Abstract
Description
Technical Field
[0001] This invention relates to the field of operational performance evaluation technology, and specifically to a method for evaluating the autonomous operational performance of civil aviation. Background Technology
[0002] With the continuous development of the air transport industry and the constant growth of air traffic volume, the existing air traffic management system faces increasingly severe safety and efficiency challenges. The traditional ground control model is ground-centric, with aircraft relying primarily on ground commands for path planning and adjustments throughout the flight, resulting in low crew involvement. While this model has a mature technological system for ensuring safety, it suffers from problems such as decision-making delays, high communication loads, and insufficient operational flexibility under complex weather conditions, multi-aircraft collaborative operations, and high-density airspace operations, making it difficult to meet the development needs of future intelligent air transport systems.
[0003] To adapt to the needs of future intelligent flight and efficient operation, the International Civil Aviation Organization (ICAO) and major aviation powers have successively proposed development visions based on Autonomous Operations. These visions aim to enable aircraft to make autonomous judgments, plans, and executions through integrated air-ground situational awareness sharing and collaborative decision-making. The integrated air-ground autonomous operation mode, while adhering to existing flight rules, centers on the aircraft and achieves real-time perception and dynamic decision-making of the surrounding operating environment through two-way situational awareness sharing between the airborne and ground systems. Its core objective is to fully leverage the aircraft's performance potential, improving operational efficiency and reducing energy consumption and air-ground workload while ensuring safety.
[0004] In this mode, aircraft can autonomously assess their flight status based on multi-source information fusion, including Automatic Dependent Surveillance-Broadcast (ADS-B), Navigation Satellite System (GNSS), weather radar, ground surveillance, and communication links. This allows the crew to conduct digital negotiations with ground control units, enabling autonomous operations such as adjusting flight intervals, optimizing routes, and correcting flight paths. Through this process, a new operational paradigm of limited autonomy and collaborative decision-making is formed between air and ground.
[0005] In response to the rapid development and complex application scenarios of the integrated air-ground autonomous operation mode, there is an urgent need to establish a scientific and systematic performance evaluation index system and evaluation method. This evaluation system should cover multiple dimensions, including autonomous operation capability, safety, operational efficiency, economy, environmental impact, and personnel workload, and comprehensively assess the overall benefits of the operation mode through a combination of quantitative and qualitative methods.

[0026] Figure 2 The schematic diagram of the principle structure of the civil aviation autonomous operation performance evaluation method provided by the present invention. Detailed Implementation
[0027] To better understand the above-described objectives, features, and advantages of the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other. Furthermore, the present invention can be implemented in other ways different from those described herein; therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0028] This invention first extracts autonomous operation scenarios and environments. The system extracts key operational information from measured samples obtained from laboratory integrated verification environments and flight test environments, including meteorological, airspace, ground operating conditions, flight plans, air-to-ground surveillance, and operational restrictions, to provide data support for subsequent matching and evaluation. Then, based on a typical day discrimination method, historical data is matched to identify the historical model closest to the current scenario. Matching with historical models provides a reference for performance evaluation. Finally, the background and typical scenarios of air-to-ground information sharing and collaboration are studied and summarized, constructing autonomous operation performance evaluation indicators from five areas: safety, efficiency, economy, environment, and personnel workload. Multiple performance indicators are then calculated by comparing historical and measured data.
[0029] To illustrate the effectiveness of the method proposed in this invention, the following detailed description of the above technical solution is provided through a specific embodiment. A specific embodiment of this invention is as follows: Figure 1 , Figure 2 As shown, a method for evaluating the autonomous operation efficiency of civil aviation is disclosed, and the specific implementation steps are as follows: Step S1: Obtain historical operational information data. The historical operational information data includes operational information accumulated during civil aviation operations, including meteorological, airspace, ground operating conditions, flight plans, air-to-ground surveillance, and operational restriction information. In this step, the present invention first establishes a historical database of civil aviation operation information. The historical database is obtained by aggregating and organizing the operation information of various civil aviation operation systems. The operation information includes meteorological, airspace, ground operation conditions, flight plans, air-to-ground surveillance, and operation restriction information.
[0030] In some embodiments, the operational information may come from airline ground support systems, meteorological observation systems, air traffic control and dispatch systems, automated monitoring systems, and airport operations control platforms, etc.
