Abstract
Accurate assessment of aircraft fuel consumption is an important means for airlines to reduce flight costs and control fuel emissions. By analyzing the actual flight data of QAR, the functional relationship between the aerodynamic parameters in the fuel consumption model of the departure climb phase is fitted, and the crosswind is added to the fuel consumption assessment model. Based on the analysis of the departure training of Qingdao Airport, the fuel consumption model of the exit climbing stage was calculated using the improved fuel consumption model. The results showed that the calculation accuracy of the wind tunnel experiment was improved by 3.6%, and the theory of the fuel evaluation experiment considering the crosswind was considered. The accuracy of the model calculation and QAR data is 93.3%.
