Correct Answer : Keeping the head in the upright position
Explanation : Keeping the head always in an upright position is not an option for pilots since the pilot will lose situational awareness if he does so. The pilot will feel the inertial forces irrespective of his head position. By reducing the moment of inertia we can reduce the inertial torques experienced. Reducing weight and positioning the CG of the helmet with the pivoting point of head ensures that there are minimal out of balance moments.