[0031] Specifically, the meteorological, airspace, ground operating conditions, flight plans, air-to-ground surveillance, and operational restrictions information are described in detail below.
[0032] Meteorological information includes values for various meteorological elements such as temperature, air pressure, humidity, wind speed, wind direction, precipitation, and thunderstorms. Meteorological information can be further collected and extracted through meteorological observation systems.
[0033] Airspace information includes dynamic characteristics such as airspace type, structure, control rules, altitude and speed restrictions. Airspace information can be automatically synchronized with existing air traffic control and dispatch systems to obtain airspace type, boundaries, altitude layer divisions, control rules, and corresponding flight restrictions, reflecting real-time changes in airspace adjustments and usage.
[0034] Ground operations information includes basic airport information, runway conditions, navigation facilities, signs and markings, and air traffic control services. This information can be comprehensively collected through airline ground support systems combined with airport announcements, airport capacity data, and ground traffic flow data.
[0035] Flight plan information includes information such as departure and arrival airports, routes, and track matching. Flight plan information can be obtained by analyzing flight schedules and other data provided by airline operating systems and air traffic control systems.
[0036] Air-to-ground surveillance information includes the flight path data of the aircraft and other aircraft, flight traffic, and airspace density. Flight path data includes latitude, longitude, altitude, speed, and heading. Air-to-ground surveillance information can be collected by automated surveillance systems.
[0037] Operational restrictions include weather restrictions, airport operational restrictions, aircraft performance restrictions, and flight rule constraints, which can be obtained through airport operations control platforms, etc.
[0038] Step S2: Based on the historical data of the operation information, establish multiple historical models. Each historical model is used to represent different autonomous operation scenarios of civil aviation. Each autonomous operation scenario includes corresponding benchmark performance indicators. In this step, the present invention first establishes six typical autonomous operation scenarios, determines the types of performance indicators for each autonomous operation scenario, then classifies the historical data of operation information into these six typical autonomous operation scenarios to form six historical models, and finally calculates the performance indicators corresponding to each historical model based on the historical data of operation information, and performs post-processing to obtain the benchmark performance indicators.
[0039] Step S2-1: Establish multiple typical autonomous operation scenarios and determine the types of performance indicators for each autonomous operation scenario.
[0040] In this step, the various typical autonomous operation scenarios of the present invention include: autonomous rerouting operation under severe weather conditions, straightening operation under flexible airspace use, single-aircraft trajectory-based operation (single-aircraft TBO), emergency response under the influence of strong convection along the route, autonomous wake separation operation in high-density scenarios, and autonomous decision-making operation for approach procedures.
[0041] To scientifically and comprehensively evaluate the performance of different autonomous operation scenarios, a complete performance indicator system is first constructed in the specific embodiments of this invention. This system systematically defines various evaluation indicators from five dimensions: safety, efficiency, economy, environment, and personnel workload, forming a complete indicator library required for evaluation.
[0042] In this step, the present invention defines the types of performance indicators, including: safety performance evaluation indicators, efficiency performance evaluation indicators, economic performance index indicators, environmental benefit indicators, and the load on the unit and control personnel.
[0043] Each performance indicator includes several specific indicators. Among them, the safety performance evaluation indicators specifically include: Accident / Incident Rate, Separation Violation Rate, Situational Awareness Consistency Rate (SACR), Perception Loss Rate (PLR), Potential Conflict Detection Rate (PCDR), Successful Conflict Resolution Rate (SCRR), Emergency Response Delay (ERD), and Safety Redundancy Coverage (SRC).
[0044] Efficiency and performance evaluation indicators specifically include: Flight Density, Peak Traffic Load, Average Traffic Load, Airspace Utilization Rate, Temporary Route Availability (UR), Temporary Route Potential Availability (PUR), Number of Flights Using Temporary Routes (RUS), Number of Flights Using Temporary Routes Potentially (PRUS), Temporary Route Actual Utilization Rate (RAU), Route Length Utilization Rate, and Delay Rate.
[0045] The specific indicators of the economic efficiency index include: total miles saved (FER), average miles saved (PFE), potential total miles saved (FEL), flight economy contribution (FEO), potential miles saved ratio (RFEL), actual flight efficiency (AFE), and total fuel savings (TFS).
