What is a primary function of an anti-G suit?

The primary function of an anti-G suit is to counteract the physiological effects of acceleration forces experienced during high-speed maneuvers. When pilots encounter rapid changes in speed or direction, they can experience increased gravitational forces (G-forces) that may lead to a loss of consciousness or G-induced Loss Of Consciousness (GLOC). The anti-G suit is designed to apply pressure to the lower body, specifically the abdomen and legs, thereby preventing blood from pooling in these areas and maintaining adequate blood flow to the brain. This helps pilots remain conscious and operational under high G-load conditions, ensuring they can perform their duties effectively during flight.

Other options pertain to different aspects of flight equipment and safety, such as comfort, flotation, or communication, but they do not specifically address the primary purpose of the anti-G suit in counteracting the effects of acceleration.
