What is a correct statement about G-Induced Loss of Consciousness (G-LOC)?

The correct statement about G-Induced Loss of Consciousness (G-LOC) is that memory of G-LOC is frequently lost. This phenomenon occurs because, during G-LOC, the brain experiences reduced blood flow and oxygen supply due to high gravitational forces acting on the body. The brain’s ability to function properly is compromised, leading to a loss of consciousness. When an individual regains consciousness, it is common for them to have no recollection of the experience. This loss of memory is particularly relevant in aviation medicine, as understanding the implications of G-LOC can be crucial for pilot safety and operational readiness.

The other statements are less accurate in describing G-LOC. While some recovery can occur relatively quickly, it is not guaranteed to be within a specific time frame, as recovery can vary based on the individual and the severity of the G-forces experienced. G-LOC can occur suddenly and may not always be preceded by visual symptoms like grey-out, which refers to a visual impairment that can occur prior to losing consciousness but is not universally experienced. Additionally, blackout and G-LOC are not synonymous; blackout refers generally to loss of vision or perception, while G-LOC specifically pertains to loss of consciousness due to gravitational forces.