[0046] The specific environmental benefit indicators include: pollutant gas emission benefit (PGB), noise pollution benefit (NPB), total CO2 emission reduction (TCR), potential CO2 emission reduction (PCR), potential CO2 emission reduction ratio (RPCR), and potential mileage saving ratio (RFEL).
[0047] The specific loads of the crew and controllers include: influencing factor coefficient K, task unit load value B, multitasking coefficient D, task conflict value C, traffic density load index, communication load index, interface interaction compliance index, and time characteristic load index.
[0048] The above are all the performance indicators provided by this invention. Based on the core operational characteristics, key performance objectives, and main potential risks of each autonomous operation scenario, this invention selectively filters and combines indicators from the aforementioned indicator library to construct a dedicated set of evaluation indicators highly matched to the scenario. This selection criterion ensures the accuracy and relevance of the evaluation. Different types of performance indicators are provided for each autonomous operation scenario, described in detail below.
[0049] (1) For autonomous flight rerouting operations under severe weather conditions, the indicators include: Safety performance indicators: air-to-ground situational consistency rate, minimum separation maintenance violation rate, and effective avoidance rate; Efficiency and performance indicators: delay rate, route length utilization rate; Economic efficiency indicators: Total fuel savings and actual flight benefits; Environmental benefit indicators: Total CO2 emission reduction; Personnel workload index: Pilot workload.
[0050] (2) For flexible use of airspace and straightening of curves, the indicators include: Safety performance indicators: actual utilization rate of temporary routes, utilization rate of route length, and utilization rate of airspace; Economic efficiency indicators: total mileage savings, average mileage savings, total fuel savings, and potential total mileage savings; Environmental benefit indicator: Total CO2 emission reduction.
[0051] (3) For single-aircraft trajectory-based operations (single-aircraft TBO), the metrics include: Safety performance indicators: Minimum interval violation rate; Efficiency and performance indicators: Delay rate; Economic efficiency indicator: Total fuel savings.
[0052] (4) For emergency response to severe convective weather along flight routes, the indicators include: Safety performance indicators: emergency response delay, effective avoidance rate, and air-to-ground situational consistency rate; Efficiency and performance indicators: Delay rate.
[0053] (5) For autonomous wake interval operation in high-density scenarios, the indicators include: Safety performance indicators: Minimum interval violation rate; Efficiency and performance indicators: peak traffic flow, traffic density, airspace utilization, and delay rate.
[0054] (6) For the autonomous decision-making operation of the entry procedure, the indicators include: Efficiency and performance indicators: Route length utilization rate; Economic efficiency indicator: Total fuel savings; Environmental benefit indicators: noise pollution benefit, total CO2 emission reduction; Personnel workload index: Pilot workload.
[0055] For autonomous flight detours in adverse weather conditions, the key lies in whether the aircraft can safely and efficiently complete its flight in a dynamic and complex environment after deviating from its planned route. Therefore, air-to-ground situational awareness rate and effective avoidance rate are selected to measure its safety assurance capability after deviation. At the same time, flight detours inevitably lead to changes in flight path and time, so delay rate and route length utilization rate are selected to quantify their impact on operational efficiency. The economic and environmental benefits are assessed by total fuel savings and total CO2 emission reductions, while pilot workload is used to assess the impact on personnel under abnormal conditions.
[0056] For scenarios involving flexible airspace use and straightening off-traffic routes, the core objective is to shorten flight distances through temporary routes, thereby improving economy and efficiency. Therefore, the selection of indicators focuses heavily on quantifying benefits, directly using economic indicators such as total mileage savings and total fuel savings, and environmental indicators such as total CO2 emission reduction, to measure its main benefits. Indicators such as the actual utilization rate of temporary routes and airspace utilization rate are used to evaluate the actual performance of this strategy in improving airspace resource utilization efficiency.
[0057] For autonomous wake separation operations in high-density scenarios, the essence is to improve airspace capacity and operational efficiency by shortening the intervals while ensuring safety. Therefore, the most important aspect of safety assessment is maintaining a low violation rate for minimum intervals to monitor core risks. Its operational benefits are directly reflected in indicators such as peak traffic flow, traffic density, and delay rate, which directly reflect the effectiveness of capacity improvement.
