quality index using Formula 3. This not only comprehensively considers the standardization of the pilot's operational actions as well as the flight quality and synchronization of the flight simulator cockpit, providing a holistic evaluation of the pilot's flight skills and making the assessment results more scientific and comprehensive, but also allows the flight standard index derived from this formula to intuitively reflect the pilot's skill level, providing a clear direction for flight training. This helps to improve the pilot's operational skills in a targeted manner, thereby enhancing the effectiveness of flight simulation training and ensuring flight safety and training quality.

[0115] As one embodiment of the present invention, in step S17, the process of determining the flight standard level between the (n-1)th and nth synchronization key time points of the flight simulator cockpit is as follows:

[0116] When 0 < B n When R1 is less than or equal to 1, the flight standard level between the (n-1)th and nth synchronization critical time points in the flight simulator cockpit is unqualified.

[0117] When R1 < B n When R2 is less than or equal to 2, the flight standard level between the (n-1)th and nth synchronization critical time points in the flight simulator cockpit is qualified.

[0118] When R2 < B n When R3 is ≤, the flight standard level between the (n-1)th and nth synchronization key time points in the flight simulator cockpit is good;

[0119] When R3 < B n When the value is ≤1, the flight standard level between the (n-1)th and nth synchronization key time points in the flight simulator cockpit is excellent;

[0120] Among them, R1, R2 and R3 are preset comparison values; R1, R2 and R3 satisfy R3>R2>R1, and the specific values ​​of R1, R2 and R3 can be set by the staff according to the above relationship, such as letting R1=0.85, R2=0.92 and R3=0.97, which is not restricted here;

[0121] Through the above technical solution, this embodiment not only provides clear and quantitative evaluation standards for flight simulation training, enabling staff to accurately judge the performance level of pilots between adjacent key synchronization time points, facilitating targeted guidance and feedback; the division of different levels also helps pilots clarify the direction of their skill improvement, motivating them to continuously improve their operational actions, enhance flight quality and synchronization, thus helping to improve the effectiveness of flight simulation training, ensure flight safety, and provide strong support for cultivating high-quality pilots.

[0122] As one embodiment of the present invention, the data recording and analysis server is used to acquire flight status information and pilot operation data in real time, and generate training evaluation reports to provide to the command terminal; the training evaluation includes flight standard levels between each synchronous key time point;

[0123] Through the above technical solution, this embodiment acquires information in real time through a data recording and analysis server and generates a training evaluation report containing the flight standard level at each synchronous key time point, which is then provided to the command terminal. Command personnel can fully grasp the training situation and adjust training plans and strategies in a timely manner. Pilots can also accurately locate their own problems based on the report and make targeted improvements. This real-time and comprehensive evaluation and feedback mechanism further improves the efficiency and quality of flight simulation training, lays a solid foundation for pilot growth and flight safety, and powerfully promotes the development of flight training towards a more scientific and precise direction.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
