NOTE: FIRST I've ASSUMED HERE THAT 7.91 times IS THE HORIZONTAL FORCE YOU ARE TALKING ABOUT (i.e. CENTRIFUGAL FORCE).
Here the force that trainee will experience will be centrifugal force acting radially outward and this is a type of pseudo force, because the body (i.e. jet fighter is revolving in a circle and ...