[0058] Using the above method, this invention selects the most representative performance items based on the key operational risk points, operational efficiency requirements, and practical application value corresponding to each scenario, forming a combination of performance evaluation indicators that match different scenarios, thereby achieving a scientific, systematic, and targeted evaluation of performance under various autonomous and complex operating environments.
[0059] Step S2-2: Classify the historical data of the operation information into the various typical autonomous operation scenarios to form various historical models.
[0060] In this step, the historical data of the operation information is classified and divided into these 6 typical autonomous operation scenarios, thereby obtaining the historical data of the operation information corresponding to the 6 autonomous operation scenarios.
[0061] In some embodiments, the original information of the historical operation information data already records the operation scenario at that time, and the historical operation information data can be classified according to the original information; In some embodiments, information such as the actual flight trajectory and planned route of a flight can be obtained from flight plans, air-to-ground surveillance, and other information in the historical operational information data. By judging the flight plans and air-to-ground surveillance, the classification of the historical operational information data can be automatically completed.
[0062] Step S2-3: Calculate the performance index corresponding to each historical model based on the historical data of the operation information, and perform post-processing to obtain the benchmark performance index.
[0063] In this step, the performance indicators corresponding to each piece of operational information in the historical data of each historical model can be specifically calculated. The performance indicators can be averaged or clustered to obtain the corresponding benchmark performance indicators.
[0064] In some embodiments, after completing the data classification in step S2-2, performance indicators are batch calculated and statistically analyzed for the six scenario-specific historical model databases formed above. First, based on the performance indicator types preset for each scenario in step S2-1, the corresponding calculation formulas are called. Taking the historical model database of "autonomous wake turbulence interval operation in high-density scenarios" as an example, each historical time segment in the database can be traversed to extract data such as traffic flow and aircraft intervals within that time period, and formulas such as "peak traffic flow" and "minimum interval maintenance violation rate" are applied for calculation to obtain a series of discrete raw performance indicator values. After completing the calculation for all historical data points in a scenario database, statistical post-processing is performed on the historical data points.
[0065] Specifically, this involves calculating the mean, median, standard deviation, and key percentiles (such as the 75th and 90th percentiles) for each performance indicator, or performing clustering operations on each performance indicator. This ultimately forms a multi-dimensional set of benchmark performance indicators. For example, for the indicator "delay rate," the benchmark value may not be a single numerical value, but rather a comprehensive reference system that includes "historical average delay rate," "historical delay rate fluctuation range (defined by the standard deviation)," and "historical high delay level (defined by the 90th percentile)." The benchmark performance indicators obtained in this way not only objectively reflect the historical average performance in this scenario but also provide a quantitative understanding of performance stability and historical extreme cases, thus establishing a reference benchmark for subsequent comparative evaluation with real-time operating scenarios.
[0066] Step S3: Obtain the operational information to be evaluated, match the operational information to be evaluated with multiple historical models, and obtain the current autonomous operation scenario; In this step, the present invention acquires the operational information to be evaluated and the feature information of various historical models, compares and matches them based on the feature information, and finally determines the current autonomous operation scenario corresponding to the operational information to be evaluated.
[0067] In some embodiments, a series of key feature parameters, such as flight trajectory, flight plan, and operating environment, can be obtained from the flight plan, air-to-ground surveillance, and other information in the operational information to be evaluated, and these parameters can be combined into a real-time feature vector representing the current operational status.
[0068] The matching process of this invention employs a pre-built and trained scene classification model. This classification model can be a machine learning-based model, such as a Support Vector Machine (SVM), Gradient Boosting Decision Tree, or Deep Neural Network (DNN).
[0069] In some embodiments, during the training phase of the classification model, the model can learn a large number of feature vectors and their corresponding scene labels from the historical database of six typical scenarios in step S2-2. During the evaluation phase, the real-time scene matching engine takes the newly generated real-time feature vectors as input, and the model calculates the probability or confidence score of the real-time feature vector belonging to each typical autonomous operation scenario based on its internally learned decision boundaries or patterns. Finally, the engine selects the scenario category with the highest probability or a confidence score exceeding a preset threshold as the autonomous operation scenario matched to the current operational information to be evaluated. For example, if the real-time feature vector has high weights for features such as "high traffic density," "small aircraft spacing," and "specific approach procedures," the classification model will identify it as "autonomous wake turbulence interval operation in a high-density scenario" with a very high probability. Through this matching mechanism based on feature vectorization and machine learning classifiers, this invention can achieve rapid, accurate, and automated scene identification of current complex operational situations.
