Dünyada küresel bir tehdit olarak varlığını sürdüren çevresel sorunlar, son zamanlarda hem medyada hem de akademide sıklıkla ele alınmaktadır. İş dünyasında farklı sektörlerde yer alan işletmelerin de çevresel sorunları göz ardı edemeyeceği ortadadır. Bu sektörlerin en önemlilerinden biri de havacılık sektörüdür. Sektörde, gürültü kirliliği başta olmak üzere hava, su, toprak kirliliği, doğal yaşama ve yaban hayatına zarar verici etkiler söz konusudur. Sektörde havaalanlarının kurulması ve havacılık faaliyetlerinin başlaması ile inşaat çalışmaları, atıkların artması, havaalanı çevresinde sanayileşmenin gelişmesi, enerji kaynaklarının hızla tüketimi, yerleşim alanlarının büyümesi, nüfusun artması ‘Çevre Yönetim Sistemi’ uygulamaları ile kontrol altına alınması önerilmektedir. Dünya’da havalimanlarında uygulanan çevre yönetim uygulamalarını başarılı yönetmek ve çevre bilincini tüm işletme genelinde yaymak için yeşil işletme stratejisi araştırılmaktadır. Yeşil işletme stratejisi, işletmenin tüm birimlerindeki çevresel konuları iş stratejisine entegre etme eğilimini ifade eder. Bu çalışmada çevresel bozulmayı durdurabilecek ve hatta çevre vb. unsurlar sonucunda çevre kirliliği de artmaktadır. Günümüzde havalimanlarındaki faaliyetler sonucunda ortaya çıkan çevre kirliliği etkisinin kontrol altına alınabilmesi için ‘Çevre yönetim sistemlerinin başarılı yönetilmesine katkı sağlayabilecek bir olgu olarak yeşil işletme stratejisi araştırılmaktadır. Buradan hareketle, yeşil işletme stratejisinin havaalanı çevre yönetim sisteminin başarısında bir alternatif olup olmayacağı kavramsal-teorik uygulama yöntemi ile tartışılmaktadır.

This study examines the development of the low-cost carriers (LCCs) in Australia’s export and import air freight markets. The study period is from 2004 to 2020. The study used a qualitative instrumental case study research approach. The data gathered for the study was examined by document analysis. The study found that the development of the low-cost carriers (LCCs) share of Australia’s annual export and import air freight markets occurred in three distinct phases. In the initial phase, 2004-2005, the market was served by just one low-cost carrier (LCC) Pacific Blue Airlines, who did not transport any export or import air freight in 2004. In 2005, the airline made a strategic policy decision to transport air freight. Phase 2 saw the inception of international services by Jetstar Airways in 2006. Jetstar Airways immediately gained import and export air freight traffic. The third phases took place from 2007 to 2020, when the major Asia-based low-cost carriers entered the market, starting with AirAsia-X in 2007. The low-cost carriers (LCCs) annual air freight market growth rates oscillated substantially over the study period, particularly for export air freight traffic. Despite the strong growth, the low-cost carriers (LCCs) annual market export and import air freight shares are considerably lower than those of the dedicated all-cargo carriers and full-service networks carriers (FSNCs).
本研究考察了低成本航空公司(lcc)在澳大利亚进出口航空货运市场的发展。研究时间为2004年至2020年。本研究采用定性工具案例研究方法。为研究收集的数据通过文献分析进行了检验。研究发现,低成本航空公司(lcc)在澳大利亚年度进出口航空货运市场份额的发展经历了三个不同的阶段。在2004-2005年的初始阶段,市场仅由一家低成本航空公司(LCC)太平洋蓝色航空公司(Pacific Blue Airlines)提供服务,该公司在2004年没有运输任何出口或进口航空货物。2005年,该航空公司做出了一项战略决策,即运输航空货运。第二阶段是由捷星航空公司于2006年开始提供国际服务。捷星航空公司立即获得了进出口航空货运量。第三阶段是从2007年到2020年,亚洲主要的低成本航空公司进入市场,从2007年的亚航x开始。在研究期间,低成本航空公司(lcc)的年度航空货运市场增长率大幅波动,尤其是出口航空货运。尽管增长强劲,但低成本航空公司(lcc)的年度市场出口和进口航空货运份额远低于专门的全货运航空公司和全服务网络航空公司(FSNCs)。

