The Blue Angels routinely endure 6 G maneuvers, and they don’t wear G suits. Military pilots are subjected to simulated G loads up to 8, and they learn how to minimize those loads to remain conscious and functioning. This aircraft is a trainer, and most likely equipped with G suit equipment to keep the neophytes from conking out during loops and steep banks. One F-4 pilot related his dogfight experience with a Mig, claiming he pulled to 12 Gs. I dunno, that might be Kentucky Windage.
