When a fighter pilot makes a very quick turn, he experiences a centripetal acceleration. When this acceleration is greater than about 8 x g, the pilot will usually lose consciousness ("black out"). Consider a pilot flying at a speed of 900 m/s who wants to make a very sharp turn. What is the minimum radius of curvature he can take without blaking out?

Pilots of high-performance fighter planes can be subjected to large centripetal accelerations during high-speed turns. Because of these accelerations, the pilots are subjected to forces that can be much greater than their body weight, leading to an accumulation of blood in the abdomen and legs. As a result, the brain becomes starved for blood, and the pilot can lose consciousness ("black out"). The pilots wear "anti-G suits" to help keep the blood from draining out of the brain. To appreciate the forces that a fighter pilot must endure, consider the magnitude of the normal force that the pilot's seat exerts on him at the bottom of a dive. The plane is traveling at 219 m/s on a vertical circle of radius 674 m. Determine the ratio of the normal force to the magnitude of the pilot's weight. For comparison, note that black-out can occur for ratios as small as 2 if the pilot is not wearing an anti-G suit.
