What are the potential effects of changes in flight direction or speed?

Changes in flight direction or speed can significantly alter the forces experienced by the body, which is where increased G-force comes into play. When an aircraft accelerates, decelerates, or maneuvers sharply, the occupants feel varying degrees of acceleration force, commonly referred to as G-forces.

For instance, during a rapid turn or when the aircraft climbs or descends quickly, the pilot and passengers experience a force that can multiply their body weight. This increase in G-force can lead to various physical effects, such as increased cardiovascular strain and potential for G-induced Loss Of Consciousness (GLOC) if the forces exceed the body's tolerance level.

Understanding the impact of G-forces is crucial for pilots and crew, as they need to be aware of how the physical stresses from flight maneuvers affect their ability to operate the aircraft safely.
