What is the primary function of the anti-G system in relation to bleed air?

The primary function of the anti-G system is to counteract the effects of high G-forces. In high-performance aircraft like the T-6A, pilots can experience significant G-forces during maneuvers, which can lead to G-induced Loss Of Consciousness (GLOC) if not managed properly. The anti-G system utilizes bleed air to inflate anti-G suits worn by the pilot, applying pressure to the body. This pressure helps to maintain blood circulation to the brain and vital organs, thus preventing the negative physiological effects caused by high G-forces.

The other options provided do not accurately describe the function of the anti-G system in relation to bleed air. While some might think about comfort or cockpit conditions, those are not the primary purpose of the anti-G system. The focus is specifically on maintaining pilot consciousness and functionality during extreme maneuvers through the use of the suit that operates with bleed air support.
