基于航迹数据的油耗分析与研究

Analysis and research on fuel consumption based on trajectory data

随着航空运输业的快速发展,传统的基于飞行程序的燃油预测无法再精确计算飞机携带的燃油量,因此如何精确地进行燃油预测成为各大航空公司稳健发展的重要目标。为了更科学地解决燃油决策量问题,首先对航迹数据进行处理,以便在计算燃油消耗(简称油耗)中使用,然后依据飞机数据基础用户手册(BADA,user manual for the based of aircraft data)数据库的油耗计算方法,在假定各航段燃油消耗率恒定的情况下建立了飞机下降进近阶段的油耗模型,并通过对所得油耗数据进行分析,提出某一飞行阶段航空公司的燃油携带建议值,最后依据中国民用航空西南地区空中交通管理局云南分局提供的雷达航迹数据进行仿真验证,验证了所设计的油耗模型较之前的传统方法更准确可行。

With the rapid growth of the air transport industry,traditional flight procedure based fuel forecasting is no longer able to accurately calculate the amount of fuel carried by an aircraft,and therefore an accurate fuel forecast has become an important objective for the robust development of major airlines.In order to decide the quantity fuel consumption in a more scientific way,the trajectory data was firstly processed for use in the calculation of fuel consumption with the method based on the user manual for the BADA database,assuming a constant fuel consumption rate for each flight segment.The fuel consumption model for the descent and approach phase was then developed,and the analysis of the fuel consumption data was used to propose a recommended fuel carrying value for the airline for a particular flight phase.The proposed fuel consumption model was verified with the BADA database offered by Yunnan Sub-bureau,China Southwest Air Traffic Management Bureau.
