However, there remains a lack of trajectory management methods tailored to FRO that can effectively address the challenges of unstructured traffic flows, high traffic complexity, and uncertain weather conditions. This paper proposes a novel multi-module framework for 4D free-routing trajectory management, including trajectory prediction, airspace configuration, and strategic and tactical trajectory planning. Trajectory prediction incorporates ensemble-based weather forecasts to address uncertainty. A routing method tailored to FRO is adopted, combining a two-layer network with a K-shortest path algorithm to generate alternative routes. The core of this framework is a strategic trajectory planning method, integrating flow management and conflict management to optimize safety, efficiency, and flexibility. A complexity metric based on the linear dynamical system is adopted for safety evaluation. A distributed multi-objective optimization method is designed based on the decomposition mechanism, solving subproblems in parallel. The proposed framework is validated through a simulation scenario based on historical data from the western China airspace. Results demonstrate that the proposed method reduces operational risk by 88.52 % and increases flexibility by 51.66 %, with only a 6.84 % increase in cost. Additionally, trade-offs among three objectives are identified from non-dominated solutions, and a multi-criteria decision-making method guides the selection of the ideal solution and maneuver type. The proposed method also demonstrates high computational efficiency, making it a practical decision-support tool for future free-route operations.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"128 ","pages":"Article 102831"},"PeriodicalIF":3.9,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is essential to pay close attention to the efficiency of airlines worldwide. Currently, most studies do not consider the heterogeneity of airlines and treat all types of airlines as homogeneous decision-making units for efficiency evaluation. The results of the airline energy efficiency evaluation are biased. In this study, the meta-frontier model and the Epsilon-Based Measure (EBM) model are combined to measure the efficiency of airlines and, at the same time, open the internal operation process of the airline and analyze the aviation efficiency—three-stage efficiency of company operations, services, and sales. The results show that the efficiency value of the operation stage is the lowest, and the number of high-efficiency airlines in the operation stage is the least. Most airlines' inefficiency comes from the Operations stage. The efficiency under the meta-frontier does not exceed the corresponding efficiency under the group frontier, and ignoring the impact of heterogeneity will bias the airline's energy efficiency evaluation.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"127 ","pages":"Article 102829"},"PeriodicalIF":3.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144134600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The narrow aisle space within aircraft cabins, due to layout limitations, significantly restricts evacuation behavior, thereby escalating the complexity of evacuation procedures. This work studies the impact of common emergency-limiting factors such as obstacle types, initial movement speeds, aisle widths, and movement modes on personnel avoidance behavior within aircraft cabins. Research has found that the presence of suitcase obstacle primarily influenced the choice of avoidance behavior through subjective factors such as movement mode and initial speed. Conversely, in scenarios with pedestrian obstacles, avoidance behavior is shaped by both subjective factors and the evacuation environment (aisle width, obstacle type). Regarding movement trajectory, the lateral movement range of pedestrians is mainly related to the width of the aisle. At the same time, the lateral deviation of pedestrian movement trajectory will be adjusted according to the movement mode and obstacle type, and the safe distance for pedestrians to avoid the obstacles is approximately 0.5 m–1.5 m. In addition, research has found that in a 0.4m wide and obstacle-free aisle, the need for \"obstacle-free\" evacuation has been met, and the speed no longer increases with the width of the aisle. The aisle width is the main factor affecting the distribution of the average movement speed range. When there is suitcase obstacle, the frequency distribution of pedestrians' movement speed is related to their movement mode. The low-speed frequency of the \"individual\" is significantly higher than that of the \"group\".</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"127 ","pages":"Article 102825"},"PeriodicalIF":3.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the combination, backtracking, and following behaviors of passenger groups with specific social statuses, as well as the evacuation behavior of disabled groups using wheelchairs with the assistance of auxiliary personnel, we assess the influence of group behavior on evacuation efficiency employing the multi-forces floor field cellular automaton model. This model accounts for the logical differences in evacuation behaviors between different-sized and disabled groups. Through simulation, we analyze the effect of the timing of disabled groups joining the evacuation process on the evacuation duration and efficiency of different cabin segments. What is more, we examine the spatial distribution of groups of various sizes during the evacuation process. The results indicate that the early integration of disabled groups has a minimal overall impact, while their delayed involvement exacerbates the imbalance in exit usage time. The presence of groups prolongs the total evacuation time, with pairs exhibiting a denser spatial structure compared to larger groups. The negative impact brought by groups increases with the size of the group.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"127 ","pages":"Article 102819"},"PeriodicalIF":3.9,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reveals that SMS components (namely safety policy, safety risk management, and safety assurance) and the relative position of a Part 145 repair station in the social network can predict safety promotion performance. The data indicates that four predictors (i.e., all SMS components and one social network metric) are significant in this model, and the resulting regression equation predicts 78.6 % of the variance.

By analyzing Nordic aviation travel data, airport distances, natural resource potentials, fuel usage, policy measures, stakeholder positions, technological readiness levels, legal issues, and other relevant factors, we propose a dual approach. First, on short-haul routes, battery electric aircraft may be used, once the technology matures within the next years. Second, on medium- and long-haul routes, in the foreseeable future sustainable aviation fuels (SAFs) and, if available, hybrid and hydrogen technology.
