What effect do negative g-forces have during flight?

Negative g-forces during flight occur when an aircraft experiences rapid downward acceleration, which can create a sensation of weightlessness for the pilot and passengers. This is because, under these conditions, the force acting on the body is less than the normal gravitational force that is felt during standard flight. When the g-forces are negative, it can feel as though the body is not being pulled down by gravity, resulting in a brief experience akin to floating or weightlessness.

This phenomenon is particularly noted in maneuvers such as steep climbs followed by rapid descents or in certain aerobatic maneuvers where negative g-forces are pronounced. Understanding this sensation is crucial for pilots, as it can impact their physical response and control during various phases of flight. Other choices may involve aspects of aircraft dynamics or operations, but they do not accurately describe the specific experience associated with negative g-forces in flight.
