What does the maximum G force recording include?

The maximum G force recording includes both positive and negative G forces because it represents the entire range of forces experienced by the aircraft and crew during maneuvers. Positive G forces occur when the aircraft is pulling up or climbing, resulting in increased pressure on the body due to acceleration. Conversely, negative G forces come into play during maneuvers such as diving or descending, where there’s a brief feeling of weightlessness or a reduction in the normal gravitational force.

Recording both types of G forces is crucial for understanding the stresses and strains placed on both the aircraft and its occupants during flight. This data helps pilots and engineers assess performance, safety, and define operational limits for future maneuvers. Hence, the inclusion of both positive and negative G forces provides a comprehensive overview of the aircraft's performance and the physical effects on the crew.
