What is the purpose of the Ant-Gravity (anti-g) suit?

• A. It cools the aircrew during high-G flights.
• B. It inflates bladders to apply pressure on the body as G-forces increase to restrict downward blood flow and reduce blackout.
• C. It stores emergency oxygen for high altitude flight.
• D. It acts as a ballistic shield for cockpit impacts.

Answer: (B)

When pilots pull high Gs, blood tends to pool in the legs and abdomen, which can reduce blood flow to the brain and cause blackout or G-LOC. The anti-G suit solves this by inflating bladders in the legs and abdomen as G increases, squeezing the body from the outside. This external pressure helps keep blood in the upper body, sustaining cerebral perfusion and reducing the chance of losing consciousness during tight maneuvers. It’s not about cooling, storing emergency oxygen, or providing ballistic protection—the suit’s primary job is to counteract the pooling effect of high Gs by pressure, keeping the pilot’s brain supplied with blood.
