gravity-induced loss of consciousnessAbbreviation: GLOC
The loss of consciousness due to positive gravity (G) forces. Certain aviation maneuvers produce increased downward force (that is, positive G) that is measured as a multiple of the gravitational constant. When these forces are of sufficient intensity, blood flow to the brain is diminished, which, if continued, leads to unconsciousness.
