Knowing the airtime and the maximum range that the UAVs, which are used in critical missions, especially in the military field, are important for the reliability of the mission to be carried out. Therefore, in this study, the creation of a data set to calculate the flight time and range of the UAV using the prognostic method, which is one of the heuristic methods, is discussed. \u0000For this purpose, a fixed-wing UAV was used in this study to create the data set to be used in the prognostic method. The UAV used in flights has a weight of 2.5 kg, a wingspan of 1.3 m, and a body length of 1 m. In addition, thanks to the control card used in the UAV, both manual and autonomous flights were made. The flight data of the UAV was transferred to the Ground Control Station instantly. \u0000As a result, data sets were obtained from manual and autonomous flights to be used in the prognostic method. By using these data sets, it will be possible to calculate the duration and range of the UAV in the future flights.","PeriodicalId":86256,"journal":{"name":"The Journal of aviation medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88807063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a virtual environment application was developed, specifically focusing on the examination of Built-In Test Equipment (BITE) test procedures conducted by maintenance personnel during aircraft maintenance. The application included the design of a Multi-Function Control and Display Unit (MCDU) in the virtual environment. The benefits and limitations of the virtual environment application were discussed, highlighting how the challenging and risky working conditions can be efficiently transformed into practical training scenarios in various contexts, promoting the development and reinforcement of skills for personnel. Despite the extensive use of multi-user virtual environments in various fields, it is evident that there is scarce research conducted in the aviation maintenance and repair sector.

Initially, flight restrictions were implemented due to the Covid-19 pandemic, and airline companies were also affected by government-imposed social distancing measures. Economically, the Covid-19 pandemic has been particularly damaging to passenger transportation, with some countries experiencing a recovery but others facing employment issues in the industry. Sociologically, there has been an increase in reluctance to fly and changes in consumer behavior and habits, with a decrease in demand for unnecessary products. This process has also led to a number of positive developments from a technological standpoint, such as the rapid development and deployment of new vaccines and health monitoring technologies, as well as a decrease in emissions from the industry. This study is original in its examination of the Covid-19 pandemic impacts on the aviation industry using a PESTEL analysis. Based on the study's findings, strategies should focus on restructuring the aviation industry for Covid-19 pandemic readiness and recovery, including promoting restructured travel packages, low-cost flights, and popular routes. Emphasis on energy efficiency and environmental sustainability is crucial.","PeriodicalId":86256,"journal":{"name":"The Journal of aviation medicine","volume":"142 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80217290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were carried out on Ball-On-Disc wear device under 1, 3 and 5 N loads at room temperature. 3D optical microscope was used to determine the volume losses in the samples. The worn surface morphology of the samples was examined with the help of SEM (Scanning Electron Microscopy). In the test results, the volume losses of the samples increased depending on the increasing loads and shear rate. It has been understood that the change of the laying angle is important in the dry-sliding resistance of the samples. The wear resistance of the samples produced with 45 degree laying was better at both sliding speeds and all loads. It has also been understood that the laying angle is also effective in the coefficient of friction. Delamination, plastic deformation type dominant wear mechanisms have occurred.","PeriodicalId":86256,"journal":{"name":"The Journal of aviation medicine","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86435360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First of all, conceptual design work was done. Wing and tail, which are the main carriers, were selected to ensure maximum liftt, minimum drag and stability of the UAV. Liquid fuel engines were preferred due to their high power and airtime. The engine, which enables the controlled and uncontrolled flight of the UAV, has been run-in to make it safer and more efficient before being used in real-time flights. Profiles were selected by analyzing the tail set consisting of the rudder and the elevator. The nose cone of the unmanned aerial vehicle was produced by improving the aerodynamic performance. In the aircraft geometry, the passive morphing mechanism, which is performed once before the flight, and the active morphing mechanism, which is performed continuously during the flight, are manufactured using servo motors. This improved the flight performance and made it possible to fly in some unfavorable conditions. The most basic superior feature of the manufactured UAV from the existing UAVs is its ability to morphing.","PeriodicalId":86256,"journal":{"name":"The Journal of aviation medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78724333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this scope, the aim of this study is to determine and weight the strategies that forwarders operating in the air cargo sector can implement to increase their business volumes, using the studies in the literature, interviews with 10 experts working in different forwarder companies in Turkey, and the AHP method. Although strategies for companies to increase their business volumes examined in various studies, there is no study specifically for 'Air cargo transport companies'. In addition, any study using the AHP method for the sector has not been found in the literature. In this context, the study is unique in terms of sectoral practice and methodology.
