## What is extreme G-force?

High-G training is done by aviators and astronauts who are subject to high levels of acceleration (‘G’). It is designed to prevent a g-induced loss of consciousness (G-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.

## Which is the most hazardous G-force?

There are isolated incidents of humans surviving abnormally high G-forces, most notably the Air Force officer John Stapp, who demonstrated a human can withstand 46.2 G’s. The experiment only went on a few seconds, but for an instant, his body had weighed over 7,700 pounds, according to NOVA.

How many G’s can you survive?

9 g’s
Normal humans can withstand no more than 9 g’s, and even that for only a few seconds. When undergoing an acceleration of 9 g’s, your body feels nine times heavier than usual, blood rushes to the feet, and the heart can’t pump hard enough to bring this heavier blood to the brain.

### What is the most G-force ever?

TIL the highest recorded g-force ever survived is 214 g’s, more than 8 times lethal levels.

### How many G forces do fighter pilots feel?

Fighter pilots can handle greater head-to-toe G forces—up to 8 or 9 G’s—and for longer periods by wearing anti-G suits. These specialized outfits use air bladders to constrict the legs and abdomen during high G’s to keep blood in the upper body.

How many G-forces do astronauts feel?

Astronauts normally experience a maximum g-force of around 3gs during a rocket launch. This is equivalent to three times the force of gravity humans are normally exposed to when on Earth but is survivable for the passengers. Astronauts are trained in high g-force, wear g-suits and must be correctly prepared.

#### What g-force is fatal?

Changes in speed are expressed in multiples of gravitational acceleration, or ‘G’. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.

#### How fast is 1 g in mph?

22 mph
For example: An acceleration of 1 g equates to a rate of change in velocity of approximately 35 kilometres per hour (22 mph) for each second that elapses.
