How? Their planes are designed to be flown while wearing g suits.
I could drone on about the friends I have who have flown with the Blues, show stories, combat stories, etc.
But I won’t.
Fact: they do Not wear g suits.
From the Blues official FAQ: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, so each pilot knows when one will be experiencing heavy gravitational forces. Anticipating the changes in gravitational forces allows the Blue Angels demonstration pilots to combat G-forces with muscle contractions. Additionally, G-suits would detrimentally impact flight safety.The Boeing F/A-18’s control stick is mounted between the pilot’s legs. The Blue Angels have a spring tensioned with 40 pounds of pressure installed on the control stick that gives the pilot a “false feel.” This allows the pilot minimal room for un-commanded 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-suit would interrupt this support and stability, causing un-commanded aircraft movement.
As for Gs...
Standard show the will push 8+ in some places, but not for long. Most riders get queesie around 3 or 4. They won’t generally exceed 7g with passengers in no 7, but they have been know to take no 7 up with a VIP for a full show.
