What does the anti-G system help to protect against during high-G maneuvers?

The anti-G system is designed specifically to combat the physiological effects that occur during high-G maneuvers, such as those experienced in high-speed or aerobatic flight. When an aircraft undergoes rapid acceleration or sharp turns, the increased gravitational forces can significantly impact a pilot's body. These forces can lead to G-induced Loss Of Consciousness (GLOC) due to reduced blood flow to the brain caused by the increased inertia pulling blood away from the upper body and head.

The anti-G system works by applying pressure to the pilot's body, particularly in the legs and abdomen, helping to maintain blood circulation to the brain and prevent the onset of these debilitating physiological effects. It plays a critical role in ensuring that pilots remain conscious and capable of controlling the aircraft, thereby enhancing safety and operational effectiveness during high-performance maneuvers.
