What is the Anti-Gravity System made of?

• A. A small electric motor
• B. Tubing and a valve which delivers regulated air pressure to the pilot's anti-G suit
• C. An electronic control module
• D. A liquid cooling loop

Answer: (B)

The Anti-Gravity System works as a pneumatic system that inflates the pilot’s anti-G suit to counter high-G forces. Its essential components are the tubing that carries compressed air and a valve/regulator assembly that delivers and maintains the correct air pressure in the suit’s bladders. When the bladders inflate, they apply external pressure to the legs and abdomen, helping keep blood in the torso and brain during tight maneuvers. This is why the option describing tubing and a valve delivering regulated air pressure to the suit is the best choice. The other items aren’t the system itself: a small electric motor isn’t the inflation source, an electronic control module may monitor or coordinate but doesn’t inflate, and a liquid cooling loop serves a different purpose.
