There is a lot of evidence regarding air flight accidents caused by human error, especially air traffic controllers (ATC). On the other hand, the principle of work safety through safety performance can help organizations reduce the number of work accidents and create zero accidents in the aviation industry. This research aims to analyze the effect of leadership on safety culture and safety performance by investigating the mediating role of Safety Based Dynamic Uncertainty Reduction (SDUR) as an integral aspect in safety research. A total of 214 respondents were involved in this research. The analysis technique used in this study is Partial Least Square-Structural Equation Modeling (PLS-SEM). The results showed significant effects of leadership on safety culture and safety performance. The mediating analysis also reveals the significant effects of SDUR in strengthening the impact of leadership to safety performance. As implications, SDUR can be considered as an effective strategy in improving Safety Performance in the workplace.

This research aims to account for the cost of quality through lean and agile operations strategies with empirical evidence from the Aviation industry in the UAE. The cost of quality improvement through lean and agile strategies was not researched enough in the aviation industry. This research will contribute with great knowledge in the aviation industry. The research design used a descriptive, explanatory, causal, and analytical method. A cluster sampling technique was used with a valid sample size of 251 respondents for analysis by multiple regression using ANOVA. Results indicated the significant relationship between lean and agile operations strategies on the cost of quality. There is a direct positive significant relationship between the cost of quality and SC strategies to get quality products cost-effectively. This research was limited to the lean and agile strategies and cost of quality analysis in the aviation industry in one city in the UAE. In contrast, it requires detailed research to explore other cities and assess the aviation industry's challenges while implementing lean and agile strategies. Cost elimination with high-quality production is fundamental for a successful business; lean and agile operations can reduce airline companies' costs and propose the criteria to adopt the strategic implementation efficiently.

Customer loyalty plays an important role for the success of aviation companies. Most airlines companies rec-ognized that a frequent flyer is about 10 times more valuable than an associational flyer. As a result, it is essen-tial to evaluate determinants of Vietnamese frequent flyers related to loyalty toward American-based airlines like Delta Air Lines. The customer loyalty was impacted by service quality, brand image, perceived value, pric-ing policy, and customer satisfaction. A sample of 300 Vietnamese frequent flyers of Delta Air Lines was col-lected for this study. The primary data was analyzed with SPSS and AMOS. The results indicate that service quality had no impact on customer loyalty of Delta Air Lines frequent flyers in Vietnam while the rest variables maintained some effects. There were several limitations of this study such as sampling, questionnaires design, and data collection. This research also contributed implications for further studies about customer loyalty in aviation industry.

This paper presents an investigation on existing challenges in developing aviation industry in Iran. The proposed study designs and distributes a questionnaire among all specialists who are involved with design, production and distribution of aviation industry in Iran. Our interview has revealed that there were approximately 200 potential experts as population of our survey. The designed questionnaire consists of six parts in Likert scale in terms of linguistic terms. All six parts of the survey was designed based on four segments of aviation industry in Iran. Based on the results of this survey, appropriate structure for the legislative, availability of sufficient funds for purchasing private planes, public access to the airports and airport services and availability of supply chain management and technical service centers are the most important challenges in this industry. In addition, availability of various infrastructures such as runways, hangars and maintenance centers to access the industrial towns and insufficient support from relevant organizations such as the ministry of commerce, industry and mining, civil aviation organization and other organizations in the manufacturing and aircraft are among other most important challenges in developing this industry in Iran.