Global competitiveness has become just as crucial in the rapidly growing world economy. For this reason, the problem of delivering the products to the consumer at the right place and time has become indispensable to survive in the global market and has brought the logistics factor to the fore. One of these logistics activities, the transportation sector, ensures that human needs are met at the desired place and on time. It has become essential to deliver products to target markets faster and safer than their competitors, and airplanes have been used in cargo and passenger transportation. The rapid technological change has also led to aircraft development used in cargo transportation. Thus, air cargo transportation, which is less risky and faster than other transportation modes, has come to the fore in time-bound and valuable goods. The main purpose of this study, which is carried out with the qualitative research method, is to determine and evaluate the effects of air cargo transportation on global competitiveness. In the study, firstly, the concept of air cargo transportation tried to be explained. Then, the literature review created the background of the study. In this context, the development process of air cargo transportation was discussed in terms of its historical, corporate, and economic development. Then, the types of aircraft used, airports, and cargo companies operating on a global scale, which are the elements of air cargo transportation, were examined. In addition to the high capacity and fuel efficiency produced by the current technology of the aircraft, the issue of further reduction of costs due to capacity increase by optimizing the loading problem has been mentioned. Finally, by analyzing the findings, the effects of air cargo transportation on global competitiveness were discussed and evaluated, and suggestions were made to increase this power. This article, which is a direct study on the effects of air cargo transportation on global competitiveness, is crucial as it will contribute to the literature.
在快速增长的世界经济中,全球竞争力已变得同样重要。因此,在正确的地点和时间将产品交付给消费者的问题已成为在全球市场中生存所不可或缺的问题,并使物流因素脱颖而出。这些物流活动之一,运输部门,确保人类的需求在理想的地点和时间得到满足。与竞争对手相比,将产品更快、更安全地送到目标市场已变得至关重要,飞机已被用于货运和客运。快速的技术变革也导致了用于货物运输的飞机的发展。因此,与其他运输方式相比,风险小、速度快的航空货物运输在有时限、有价值的货物运输中脱颖而出。本研究采用定性研究方法,主要目的是确定和评估航空货运对全球竞争力的影响。本文首先对航空货物运输的概念进行了阐述。然后,通过文献综述为本研究创造了背景。在此背景下,从航空货运的历史发展、企业发展、经济发展等方面论述了航空货运的发展历程。然后,检查了使用的飞机类型,机场和在全球范围内运营的货运公司,这些都是航空货物运输的要素。除了飞机现有技术所产生的高容量和燃油效率外,还提到了通过优化装载问题来增加容量从而进一步降低成本的问题。最后,通过对研究结果的分析,讨论和评价了航空货运对全球竞争力的影响,并提出了提高全球竞争力的建议。这篇文章,这是一个直接研究航空货运对全球竞争力的影响,是至关重要的,因为它将有助于文献。

This study aims to obtain new data that will mediate the development of safety culture by investigating the power distance, which is one of the cultural dimensions of communication, which causes accidents in aviation, through the assertiveness levels of the pilots and their social approval needs. The method of this research is quantitative, data were collected through online questionnaires. The population and the sample of the research are consisted of the civilian pilots in Turkey. The questionnaires were applied to 75 pilots. In male pilots participating in the study; The levels of "Instrumental Use of Power" and "Legitimation of Power", which are sub-dimensions of organizational power distance, are significantly higher than female pilots. In addition, it has been revealed that female pilots pay less attention to the judgments of others than male pilots. These results suggest that male pilots need more organizational power than female pilots. One of the results of the research is the strong positive relationship between the assertiveness level of the participants and "Consent to Power", which is one of the sub-dimensions of power distance; it is thought that this relationship stems from the social adaptation capacity of assertive individuals. The study also showed that the main factor determining the behavior of the employees is the organizational culture. Within this scope, sharing the accident reports of Turkish registered aircraft prepared by DGCA with researchers and institutions will contribute significantly to the need for resources.
本研究旨在通过飞行员的自信水平及其社会认可需求,对导致航空事故的沟通文化维度之一的权力距离进行调查,以获得调解安全文化发展的新数据。本研究的方法是定量的,通过在线问卷调查的方式收集数据。本研究的人口和样本由土耳其的民用飞行员组成。问卷调查了75名飞行员。在参与研究的男性飞行员中;组织权力距离的子维度“权力的工具性使用”和“权力的正当性”水平显著高于女性飞行员。此外,有调查显示,女飞行员比男飞行员更不注意别人的判断。这些结果表明,男性飞行员比女性飞行员需要更多的组织权力。研究发现,被试的自信水平与权力距离子维度之一的“权力同意”之间存在较强的正相关关系;人们认为这种关系源于自信个体的社会适应能力。研究还表明,决定员工行为的主要因素是组织文化。在此范围内,与研究人员和机构分享DGCA准备的土耳其注册飞机的事故报告将大大有助于满足资源需求。

