In this paper we present a novel approach to calculate Block Time and Fuel (BTF) consumed for an aircraft model during a flight. The BTF model computes the ground distance between the origin and destination airports, derives the flight’s cruise altitude and by integrating two institutional data sets calculates the duration and the fuel consumed for the whole of taxi-out, take-off, climb, cruise, descent, approach, landing and taxi-in phases. We use the French Association for Operational Research and Decision Support (ROADEF) 2009 Challenge flight rotation to sample our model. The statistical analysis of the results consisted of comparing BTF results for the block time and those from the ROADEF Challenge 2009 with the real ones retrieved from Flightaware® for the same origin and destination airports and aircraft model. Statistical results are reported for percentile and root mean square error, and we show that, using simple calculations, the BTF computational results for block time are in a lower percentile and have lower root mean square error than the block times used by the ROADEF 2009 Challenge. To compare the fuel consumed, we used the values for the real flights published in the literature review. We were able to verify a good fit between the BTF results and those values. Since the BTF model computational results are obtained within a few seconds, we also conclude that the BTF model is suited for flight planning and disruption recovery in commercial aviation.

计算飞机模型的阻塞时间和消耗的燃料

在本文中，我们提出了一种计算飞行期间飞机模型消耗的阻塞时间和燃料 (BTF) 的新方法。BTF 模型计算出发地和目的地机场之间的地面距离，推导出飞行的巡航高度，并通过整合两个机构数据集计算整个滑行、起飞、爬升、巡航、下降的持续时间和燃料消耗、进近、着陆和滑行阶段。我们使用法国运筹学与决策支持协会 (ROADEF) 2009 挑战飞行轮换来对我们的模型进行采样。结果的统计分析包括将块时间的 BTF 结果和 ROADEF Challenge 2009 的结果与从 Flightaware 检索到的真实结果进行比较®对于相同的始发地和目的地机场和飞机型号。报告了百分位数和均方根误差的统计结果，我们表明，使用简单的计算，块时间的 BTF 计算结果比 ROADEF 2009 挑战赛使用的块时间具有更低的百分位数和更低的均方根误差. 为了比较消耗的燃料，我们使用了文献综述中公布的实际航班值。我们能够验证 BTF 结果与这些值之间的良好拟合。由于 BTF 模型计算结果是在几秒钟内获得的，我们还得出结论，BTF 模型适用于商业航空中的飞行计划和中断恢复。
