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.
