Which statement about G-LOC is true?

The statement that G-LOC frequently results in memory loss is accurate because G-LOC, or G-induced Loss Of Consciousness, occurs when the body experiences high G-forces that compromise blood flow to the brain, leading to a temporary loss of consciousness. During an episode of G-LOC, the brain may not record memories properly or at all, resulting in significant memory loss concerning the events leading up to and during the G-LOC event.

This phenomenon is crucial for pilots and aircrew to understand, as memory lapse can compromise situational awareness and the ability to respond effectively in high-stress environments. Recognizing the effects of G-LOC on cognitive functions is essential for maintaining operational safety in aviation.

The other choices do not accurately describe G-LOC. It is unpredictable due to the variables involved in G-forces and individual tolerance; there is often a recovery time needed post-episode for cognitive functions to return to normal; and G-LOC does not stem from hyperoxia—instead, it typically results from hypoxia due to reduced blood flow to the brain.
