Why G-Force is a Nightmare for Fighter Jet Pilots?

Why G-Force is a Nightmare for Fighter Jet Pilots. Becoming a military pilot is a terrifying physical and psychological challenge. Those expect or desire to fly fighter jets must prove incredible abilities. G-forces is one of the challenging and terrifying things for pilots.

That’s why pilots have to spend some time in a centrifuge to prove they can handle the pressure or G force.

What is G-Force?

G-force is a force acting on a body as a result of the acceleration of gravity. Pilots experience G-force in sharp turns. Faster and sharper the turn greater the G-force.

G-LOC

G LOC stands for Loss of Consciousness or gravitational loss of consciousness is where the blood from the person’s head is no longer in their head, and it pulled out to their lower body. Sometimes the G forces are so strong that pilots can lose consciousness. 

When the blood is heavy. It reaches the brain with difficulty. Since it has to fly against gravity but the brain and the eyes may need a constant supply of oxygen and sugar carried by the blood. If the supplies, cut off the person loses consciousness.

A normal human body can survive up to 5G but trained military pilots with a flying suit can hold on up to 9G.

On the ground, the human body experiences 1G, which is normal body weight, a combat pilot, and the other half experiences G many folds.

So if at 1G the bodyweight is 70 kilograms. At 9G. It is around 630 kilograms, that’s 9 times human normal body weight. The stress and strain, the body experiences at such high G are tremendous. At such high G, the body gets heavier so does the blood. When the blood is heavy. It reaches the brain with difficulty. Since it has to fly against gravity but the brain and the eyes may need a constant supply of oxygen and sugar carried by the blood. If the supplies, cut off the person loses consciousness.
