The correct answer is positive Gz, which refers to the acceleration force felt in the head-to-foot direction in a vertical plane. When an aircraft maneuvers, particularly during rapid ascents or turns, the forces generated can push the body into the seat. This force, often referred to as "G-forces," is associated with the effects of gravity in that direction.

In this context, "positive" indicates that the force is acting in the direction of the gravitational pull, effectively increasing the weight sensation or pressure felt by the body as it is pressed into the seat. It's important to note that positive Gz is commonly experienced in situations such as quick climbs or banking turns in an aircraft, reinforcing the feeling of being pressed downward due to the acceleration in the upward direction.

The other choices relate to different orientations or effects of gravitational forces. Negative Gy generally suggests an upward acceleration, while negative Gz would imply a lighter feeling or being pulled upward away from the seat. Positive Gy relates to movements that create a downward force or pull, but in the scenario given, the focus is on being pressed down, making positive Gz the appropriate term to describe that experience.
