[Human tolerance to landing impact (+Gz) in sitting position]

The study showed that macaca mulatta selected can be used as a substitute for human in studying tolerance to landing impact. Based on the data of the experiments, the revisional coefficient from macaca mulatta to humans was calculated, and curves of human tolerance to landing impact in sitting position were given. Tolerance limits for different injuries such as safe, slight injury, medium injury and serious injury are also given in this paper. The results might be useful for setting human tolerance standards to landing impact in sitting position.
