A novel dataset based on satellite observations of aircraft positions was utilized to estimate normal accelerations of commercial aircraft during climb and descent legs. Further, these accelerations are used to simulate the effects on exposure to expiratory airborne contaminant inside commercial aircraft cabins. Compared to previous studies, which reported exposures more than twice due to high aircraft accelerations during the climb leg, the new findings suggest lower aircraft accelerations that result in exposures on par with steady level flights during climb and descent legs. The new findings place previous studies in context to be interpreted as extreme conditions only while they call for more detailed experimental investigations.

利用基于卫星对飞机位置的观测的新颖数据集来估计商用飞机在爬升和下降期间的正常加速度。此外，这些加速度用于模拟商用飞机机舱内暴露于呼气性空气污染物的影响。与先前的研究相比，以前的研究报告了由于爬升腿期间较高的飞机加速度而导致的暴露量是原来的两倍以上，而新发现表明，较低的飞机加速度导致在爬升和下降腿期间的暴露量与稳定水平的飞行相当。新发现仅在要求进行更详细的实验研究时才将先前的研究视为极端条件。
