Study on Aviation Fuel Efficiency Evaluation System Based on QAR Data Analysis

Recently, airlines mainly rely on QAR (Quick access Record) data to evaluate the combustion efficiency. Due to the multi-level relation of combustion efficiency, the index system is complicated. Meanwhile, some uncontrollable factors could greatly affect the fuel combustion evaluation, such as, payload changes of airplane. It is urgent to establish a relatively intuitive, simplified and reasonable combustion efficiency evaluation system based on the QAR data, to reflect the management ability of energy conservation and emission reduction of airlines. This paper focuses on the superiority of total combustion index use. By the method of correction payload comparison analysis, it could avoid the abnormally jump of combustion efficiency in the airlines operation and contribute to establish the relative combustion evaluation system. Due to the data accuracy, it could reflect the refinement and volatility process of the fuel cost of the airlines in the COVID-19 period. There is significant reference for the airlines’ cost evaluation and control in the future.
