Book Description
In the modern world, travel and commerce within the aviation industry are major drivers of global economic growth. Nonetheless, a number of barriers stand in the way of the aviation industry's continued expansion and viability. The largest of these issues is the fuel usage in aircraft. An increase in fuel consumption results in a rise in operating costs and anthropogenic emissions. In order to evaluate aviation fuel consumption criteria, the author's goal in this book is to evolve, conceptualize, and develop a reliable Reduction in Aviation Fuel Consumption (RAFC) model. A thorough assessment of the literature served as the foundation for the development and conceptualization of the RAFC framework. Therefore, this book examined a mix of qualitative and quantitative methods to implement the methodology with primary and secondary data. It carried out analysis utilizing a variety of techniques, including regression analysis, factor analysis, structural equation modeling, and AHP-entropy. This combination guaranteed the study's adaptability, economy, and consistency. Future interest in minimizing fuel consumption and emissions and maximizing revenue under prevailing social, economic, political, environmental, and other restrictions might be stoked by knowledge of RAFC correlations with factors and sub-factors. Consequently, it will lead aviation toward a future that is both ecologically friendly and fuel-efficient. This book is a vital resource for academics, researchers, engineers, airline personnel, and decision-makers (governments and regulatory organizations) as it offers a thorough framework that gives an overall view of the aviation industry with regard to fuel usage.

Book Description
Increasing concern over the potential harmful effects of green house gas emissions from various sources has motivated the consideration of an aircraft certification standard as one way to reduce aircraft C02 emissions and mitigate aviation impacts on the climate. In order to develop a commercial aircraft certification standard, a fuel efficiency performance metric and the condition at which it is evaluated must be determined. The fuel efficiency metric form of interest to this research is fuel/range, where fuel and range can either be evaluated over the course of a reference mission or at a single, instantaneous point. A mission-based metric encompasses all phases of flight and is robust to changes in technology; however, definition of the reference mission requires many assumptions and is cumbersome for both manufacturers and regulators. An instantaneous metric based on fundamental aircraft parameters measures the fuel efficiency performance of the aircraft at a single point, greatly reducing the complexity of the standard and certification process; however, a single point might not be robust to future changes in aircraft technology. In this thesis, typical aircraft operations are assessed in order to develop evaluation assumptions for a mission-based metric, Block Fuel divided by Range (BF/R), and an instantaneous metric, incremental fuel burn per incremental distance (inverse Specific Air Range (1/SAR)). Operating patterns and fuel burn maps are used to demonstrate the importance of mission range on fleet fuel burn, and thus the importance of a properly defined range evaluation condition for BF/R. An evaluation condition of 40% of the range at Maximum Structural Payload (MSP) limited by Maximum Takeoff Weight (MTOW) is determined to be representative for the mission-based metric. A potential evaluation condition for 1/SAR is determined to be optimal speed and altitude for a representative mid-cruise weight defined by half of the difference between MTOW and Maximum Zero Fuel Weight (MZFW). To demonstrate suitability as a potential surrogate for BF/R, correlation of 1/SAR with BF/R is shown for the current fleet, and a case study of potential future aircraft technologies is presented to show the correlation of improvements in the 1/SAR metric with improvements in BF/R.

Book Description
This report provides results of work done to evaluate the calculation methodology used in generating aircraft emissions inventories. Results from the inventory calculation methodology are compared to actual fuel consumption data. Results are also presented that show the sensitivity of calculated emissions to aircraft payload factors. Comparisons of departures made, ground track miles flown and total fuel consumed by selected air carriers were made between U.S. Dept. of Transportation (DOT) Form 41 data reported for 1992 and results of simplified aircraft emissions inventory calculations. These comparisons provide an indication of the magnitude of error that may be present in aircraft emissions inventories. To determine some of the factors responsible for the errors quantified in the DOT Form 41 analysis, a comparative study of in-flight fuel flow data for a specific operator's 747-400 fleet was conducted. Fuel consumption differences between the studied aircraft and the inventory calculation results may be attributable to several factors. Among these are longer flight times, greater actual aircraft weight and performance deterioration effects for the in-service aircraft. Results of a parametric study on the variation in fuel use and NOx emissions as a function of aircraft payload for different aircraft types are also presented.Daggett, D. L. and Sutkus, D.
