TRIZ tool is used for conceptual design and layout of the novel ascending and descending runway model for the effective utilization
of short length airports. Handling bigger aircrafts at smaller airports become the necessity for economic consideration and
for the benefit of vast airliners and the aspiring air travelers of the region. The authors’ p...

... But, how much or whether will it save fuel doesn't entirely depend on the cross runway. Rao et al. (2009) found runway slopes can decrease runway length by 15e20% then level runways. Runway length is considered to be an important parameter for deciding the aircraft size that will be in use (Hamzah and Adisasmita, 2015). ...
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.
With the projected air traffic growth, aviation fuel needs will grow by 3% globally per year. Considering this, aviation industry has set ambitious goals to enhance its fuel efficiency. This study presents an integrated framework for aviation fuel consumption reduction, which will also limit its CO2 emissions. Further, this research aims to categorize influential factors and examine their relative importance for fuel-efficient aviation. This study’s theoretical framework combines and reconciles eight major areas: alternative jet fuels, aviation infrastructure, aircraft operations, socio-ecopolitical environment, aircraft design, technology, environmental uncertainty, and strategic changes. In all, 37 sub-factors were identified. The priority ratings of these sub-factors with respect to ‘aviation fuel consumption reduction’ objective is measured by hybrid analytical hierarchy process-entropy method, using pair-wise comparison matrices. The findings attributed the highest importance to ‘technological innovations’, followed by ‘aircraft design’ and ‘aircraft operations’ for saving aviation fuel. Based on the obtained ranking ‘engine design’, ‘laminar flow technology’, and ‘air traffic management technology’ emerged as the three most important sub-factors. The robustness of priority rankings has been tested using sensitivity analysis. This study shows the path for continuous improvement in aviation fuel efficiency by directing efforts and investments on highly important factors.
Aviation is one of the fastest mode of transportation in the world, and demand for air transportation is growing continuously. The past oil crises, volatile fuel prices, depleting fuel stocks, and increasing environmental concerns have drawn the significant attention of aviation industry towards the need for judicious use of aviation fuel. Thus, economic and environmental sustainability concerns have led to dramatic progress in aviation fuel efficiency improvements in the past decades. However, significant efforts to improve the fuel efficiency through more advanced designs, techniques, and strategies will remain a priority. This article provides an overview of the challenging issues, accomplishments, and opportunities in relation to the aviation industry, focusing on aviation fuel consumption. This article offers insights for the aviation industry, that is, aircraft manufacturers and airlines to move toward more fuel-efficient options in future.
