摘要：The cost of fuel and its availability are among the most major concerns for aircrafts and the aviation industry overall. Environmental difficulties with chemical pollutant emissions emitted by aviation machines are also connected to fuel consumption. As a result, it is crucial to examine factors that affect the overall fuel usage and consumption in the airport-based aviation industry. Several variables were investigated related to the total fuel consumed, such as dry operating weight (DOW) (KG), zero-fuel weight (ZFW), take-off weight (TOW), air distance (AIR DIST) (KM), and ground distance (GDN DIST). Analysis of the correlation between total fuel consumed as well as the extra fuel and selected variables was conducted. The results showed that the most positively associated factors with the total used fuel were the air distance (r<sup>2</sup> = 0.86, <i>p</i> < 0.01), ground distance (r<sup>2</sup> = 0.78, <i>p</i> < 0.01), TOW (r<sup>2</sup> = 0.68, <i>p</i> < 0.01), and flight time (r<sup>2</sup> = 0.68, <i>p</i> < 0.01). There was also a strong positive association between the average fuel flow (FF) and actual TOW (r<sup>2</sup> = 0.74, <i>p</i> < 0.01) as well as ZFW (r<sup>2</sup> = 0.61, <i>p</i> < 0.01). The generalized linear model (GLM) was utilized to assess the predictions of total energy usage after evaluating important outliers, stability of the homogeneity of variance, and the normalization of the parameter estimation. The results of multiple linear regression revealed that the most significant predictors of the total consumed fuel were the actual ZFW (<i>p</i> < 0.01), actual TOW (<i>p</i> < 0.01), and actual average FF (<i>p</i> < 0.05). The results interestingly confirmed that wind speed has some consequences and effects on arrival fuel usage. The result reflects that thermal and hydrodynamic economies impact on the flying fuel economy. The research has various implications for both scholars and practitioners of aviation industry.
