Why don't the pilots wear G-suits?
G-suits are designed with air bladders (pockets) that inflate and deflate to keep a pilot's blood from pooling in the pilots' legs while executing sharp, unpredicted combat maneuvers. Unlike combat flying, the Blue Angels demonstration pilots know the maneuvers they will fly prior to execution, each pilot knows when one will be pulling heavy gravitational forces. Knowing and anticipating the changes in gravitational forces allows the Blue Angels demonstration pilots to combat the G-forces with muscle contractions. In addition, the Boeing F/A-18's control stick is mounted between the pilot's legs. The Blue Angels have a spring tensioned with 35 pounds of pressure installed on the control stick that gives the pilot a "false feel." This allows the pilot minimal room for uncommanded movement. The pilots rest their right arms on their thighs for support and stability while flying. Therefore, inflating and deflating air bladders in a G-suits would interrupt this support and stability, causing uncommanded aircraft movement. In this case, Gsuits would detrimentally impact flight safety.
