G-loading on a heavy jet

Just curious, what can something along the lines of a 767 safely endure in terms of g-loading? Thanks

By design, the minimum standards, 2.5 is design load, 3.75 is ultimate load, and negative 1g. Some will exceed those by a wide margin, others (like the 777 in the video on youtube) will pretty much break on schedule.

I didn't realize it was so little, we usually pull 3-4 G's in the pattern lol
 
I had to explain to an F16 guy once why rolling 90 degrees and loading 4gs wasn't an acceptable crosswind pattern turn in a Seminole.

I have had two of those, both came in for their multi-ATP checkride. One from a F16, the other from a P3.

Ahh man, the good ole' days..

"Yeh, that was a really nice landing.. but.. this is Fulton County, no the USS Independence.."

Dude, those military guys were nuts.. Some of them would come in on flight 1 and not even know how to turn the thing on, they'd have a fit in the bird.. Send them home for lunch, they'd be back for flight 2 like it was the only airplane they had ever flown.. I love flying with them.. :)
 
Like Tram said, the cool thing about Military guys is you'd ask them to memorize something and you'd go out and fly two hours with another stud and when you came back not only would they have memorized what you asked, but also every other thing in the book.

It was very different flying with fighter guys who were used to doing everything themselves (but had a nasty habit of throwing the plane around a bit) and heavy transport/refuel guys who were used to working with a crew of 5.

That said I can't think of one of Military student I didn't enjoy training.
 
Don't mean to hi-jack the thread, but the tower still calls me out to other traffic as 'the Cessna 182 on a tight downwind!!!'

:D

I enjoyed and learned a good bit from all but one of them..

Had a P-3 guy.. Even the examiner had a hard time believing this guy actually flew in the military.. Complete moron..

Couldn't work the radios..
Couldn't fly the plane..
Couldn't this.
Couldn't that..
 
The plane will take more than the passengers will.

I've heard that said a few times from various people. Absolutely stupid and deadly remark.

Each person that said that to me was immediately written off the list of someone who I would take any advice from.
 
I do think that is a generalization. I snagged a ride in a T38 and was SOMEWHAT aware of what was going on through about 6.5. I know that there is no way a Cessna's wings are going to stay on at anywhere NEAR that number.

Like anything else, some guys rock, some guys suck.

Given that the low end Cessnas have a load factor limit of 4.4 in the utility category and an ultimate load factor of 50% greater than that, the aircraft should withstand about 6.6g's before the wing starts failing. (for 3 s anyway.)

And if you're lightly loaded, possibly more than that....the wings feel load, not load factor.

You're assuming it's a utility Cessna AND you're assuming it's factory new. I somehow doubt material stress testing is done every 100 hour.

On paper sure, but somehow I doubt that a 1975 Flight School Cessna is going to hold together if you load the wings to 8.8 gs.

Rumor has it, Trogdor said it once.. ;)
