What is anti g-suit?

An anti-g suit is a type of flight suit worn by pilots and other high-performance aircraft operators to help counteract the effects of high levels of acceleration (g-forces) on the human body. The anti-g suit is designed to prevent blood from pooling in the legs and abdomen, which can cause pilots to black out under high g-forces. The suit works by squeezing the legs and abdomen with air bladders or springs, which helps force blood up to the brain.

Anti-g suits are typically worn by pilots of high-speed aircraft such as fighter jets and are designed to be used in combination with other measures such as positive-pressure breathing systems to protect pilots from g-forces. The effectiveness of anti-g suits varies depending on the individual and the specific type of aircraft, but they are considered an essential piece of safety equipment for high-performance flight.