[0070] Step S4: Calculate the actual performance indicators corresponding to the current autonomous operation scenario based on the operational information to be evaluated; In this step, the present invention calculates the current operational information to be evaluated, and obtains the specific values of the actual performance indicators corresponding to the current autonomous operation scenario. As described in step S1, the operational information to be evaluated includes the current meteorological, airspace, ground operation conditions, flight plan, air-to-ground surveillance, and operational restriction information.

This represents the multi-task load factor matrix. These represent the multitasking load coefficient values for visual input, auditory input, cognitive input, motor output, and language output channels, respectively. This indicates the matrix transpose.
[0168] This invention provides a specific implementation of a mission-based pilot workload prediction model. The model is constructed as a multi-module matrix calculation framework, designed to comprehensively evaluate a pilot's workload at a specific moment. Its core calculation model utilizes a comprehensive formula. To achieve this, the formula integrates the functions of the influencing factors module, task unit module, conflict task module, and multi-task module. The model first decomposes the tasks performed by the pilot into five independent processing channels based on Wickens' multi-resource theory: visual perception (v), auditory perception (a), cognition (c), action output (k), and language output (s), laying the foundation for subsequent matrix calculations.
[0169] In this embodiment, the computational input of the model consists of five key matrices. First is the task unit existence matrix A(t) = [ , , , ], where each element is a binary value (0 or 1). , , , These are used to characterize in real time whether a task exists in the five channels (visual, auditory, cognitive, motor, and language) at time t. Next is the single-task load value matrix B(t), a diagonal matrix whose diagonal elements [ , , , ] represents the base load value of a single task unit on each channel; if a channel has no task, its load value is replaced by a unit value of 1 to ensure the effectiveness of matrix operations.
[0170] To accurately model load variations during multi-task parallel processing, this implementation introduces a task conflict coefficient matrix C(t) and a multi-task load coefficient matrix D(t). C(t) is a row vector. , , represent the task conflict coefficients on each channel, used to quantify the additional load caused by multiple tasks occurring simultaneously (i.e., conflicting tasks) within the same channel. Their coefficient values reflect the nonlinear superposition effect of the load; the coefficient value for conflict-free channels is 1. D(t) is a column vector. , respectively, represent the task coefficient matrix on each channel, used to quantify the impact of resource allocation and parallel operation on the total load when tasks on different channels are executed simultaneously (i.e., multitasking). The coefficient value characterizes the relationship between the multitasking load and the arithmetic sum of the individual task loads. The coefficient value of the channel where no multitasking occurs is 1.
[0171] To incorporate situational factors such as the external environment and pilot condition, the model also includes an influencing factor coefficient K(t). This coefficient is a scalar used to correct and adjust the baseline workload value calculated based on the mission. The influencing factors broadly cover four aspects: flight mission characteristics (e.g., normal / abnormal conditions, time pressure, flight phase), flight environment (e.g., weather, terrain, aircraft type), cockpit human-machine interface (e.g., visual cleanliness, operational logic), and individual pilot factors (e.g., fatigue, total flight time). Through this coefficient, the model can dynamically reflect workload fluctuations under different situations.
[0172] In this implementation, all key coefficients and load values were obtained through a series of hierarchically designed experiments, and a database was established. For example, the flight phase coefficient in the influencing factor coefficient K(t) was obtained by controlling the flight phase as a single variable in simulated flight, having pilots perform the same tasks, and evaluating it using a 1-10 workload subjective evaluation scale. Regression analysis was then used to obtain the coefficient values of each phase (e.g., takeoff 0.834, approach 1.257) relative to the baseline. Similarly, the task unit load value B(t) (e.g., "monitoring altitude" 3.73), the task conflict coefficient C(t) (e.g., visual conflict coefficient 1.14), and the multi-task coefficient D(t) (e.g., visual-operation combined task coefficient) were all measured and calibrated through carefully designed single-task, same-channel conflict task, and different-channel multi-task experiments, combined with subjective evaluation scales and regression analysis methods, thereby ensuring the effectiveness and practical application value of the entire prediction model.
