A Method of Constructing the Fuel Efficiency Model Based on Quadratic Polynomial Regression

This paper deeply analyzes the data which is closely related to the fuel efficiency in the production database of the airline transportation. It verifies that quadratic polynomial regression model is the best fitting fuel efficiency model after many experiments. It constructs the quadratic polynomial regression model of the fuel efficiency and derives the model's expression using the least square method. And, an example shows the rationality of the model, and better results of testing. Above all, it obtains the influences’ degree of energy-saving and emission-reducing measures in civil aviation to the fuel efficiency, and provides a good theoretical support for further optimization of energy-saving and emission-reducing measures.
