abstract

The purpose of this paper is to examine the effect of various aviation infrastructure dimensions over aviation fuel consumption reduction (AFCR) performance. This study is an effort that considers the role of dimensions collectively from all aspects belonging to aviation infrastructure. The relevance of dimensions and constructs for hypothesis development are based on extensive literature review. Exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed in the consecutive purification processes. Also, hypothesis testing was conducted using Structural Equation Modeling (SEM). A customized questionnaire was developed for collecting data from both kinds of respondents: Aviation industry experts and academic experts. Out of 382 approaches through mail survey, a total of 194 valid responses were collected. Analysis of the results shows the positive and significant impact of various factors such as: airport design, airspace management and air traffic control over the aviation fuel consumption reduction. Maximum importance is adjudged on air traffic control (ATC) and airspace route flexibility. The results of this study will encourage airlines and airport development authorities to increase their insight over aviation infrastructure, also to perform deeper analysis and find out precise values for real life implications.

A saving of 0.3 kg of aviation fuel can save almost a kg of CO2 emission, which in return also saves about 1.1 dollars (Tsai et al., 2014). Moreover, fuel reserves are depleting and there is dire need to look into the sustainability of the aviation industry. Supply-demand curves are showing an exponential gap. Tension between Middle East nations and huge demand of fuel from China is making the gap worse (Abdelghany et al., 2005). With this, airliners are confronting a challenge over maintaining their commercial viability, requiring a balance between increased fuel consumption and aircraft fuel cost. Furthermore, passengers mostly like to opt for airlines which have greater environmental consciousness (Hagmann et al., 2015). All these situations have encouraged airliners to explore efficient ways for aviation's fuel consumption reduction (AFCR).

5. Conclusion and suggestions

The contribution of this study can be listed as follows: 1) The study emphasizes on the importance of aviation infrastructure elements in fuel consumption. 2) The aviation infrastructure literature shows the scarcity of empirical research on the determinants of AFCR performance in the aviation sector. This study examined the viability of the model, and thus, the results of the present research contribute by filling the important gaps, by taking on a theory-based empirical investigation of the determinants of AFCR performance in the context of aviation infrastructure.
