This study proposes a novel procedure for estimating aircraft fuel burn during ground operations using aircraft trajectory data acquired from an airport surface surveillance system. A fundamental assumption employed throughout the study is that aircraft fuel burn on the ground depends on taxi phases and corresponding thrust settings. The computational process is split into three steps: (1) define a taxi phase for each data point by analyzing the trajectory data; (2) find the fuel flow index appropriate for each taxi phase of each engine type from the International Civil Aviation Organization (ICAO) Engine Emissions Databank which contains fuel flow indices for four flight status of every commercial engine; and (3) estimate the total fuel burn on the ground for each flight by multiplying the time duration at each taxi phase by the corresponding fuel flow rate.

Using 24-hour surface trajectory data collected from the Airport Surface Detection Equipment (ASDE) system at Seoul/Incheon International Airport, all flights operated on the day were analyzed applying this procedure. The results indicate that suggested taxi fuel burn rates are estimated to be about 17% lower than the ICAO values. The proposed procedure is expected to be used as an alternative method for ground fuel burn estimation.

这项研究提出了一种新颖的程序，该程序使用从机场地面监视系统获取的飞机轨迹数据估算地面运行期间的飞机燃油消耗。整个研究中使用的基本假设是，飞机在地面上燃烧的燃油取决于滑行阶段和相应的推力设置。计算过程分为三个步骤：（1）通过分析轨迹数据为每个数据点定义滑行相位；（2）从国际民航组织（ICAO）发动机排放数据库中找到适合每种发动机类型的每个滑行阶段的燃料流量指数，其中包含每个商用发动机四个飞行状态的燃料流量指数；

使用从首尔/仁川国际机场的机场表面检测设备（ASDE）系统收集的24小时表面轨迹数据，使用该程序对当天运营的所有航班进行了分析。结果表明，建议的出租车燃油燃烧率估计比ICAO值低约17％。预计拟议的程序将用作地面燃料燃烧估计的替代方法。
