Statistical evaluation of fuel values

Abstract

Abstract Aviation emissions, domestic and international, account for approximately 2 % of total global CO2 emissions. Fuel consumption for a given route, excluding other factors such as wind, depends largely on the weight of the aircraft. To minimise fuel consumption, it is often most economical to carry only the minimum weight required for the sector. Within the framework of a dissertation, possibilities to reduce the final reserve fuel and thus the amount of fuel required are being researched and evaluated. This paper shows part of the results, as reliability and accuracy of flight planning and actual operations are a necessary basis for a possible reduction. The level of safety in aviation must always be taken into account. To prove this, fuel values are recorded and statistically evaluated, based on real flight and fuel data provided. Analysis, systematization and generalization were used to conduct the study. As a statistical background, extensive fuel data of an airline from a period of about five years were examined. The focus of this paper is on the results for taxi and trip fuel. The result shows that the current requirements for flight planning and the subsequent execution of flights are very reliable and highly accurate today. The results of the study can be used as a basis for a performance-based approach to reduce the final reserve fuel while maintaining the necessary safety level. Reducing the final reserve has a significant impact on reducing overall fuel consumption and emissions. Further research and studies are needed to determine performance indicators.
