Consumers from India and The United States Have Differing Views of Flight Attendants
by Rian Mehta, Natasha Rao, Ethan Labonte, Stephen Rice, Deborah Carstens, Sierra Gaenicke
Abstract: Airlines are continuously working to enhance in-flight services to create a superior customer user experience. Flight attendants play an important role in the customers travel experiences. Flight attendants have the most interaction with the passengers, which directly impacts the passengers flight experience. The purpose of the present study is to assess the cultural differences of trust, if any, between Indians and US with respect to the age and gender of flight attendants. Analysing this aspect of trust is performed through manipulating the age and gender of the flight attendant. A cross cultural analysis comparing data from both Indian and US participants was conducted specifically asking participants to rate their levels of trust in flight attendants described as male or female and either 25 or 55 years of age. The results and the practical application of the study are discussed that resulted in useful
findings for the aviation industry

How Does Aviation Industry Measure Safety Performance? Current Practice and Limitations
by Steffen Kaspers, Nektarios Karanikas, Alfred Roelen, Selma Piric, Robert J. De Boer
Abstract: In this paper we present a review of existing aviation safety metrics and we lay the foundation for our four-years research project entitled Measuring Safety in Aviation Developing Metrics for Safety Management Systems. We reviewed state-of-the-art literature, relevant standards and regulations, and industry practice. We identified that the long-established view on safety as absence of losses has limited the measurement of safety performance to indicators of adverse events (e.g., accident and incident rates). However, taking into account the sparsity of incidents and accidents compared to the amount of aviation operations, and the recent shift from compliance to performance based approach to safety management, the exclusive use of outcomes metrics does not suffice to further improve safety and establish a proactive monitoring of safety performance. Although the academia and aviation industry have recognized the need to use activity indicators for evaluating how safety management processes perform, and various process metrics have been developed, those have not yet become part of safety performance assessment. This is partly attributed to the lack of empirical evidence about the relation between safety proxies and safety outcomes, and the diversity of safety models used to depict safety management processes (i.e. root-cause, epidemiological or systemic models). This, in turn, has resulted to the development of many safety process metrics, which, however, have not been thoroughly tested against the quality criteria referred in literature, such as validity, reliability and practicality.

Airport Management Perspectives on Aviation Biofuels: Drivers, Barriers, and Policy Requirements in the U.S. Pacific Northwest
by Daniel Mueller, Season Hoard, Paul Smith, Christina Sanders, Michael Gaffney
Abstract: This study explores perspectives of airport management on aviation biofuels in the Pacific Northwest of the United States by administering an online survey of airport managers in FAA certified airports in the region. Respondents provided their opinions on factors important for sustainable aviation fuel (SAF) development in the Pacific Northwest, including perceptions of various potential drivers and barriers to scale-up in the region. Most respondents indicated that policy certainty to attract capital, higher oil prices, and technology breakthroughs are required for a viable industry, and they also indicated that government intervention is important to ensure successful adoption and implementation. Respondents indicated that aviation biofuel tax credits, a system to issue and trade sustainable biofuel certificates, and fuel sustainability certification criteria are required policies/protocol to ensure viability. We suggest that a regional approach to examining barriers, drivers, and policy requirements provides more nuanced perspectives regarding key SAF development and scale-up issues.

Chinas airline industry deregulation: assessing the impact on the operational performance of dominant carriers
by Ioannis Koliousis
Abstract: This paper analyses the operational efficiency of the big three Chinese airline carriers post deregulation from the managerial perspective, using empirical data and by means of parametric methods in order to further understand the potential this market has for its dominant carriers. The analysis uses financial and operational data for the three dominant carriers in the Chinese airline industry and estimates the effect deregulation has had over a period from 19942012 to the dominant carriers. This analysis validates that the Chinese airline industry operational efficiency as measured by revenue and cash flow generation ability is positively associated with the load factor within a period that includes deregulatory initiatives. This finding highlights that the airlines have reacted positively post deregulation and have reasonably coped with competitive forces. Thus a further airline industry convergence is expected, on a global scale. This convergence will positively affect the Chinese airline industry, which in turn will benefit the passengers in terms of technology innovation, prices and welfare status.

Evaluating Human Error Data for Hazards in Air-Traffic Control and Deriving a Quantitative Safety Index
by Takeshi Matsuoka, Osamu Amai
Abstract: We developed an analysis method of hazards related to air-traffic control (ATC). We used mixing approach procedures such as required navigation performance, authorization required (RNP AR) and instrument landing system (ILS), as the test case. We carried out the hazard and operability (HAZOP) study and ATC real-time simulation experiments in the situation of the mixed operation for finding the hazards because we were not able to find them as the result of literature examination. We collected the data required for this analysis in the simulation experiment and selected HAZOP as the key assessment methodology.
The hazard analysis method developed enables to perform a quantitative HAZOP analysis. We quantified the likelihood of accidents and the ratios between the hazard severities at the development stage. Furthermore, we discussed a safety index based on the statistics of recent catastrophic air accidents around the world. A safety index matrix showed the regions of acceptable levels with mitigation by a quantitative index value.
