Review of Civil Aircraft Fuel Consumption and Fuel Savings

The aviation industry is one of the top ten greenhouse gas emitters worldwide. Aviation fuel, as a non-renewable disposable energy source, is costly and emits a large amount of pollutants during the combustion process. Reducing fuel consumption during flights is an important research focus in the aviation industry. To achieve fuel efficiency and emission reduction in the aviation industry, one aspect is the accurate prediction of fuel consumption, estimating the required fuel for route flights to minimize unnecessary fuel consumption. Another aspect is to study the impact of various factors on fuel consumption based on the aircraft's performance and external environmental factors during different flight phases. This allows for the development of targeted strategies to reduce fuel consumption and emissions. This article aims to achieve fuel efficiency in aircraft by analyzing the current status of fuel consumption models, summarizing existing fuel consumption prediction methods, and identifying future trends in fuel consumption model development. It provides an overview of fuel consumption strategies for different flight phases and summarizes fuel-saving measures for each phase, offering academic support for fuel efficiency and carbon reduction in the aviation industry.
