In summary, the maximum force a pilot can withstand is 7 times his weight, and the minimum radius of curvature that a pilot can tolerate at a speed of 250 m/s can be calculated using the formula v^2/R = 7g. With proper training and equipment, some pilots can withstand up to 11 g forces, but not everyone is genetically capable of handling such stress. The largest voluntarily experienced g force was close to 50 g's, resulting in detached retinas.

Here is a good one
The question reads
The max force a pilot can stand is about seven times his weight. What is the minimum radius of curvature that a jet plane's pilot, pulling out of a vertical dive, can tolerate at a speed of 250 m/s ?
Am I just crazy or is there not enuff info here to come up with a good answer.
Thanks tumbleweed

With training, and wearing an 'anti-g' suit, some pilots can withstand 11 'g' before passing out! (Hey, 7 'g' is good!)

In the Air Force, they now check applicants inherent genetic ability to withstand 'g' forces before training them up for the aircraft that pull 11 'g'. Only some people can ever cope with such stress.

Awesome!

The largest g force anyone has voluntarily experienced was close to 50 g's. The persons retinas were detached. fun! :rofl:
 

1. What is the maximum force a pilot can withstand during flight?

The maximum force a pilot can withstand during flight is known as the G-force. This force is measured in units of gravity (g) and is the acceleration that a pilot experiences during flight. The maximum G-force a pilot can withstand varies depending on the direction and duration of the force, but on average, pilots can withstand up to 9 g's before losing consciousness.

2. How does G-force affect a pilot's body?

G-force can have a significant impact on a pilot's body. As the force increases, blood is forced away from the brain and towards the feet, causing a decrease in cognitive function and vision impairment. It can also cause muscle cramps, difficulty breathing, and in extreme cases, loss of consciousness. Proper training and equipment can help pilots mitigate the effects of G-force.

3. What factors can affect a pilot's ability to withstand G-force?

There are several factors that can affect a pilot's ability to withstand G-force. These include age, physical fitness, and prior exposure to G-force. Younger pilots tend to have better G-force tolerance, and those who are physically fit are better equipped to handle the stress on their bodies. Pilots who have had previous exposure to G-force, such as military pilots, may also have a higher tolerance.

4. How is G-force measured during flight?

G-force is measured using an accelerometer, a device that measures acceleration. In aircraft, accelerometers are typically built into the instrument panel and display the G-force experienced by the aircraft. Pilots can also use G-suits, which are special suits that apply pressure to the pilot's body to help prevent blood from pooling in the lower extremities during high-G maneuvers.

5. Is there a limit to the maximum force a pilot can withstand?

Yes, there is a limit to the maximum force a pilot can withstand. The human body can only handle so much stress before it begins to shut down. While the average pilot can withstand up to 9 g's, some highly trained pilots have been able to withstand up to 12 g's for short periods. However, anything beyond this limit can be fatal, even with the use of a G-suit or other protective equipment.
