Isn't 5 G's a lot? Where else could you pull that but in military aircraft?

5 G's is nothing, of course, in a Prowler its the end of the world :p wait till you start some ACM training, 5 G's, ha

all the civilian aerobatic planes can pull more than 5 G's, the Pitts can pull 9 and those guys aren't wearing G suits

pitts is +6, -3. An extra 300 on the other hand is +-10 :icon_smil . I haven't flown with a G suit before but doesn't it only give you 1 extra G? I would think the biggest difference between civilian akro and jets is how long the G's are sustained... jets have it way worse. except that you dont push a lot of negative! (ohhh my head :fight_125 )

Ah, the wisdom of a Prolwer stud.

Prowler NATOPS is actually 6.5 pos to 2.4 neg. (Lower under assymetric G-loads and at great speeds).

Yes, administratively limited to 4G's but that is because of FLE (fatigue life expenditure) and the need to make the jets last till 2010+. Being a HDLD (high demand, low density) assett means that they want to keep the jets flying. Every jet gets a monthly allocation of 4G hits. G stress is logarithmic. If 4G=1, then 5G=5, 6G=20, 7G=50. Numbers are illustrative not actual. So, if a jet has 20 4G hits for the month, one 6G hit in the break can use up that allocation and now it is 3 G limited and can only be used for airnav flights.

Now, if the ground, SAM, other aircraft is a threat, pull 6.5G. Heck, pull 7. With a 6.5G limit, the usual safety margin is 150%, so the wings should stay on till 10G. :D

EDIT: AHA!! The not-to-be-trusted wikipedia does say this:

"For instance, most civilian aircraft are capable of being stressed to 4.33 g"

"A typical person can handle about 5 g (50 m/s²) before this [blackout] occurs."

Any truth to this?

Wikipedia is edited by the general public. Not everything they say is 100% correct.

"Most civilian aircraft" means Cessna, Piper, etc. A Cessna 172 can go to like 3.5Gs or something, I can't remember.

G tolerance is person dependent. I know guys who start to black out at 3.

That is why I said it was "not-to-be-trusted," and why I asked specifically if there was "any truth to this?"

Obiously there were some truths, and half truths, and now the reality is plain for all to see.

FAS.org is another one that seems to get some of their data right most of the time.

I was just being sarcastic, hence the " :p "

I know about FLE, but didn't know about the point system, very interesting.

We already had the G-limit talk in class of FLE vs. SOP vs. NATOPS. And don't you worry, if I have to bend the wings to avoid a SAM, I plan on it.

Hell, even the Super Hornet birds are already under an FLE program. I thing they are limited to a 4 G break now or something. Some heresay I heard.

4G's for charlies?!?! nooooooooo!
4G's/350knots in the overhead & externals should be empty before hard manuevering, otherwise there are no restrictions on the A+/C/D ... and it seems only the Marine Corps is practicing this because I've seen some squid hornets in the last year coming in at the "speed of heat"

Say ..... by the way, you Marines .... do any of you know the name of a Marine General ... retired (or dead) now ..... who flew F-4's and F-18's ??? Vietnam era??? He was kind of notorious for doing a loop at an airshow (when the F-18 was "new" to the Marines) and crashing on the bottom side of it ---- he survived, broke his back, and I don't think it helped his career.

He had one tooth missing in front.

The reason I ask, is that he and I got spit out of a large 20+ plane gaggle/furball in Yuma once (when he first got the dogfight-capable F-4S) and he went on and on after we landed and debriefed as to how that was an "outstanding" fight and the "best fight I've ever had" .... blah, blah, blah .... Pretty good guy. Does anyone remember his name??? He looked and was built like your archtype USMC bulldog ......

From what I have gathered, the General you are talking about was CO of a squadron which had the hornet flying in the airshow. There was a pilot already scheduled for the demo, but being a COL at the time and owning the plane, he did the demo instead. Broke his back in the process and no longer flew afterwards. Incident sounds exactly like the one the Blue Angel crashed in less than a year ago. Remember to use your paddle switch (disengages G-Lim)if you don't think you're going to make it!

I love positive G's, I connot explain why I love them, I just do. Once I hit 5 G's, everything else just felt, ??. You guys know.
What civilian aircraft are you hitting 5 g's in?

That's him .... do you remember his last name, if he's no longer active?