In this study, the wing profile, which is difficult to calculate and determine, has been optimized with the help of Foilsim data and optimization algorithms. Foilsim data provided by NASA (National Aeronautics and Space Administration) and used by many researchers, especially in developing model airplanes, has been provided to use in aircraft wing shape optimization. Although Foilsim is a very useful simulation program for designers, it cannot be used effectively in optimization processes due to its web environment. Lift coefficient is needed for Lift equation in airfoil shape optimization. Lift coefficient depends on angle, camber, and thickness of airfoil Calculation of Lift coefficient is difficult and needs heavy mathematical equations or real experiments. By using Foilsim data and optimization algorithm (Artificial Neural Networks: ANN, Artificial Bee Colony: ABC), wing angle, camber and thickness values, which are difficult to determine and calculate, were estimated and comparative experiments of the values were made. (Fixed Lift, Fixed Speed, Fixed Wing Area). Experimental results have shown that it is a useful study for airfoil shape optimization. In short, in this study, by using the Foilsim data and the optimization algorithm to provide the lifting force determined by the designer, the most suitable angle, camber, thickness values of the wing, which are difficult to determine and calculate, are determined to enable the production of efficient aircraft. The user enters the desired lift value into the ABC optimization algorithm and finds the required wing properties for the desired lift value.
在本研究中,利用Foilsim数据和优化算法对难以计算和确定的翼型进行了优化。美国国家航空航天局(NASA)提供的Foilsim数据被许多研究人员使用,特别是在模型飞机的开发中,已提供用于飞机机翼形状优化。虽然Foilsim对于设计人员来说是一个非常有用的仿真程序,但是由于它的web环境,它不能有效地用于优化过程。在翼型形状优化中,升力方程需要用到升力系数。升力系数取决于翼型的角度、弧度和厚度,计算升力系数是困难的,需要大量的数学方程或实际的实验。利用Foilsim数据和优化算法(Artificial Neural Networks: ANN, Artificial Bee Colony: ABC),对难以确定和计算的翼角、弧度和厚度值进行了估计,并进行了数值对比实验。(固定升力,固定速度,固定翼面积)。实验结果表明,该方法对翼型优化设计具有重要意义。总之,在本研究中,利用Foilsim数据和优化算法,提供设计者确定的升力,确定最合适的机翼角度、弧度、厚度值,这些都是难以确定和计算的,使飞机生产高效。用户将期望升力值输入ABC优化算法,并找到期望升力值所需的机翼特性。

The Effect of Price Perception on Customer Loyalty in Airline Cargo Transportation 航空货运价格感知对顾客忠诚的影响
Pub Date : 2022-05-30 DOI: 10.30518/jav.1056998
Erkut Artik, A. Duygun
Airline cargo transportation is the preferred transportation system as the fastest transportation way today. However high costs also lead to high prices. Therefore, pricing is one of the issues that businesses should pay the most attention to when planning. Although competition over price is a competitive factor that businesses do not want to enter, this situation has become inevitable due to the intensity of the competition. To cope with this situation, it is beneficial for businesses to constantly measure and evaluate the price perception of customers. In addition, it is of great importance for every customer for airline cargo companies that want to stay afloat in a dynamic market. Providing unconditional customer satisfaction and turning these customers into loyal customers is the key to sustainable success for companies engaged in airline cargo transportation. Based on what has been described so far, it is possible to express the main purpose of this study in the form of investigating the effect of price perception on customer loyalty. The businesses using airline cargo transportation were included in the research and in this direction, research was carried out with 33 businesses operating in the Marmara Region and using airports in Istanbul. In the study, it was concluded that airline cargo price perception does not have a statistically significant effect on airline cargo customer loyalty. Finally, suggestions have been made to those interested in the subject.
航空货运作为当今最快的运输方式是首选的运输系统。然而,高成本也导致高价格。因此,定价是企业在规划时最应注意的问题之一。虽然价格竞争是企业不愿意进入的竞争因素,但由于竞争的激烈,这种情况已成为不可避免的。为了应对这种情况,企业需要不断测量和评估顾客的价格感知。此外,对于想要在动态市场中生存的航空货运公司来说,这对每个客户都是非常重要的。提供无条件的客户满意度并将这些客户转化为忠诚客户是从事航空货运的公司持续成功的关键。基于到目前为止所描述的,有可能以调查价格感知对顾客忠诚度的影响的形式表达本研究的主要目的。使用航空货物运输的企业被纳入研究,在这个方向上,对在马尔马拉地区经营并使用伊斯坦布尔机场的33家企业进行了研究。研究发现,航空货运价格感知对航空货运客户忠诚度的影响不具有统计学意义。最后,对那些对这个主题感兴趣的人提出了建议。

