Flight Test Instrumentation of the Push-Pull Effect on a CF-18 Aircraft

摘要

During high performance fighter aircraft manoeuvres, a fighter pilot may be exposed to a physiological phenomenon known as the "Push-Pull Effect" (reference (ref) [1]). This effect will alter the pilot's homeostasis whereas blood flow to the brain will be increased during low negative normal acceleration (-Gz) and suddenly decreased during positive normal acceleration (+Gz). It has been hypothesized that this effect can lessen the G-tolerance of the human body thereby making the subject more susceptible to G induced Loss of Consciousness (G-LOC) (refs [2],[3] and [4]). G-LOC is not a desirable state for a pilot in a high performance aircraft such as a CF-18.
