A positive Gz force is applied from which direction toward which?

A positive Gz force is defined as the acceleration experienced in the vertical direction, specifically from the head towards the feet of the body. This force can be experienced during maneuvers in an aircraft, particularly during high-speed turns or dives, where the pilot feels an increased gravitational pull pressing downwards.

In this context, the term "positive" signifies that the force is directed in the same way as the acceleration due to gravity, enhancing the downward sensation on the body’s axis from the head to the feet. It’s important to understand that this vertical force can lead to physiological effects, such as increased cardiac workload or even G-induced loss of consciousness if the forces exceed what the body can tolerate.

Other directional forces, such as left to right or front to back, represent lateral or longitudinal G forces, which do not signify positive Gz effects and would be associated with different experiences and physiological responses.
