Objective:This study was designed to identify factors affecting pilots" +Gz tolerance recovery from +Gz induced exhaustion.
Background: +Gz tolerance of pilots has been considered as a crucial factor to fly the modern high performance fighter aircrafts. However, the factors affecting pilots" G-tolerance recovery from +Gz induced exhaustion have not been examined in the acceleration research community.
Method: A centrifuge profile consisting of a high +Gz run for pilot"s exhaustion and a low +Gz run for pilot"s recovery and another high +Gz runs for pilot"s second exhaustion was designed. The subjects" +Gz tolerance recovery ratio was measured by ratio of second high +Gz run time to the first high +Gz run time. The subjects" +Gz tolerance recovery rate was measured by dividing the subjects" +Gz tolerance recovery ratio by the low +Gz run time. The subjects" G-tolerance recovery rate was analyzed with respect to the subjects" personal factors including subjects" anthropometric and physiologic characteristics, flight time, flying aircraft type and so on.
Results: The subjects" previous three-month flight hours (r =-0.336, p =0.039), sixmonth flight hours (r =-0.403, p =0.012) and one-year flight hours (r =-0.329, p = 0.044) correlated with the subjects" G-tolerance recovery rate.
Conclusion: The subjects" G-tolerance recovery rate is clearly related to the subjects" previous flight hours. However, the subjects" anthropometric and physiologic characteristics do not show any statistically significant correlation with the subjects" G-tolerance recovery rate.
Application: This research provides a safety critical insight to aviation community by identifying the factors to affect the gravity-induced loss of consciousness (GLOC) of pilots.
