Fuel consumption interval estimation method for aircraft flight segment based on qar data

Abstract

The invention provides an aircraft route segment fuel consumption range estimation method based on QAR data. The aircraft route segment fuel consumption range estimation method based on the QAR data comprises the steps that the QAR data are classified according to aircraft models and route segments to obtain QAR data samples of specific route segments of specific aircraft models; fuel consumption data are extracted from the QAR data samples and calculated, so that fuel consumption samples of the specific route segments of the specific aircraft models are composed; the mean value and standard deviation of the fuel consumption samples are calculated; a normality test is conducted on the fuel consumption samples; the minimum sample size is calculated with a given significance level and given estimated accuracy; the minimum sample size is checked; fuel consumption range estimation of the specific route segments of the specific aircraft models is conducted. According to the aircraft route segment fuel consumption range estimation method, the QAR data are classified according to the aircraft models and the route segments to conduct fuel consumption range estimation of the specific route segments of the specific aircraft models, and therefore the purpose of determining and checking the minimum sample size in the process of conducting fuel consumption range estimation of the specific route segments of the specific aircraft models through the QAR data is achieved under the circumstance that the sample size of the QAR data is limited.

Description

technical field [0001] The invention belongs to the technical field of civil aviation transportation, and in particular relates to a QAR data-based method for estimating the fuel consumption interval of an aircraft segment. Background technique [0002] In recent years, with the rapid development of my country's civil aviation transportation industry, the consumption of aviation fuel has continued to increase. According to statistics, the cost of aviation fuel has accounted for more than 1 / 3 of the total operating costs of airlines. At the same time, the emphasis on energy conservation and emission reduction at home and abroad is also increasing, so airlines are currently facing the pressure of energy conservation and emission reduction. Reducing jet fuel consumption is one of the important measures to improve efficiency, save energy and reduce emissions, which requires airlines to estimate jet fuel consumption more accurately.
