I've flown many times with AirCombat USA 1v1 in SIA-Marchetti Italian dog-fighters. RL planes with little razor wings and high-perfomance engines. Yes, (per somebodys comment above) you DO strap in as tight as you can pull the 5-point military harness over your parachute straps. VERY constrictive, but holds you in place when inverted and you push the stick forward (quite a rush).
As per head movement under G forces? IMHO? Ain't much differance than what you see on an AH screen.. perhapds slightly deeper "sit" under +G?
Side to side? (as someone said) didn't seem to be a real "head-banger" extreme, even in a unexpected snap-roll,,? Again, my opinion from watching my own "replay" films after ACUSA engagments.
Bear in mind that you're wearing a military helmet, also strapped on TIGHT, and the lower ear area of the helmet will squash down on your shoulder tops under heavy G, and somewhat actually SUPPORT your head..
Playing aerial lazer tag in real dogfighter crotch-rockets, is pretty intense. In a 1v1 both about the same skill level? It always comes out as to WHOM CAN TOLLERATE THE MOST, SUSTAINED G's.
I've won more engagements by being able to out-G the next guy, than by sheer skill. You know the gig is up, when you see the other planes bubble canopy splattered with breakfast, and the military IP wiping it down.
You both crawl out back at base, drenching wet from squeezed sweat, and feel like you were beaten up by a street gang.
Kinda goes like this for real..
4? 5? 6 sustained G's? Most non-military pros' (armchair aces) can take about 10 or 15 seconds of +5 sustained G's. I've spoken with the ex-military fighter jocks who ride with us about this. They say it's a practiced, "accumlative" resistance thing. Ie: The more often you fly under heavy G's, the more you can tolerate.
About to lock onto the enemy, after a 15 minute loop-dee-loop special??
Pull, pull, pull the stick a little more.. the big HUD glass-sight is only a few degrees from the tail of your adversary.. Take slack out of trigger.
You squash down in the seat,, and you feel the skin around your cheeks start to sag.. +4 Gs?
Pull the stick a little more, now on +5g's! Your lower jaw is pulled down, mouth open, helmet now squashed down on shoulder tops. You lift shoulders trying to relieve some of the helmet pressure, neck is locked straight up n' down, you can NOT look UP anymore, because neck muscles can not support the pressure of skull & helmet anymore.
(to see what it feels like? sit in hi-back chair at home. lean head up and over backwards, look at ceiling, as in the "Up" view in AH. Have somebody get behind the chair, and grab you around the top forehead and pull back with all their body weight. NOW.. try and move your head down).
THAT, is +6gs wearing a helmet.
Soooo.. the plane ahead of you is now only a measly 4 degrees above the HUD pipper!
Pull back a sk'osh more.. You start to see little yellow stars, like when you rub your eyes too hard?.. The roar of that wide opened engine gets softer, and you can hardly hear it anymore.. Things are getting real quiet.
You just move your eyes up to look for the HUD site and the enemy plane is ALMOST THERE.. another 1 degree!!
Pull back one last little yank..
Your eyes only see in the middle.. the edges are dark and fuzzy (just like in the AH SIM!) ..
6 and 1/2 G's..
The little yellow stars fill your vision, and turn to foggy white.. the last thing you actually "feel" is the burbbling of the Marchettis' little razor wings entering the pre-high-speed-stall "buffet".. you feel it in the stick, just before you go to sleep.
The plane departs flight, goes ballistic, and does a full snap-roll before the ex-military fighter instructor pilot takes control..
You wake up about 4 seconds after G's are released, and you hear this on the radio..
"GUNS, GUNS, GUNS, Good kill, breaking off left.." (you loose)
Your neck & shoulders are KILLING YOU, sweat is dripping out the helmet and down your face like a water faucet, and you lost the first engagment.
Only 6 more to go, and you'll feel like a new man! (or woman!)
AHahahaa!!
My 2 cents..
