Abstract

Current and future generation high performance fighter and attack aircrafts pose a significant risk of acceleration (+G_Z) induced loss of consciousness (G-LOC) for pilots. Head Level Blood Perfusion (HLBP) is one of the important physiological signals in the body, that gives information about pilots state. In this paper we investigate methods to extract useful information from HLBP data, that will help us to monitor pilot´s state and the level of the stress during flight