To cope with this situation, it is beneficial for businesses to constantly measure and evaluate the price perception of customers. \u0000In addition, it is of great importance for every customer for airline cargo companies that want to stay afloat in a dynamic market. Providing unconditional customer satisfaction and turning these customers into loyal customers is the key to sustainable success for companies engaged in airline cargo transportation. \u0000Based on what has been described so far, it is possible to express the main purpose of this study in the form of investigating the effect of price perception on customer loyalty. The businesses using airline cargo transportation were included in the research and in this direction, research was carried out with 33 businesses operating in the Marmara Region and using airports in Istanbul. \u0000In the study, it was concluded that airline cargo price perception does not have a statistically significant effect on airline cargo customer loyalty. Finally, suggestions have been made to those interested in the subject.","PeriodicalId":86256,"journal":{"name":"The Journal of aviation medicine","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76393576","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}

Determinants of Air Cargo Demand in The European Region 欧洲地区航空货运需求的决定因素
Pub Date : 2022-05-27 DOI: 10.30518/jav.1053662
Serdar Alnıpak, S. Kale
Air cargo demand estimation is crucial for every part of the air industry for determining policies, making decisions on investments, pricing, marketing, etc. This study analyses factors affecting the air cargo demand of the European Region (23 countries) on where no studies were found by making use of the two-step generalized method of moments (GMM). The effects of Total Airport Investments, Consumer Price Index, GDP Per Capita, Population, Foreign Trade Volume, Industrial Production Index, and Exchange Rate on Air Cargo Demand were examined with the data set covering the years between 2009-2018. The findings indicated that previous air cargo demand has explanatory power on current demand, and there was an inverse relationship between the change in the consumer price index and the amount of cargo. In addition, the panel regression estimator indicates a positive relationship between Foreign Trade and Industrial Production Index. The results show that price stability is of great importance not only from a macroeconomic perspective but microeconomically also.
航空货运需求评估对于航空业的每一个部门来说都是至关重要的,它可以决定政策、投资、定价、营销等。本研究利用两步广义矩量法(GMM),对欧洲地区(23个国家)未发现的航空货运需求影响因素进行分析。利用2009-2018年的数据集,研究了机场总投资、消费者价格指数、人均GDP、人口、对外贸易额、工业生产指数和汇率对航空货运需求的影响。研究发现,以往航空货运需求对现时需求有解释力,消费者物价指数变动与货运量呈负相关。此外,面板回归估计表明对外贸易与工业生产指数呈正相关。结果表明,价格稳定不仅从宏观经济角度,而且从微观经济角度都具有重要意义。

Presenteeism Among Ab-initio Pilots in Turkey 土耳其创业公司飞行员的出勤率
Pub Date : 2022-05-27 DOI: 10.30518/jav.1086578

In this study, we set out to estimate the prevalence of presenteeism and to define its possible association with organizational factors, committing errors and stress among ab-initio pilots. Presenteeism is a major safety-related issue and has been extensively studied in a variety of occupation groups. As a cross-sectional study, a self-administered questionnaire was used to collect the data from ab-initio pilots. The participants assessed themselves on the Stanford Presenteeism Scale (SPS-6). Correlation analysis was performed to explore the association between organizational factors and presenteeism. Based on the findings, the prevalence of presenteeism was 29.1 percent among the ab-initio pilots (N=175). Furthermore, there was a strong association between training-related stress (p< 0.01) and presenteeism. The student pilots with presenteeism were found to make mistakes during flight. Better and effective supervision for ab-initio pilots was associated with lower levels of presenteeism, highlighting the need for a supportive and comfortable atmosphere in the flight deck in which ab-initio pilots may feel comfortable. The findings presented here may facilitate improvements in the field of aviation safety.
在本研究中,我们着手估计出勤率,并定义其与组织因素、犯错误和压力之间的可能关联。出勤是一个与安全相关的主要问题,在各种职业群体中都得到了广泛的研究。作为一项横断面研究,采用自填问卷收集ab-initio飞行员的数据。参与者用斯坦福出勤率量表(SPS-6)对自己进行评估。通过相关分析探讨组织因素与出勤的关系。根据调查结果,ab-initio试点(N=175)的出勤率为29.1%。此外,训练相关压力与出勤率之间存在较强的相关性(p< 0.01)。出勤的学生飞行员在飞行过程中出现了错误。对新手飞行员更好和有效的监督与较低的出勤率有关,这突出了在飞行甲板上需要一个支持性和舒适的氛围,让新手飞行员感到舒适。本文提出的研究结果可促进航空安全领域的改进。
