While commercial flights exert only very minimal positive and negative G-forces on passengers, several orders of magnitude greater are the G-forces experienced by astronauts, fighter pilots and stunt pilots. What Happens to the Body With Extreme G-Forces? In general, most people will barely notice these forces. Put another way, the typical passenger will feel a maximum of up to 30% heavier or 30% lighter for brief moments depending on whether the aircraft is accelerating, decelerating, climbing, descending, or turning.

Rapid acceleration or deceleration from your current position increases or decreases the G-forces on your body, making you feel heavier or lighter, respectively.įor example, on the typical commercial flight and only during specific maneuvers, passengers typically experience no more than 1.3 Gs of force on their bodies and no less than 0.7 Gs. If you're sitting still reading this, your body is experiencing one G of force, which is the acceleration we experience due to gravity. G-force is a measure of acceleration or deceleration, which is the change in speed over time. Put simply, the 'G' in 'G-force' is an abbreviation for 'gravity.' However, many non-aviators certainly recognize it and use it themselves but might not necessarily know exactly what it is. The term 'G' or 'g-force' is most commonly used in the aviation field. But what exactly is a 'G,' and what are its effects on the human body? Here's everything you need to know about G-force, explained by our Las Vegas stunt flying experts. Have you ever ridden a roller coaster? Have you ever flown on a commercial jet? Have you ever taken a ride in a car? Have you ever stood still? If you answered yes to any of these questions, then you've experienced the effects of G forces on your body.
