What is G-Force?

The Impact on Pilots and Passengers

G-Force, or gravitational force, measures acceleration felt as weight that affects aircraft, pilots, and passengers during flight manoeuvres.

G-Force stands for gravitational force; in aviation, it refers to the force of acceleration or deceleration relative to free-fall. This force is experienced as a weight on the body, and it's particularly noticeable in aviation manoeuvres that involve rapid changes in speed or direction, such as takeoffs, landings, and tight turns.

Effects on the Human Body: The human body can experience various effects under different G-Forces. Blood may struggle to reach the brain at high G-Forces, leading to vision impairment or even loss of consciousness (known as G-LOC, G-induced Loss Of Consciousness). Conversely, negative G-Forces, experienced in downward acceleration, can cause blood to rush to the head, which is also dangerous.

Importance in Aircraft Design: Aircraft are designed to withstand certain levels of G-Force, ensuring structural integrity and safety. Both military and civilian aircraft undergo rigorous testing to determine their G-Force limits.

G-Force is a critical consideration in aviation, affecting not just the physical design of the aircraft but also the training and safety protocols for pilots and the overall flight experience for passengers.
