Approach and sequencing in terminal airspace is one such phase of flight, at which congestion has high cost in fuel and management of operational complexity. A novel solution for mitigating these negative impacts in a simple and cost-effective manner are welcome. The present study evaluated the efficacy of air traffic control operations combining fixed-flight path angle descent and speed control techniques, on fuel efficiency and pilot operability. We designed a series of flight scenarios for Kansai International Airport arrivals and ran them in a simulation environment. The fixed-flight path angle descent facilitates more precise and reliable prediction of arrival trajectory and reduction in air traffic control operation complexity. The fixed-flight path angle descent procedure has additional anticipated benefits, namely, reduction in fuel burn and the ability to control aircraft speed without compromising fuel efficiency. It may therefore be a viable contender for arrival sequencing and separation maintenance tactic, in place of today’s common vectoring technique. Furthermore, the fixed-flight path angle descent can be performed without modifications or additions to the current onboard electronic equipment of aircraft. This paper demonstrates that combination of fixed-flight path angle descent and speed control performed in a commercial aircraft has the same utility in the route extension by vectoring performed by air traffic controllers during congested air traffic and can be performed while achieving reduction in fuel consumption. Flight simulator tests of an aircraft approaching Kansai International Airport from a southwestern or western direction show that combination of fixed-flight path angle descent and speed control can reduce fuel consumption by up to approximately 260 pounds per flight, without causing noticeable problem in the aircraft operation. Furthermore, the relationship between the en-route sector, upstream of the terminal airspace, and the angle selected for the fixed-flight path angle descent, the operational issues for performing the proposed speed control method are discussed.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"128 ","pages":"Article 102799"},"PeriodicalIF":3.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678732","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 complexity not only heightens the likelihood of surface conflicts and unsafe events, but also has a substantial impact on both the operational efficiency and safety of airport operations. Current research on airport surface hotspots mainly focuses on conflict hotspots and risk hotspots, and fewer studies are conducted on busy hotspots. In order to fill this research gap, this paper proposes an accurate matching method of airport surface trajectory and taxiway system based on Hidden Markov Algorithm. And establishes an indicator system to characterize airport surface taxiway, which is used to comprehensively reflect the airport surface taxiway operation efficiency. On this basis, an Airport Surface Hot-Taxiway-Segment Recognition Model (ASHRM) is proposed which innovatively introduces the new concept of hot index to quantify and measure the popularity of taxiway segments, thus realizing the recognition of hot taxiway segments. Through the experimental analysis of real data from SZX Airport, the results show that the recognized hot taxiway segments are consistent with actual airport operations, and the cumulative traffic flow is identified as the most critical factor affecting the formation of hot taxiway segments. This method not only provides a scientific basis for the operational management and efficiency assessment of airports, but also realizes the scientific recognition of hot taxiway segments in the dynamically changing airport surface transportation systems.</div></div>","PeriodicalId":14925,"journal":{"name":"Journal of Air Transport Management","volume":"127 ","pages":"Article 102822"},"PeriodicalIF":3.9,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931875","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}

With the increase in aviation demand, ASP has been garnered more attention in recent years. However, existing ASPs typically assume that the relationships between runways are either entirely independent or entirely interdependent, without considering the complex scenarios where runways have both dependent and independent relationships. Moreover, existing ASP research focusing on multi-objective aspects is relatively scarce, while it is essential to consider multifaceted needs in reality. Therefore, we have established a multi-objective mathematical model for the Aircraft Sequencing Problem with Complex Interdependent Runways (ASP-CIR), aiming to minimize the total delays and makespan. Different from the common lack of problem-specific structural design in existing ASP algorithms, or the need to improve structural strategies, we propose an Improved Multi-Objective Restart Variable Neighborhood Search (IMORVNS) algorithm based on the characteristic of the studied ASP-CIR. In the IMORVNS, we have designed several problem-specific structures guided by constraints, such as initialization and neighborhood search. We tested our new method on 30 different problem instances of three sizes and found it worked better than other recent algorithms.
