What are the effects of positive g-forces during flight?

Positive g-forces during flight occur when an aircraft experiences acceleration in a direction that increases the gravitational forces acting on the occupants. This results in an increased sensation of weight for the pilot and passengers, effectively making them feel heavier.

As an aircraft maneuvers, such as during climbs or turns, the forces acting on it can exceed the force of gravity, leading to a heightened gravitational effect on individuals inside the aircraft. This phenomenon can be particularly pronounced in situations involving steep turns or rapid ascents, where the g-forces can amplify the weight felt by the body, leading to fatigue and potential physiological effects, such as g-induced loss of consciousness if the forces become too extreme.

In contrast to the chosen answer, the other options do not accurately reflect the effects of positive g-forces. Weightlessness would occur with negative g-forces or in free-fall scenarios, while decreased lift does not typically associate with positive g-forces, as these forces are generally not responsible for a decrease in lift but rather indicate increased load on the aircraft. Saying that g-forces have no significant effect overlooks the very real physical sensations and physiological responses experienced by individuals during flight under positive g-force conditions.
