CG Envelope Chart

Somewhere on this forum is a post that includes a chart showing the CG envelope as a function of weight.

I've been searching for it and I can't find it. Does anyone recall where to find it?

Thanks.

Do you mean this one? It can be found in AMM 07-11.

That'a similar, but not the one I'm talking about. The one I saw was for flight, and had a line that demarcated the regime where procedures for a low weight, aft-CG takeoff procedure needed to be followed. There was also a marking showing that the min CG for flight varied by weight.

Something along the lines of this, it's from the AFM. There are a lot of CG graphs, I can send them to you via mail.

I'd say it's legally wiser to abstain from posting Boeing's copyrighted material.

😅I learned that lesson, I posted or requested things on this forum that infringed copyrights (those posts where deleted accordingly). I meant more as in pictures, I could also post them here but there are a lot of CG charts in the AFM...

That is the chart I was looking for. It's here elsewhere on the forum, but difficult to search for. I don't need anything else, thanks.

Surely. I was just making sure we're not getting anybody, remotely, into trouble. I understand getting hold of manuals and material is deeply frustrating in our hobby and luckily, B747-400 is not that notorious in such essence. In that occasions which referral to documents are in dire need, I usually try to reference online public files and pages that are already available through other websites; just to be safe.

Copyright allows for a certain percentage to be shared so long as the whole document is not provided. For example 4 pages of a flight manual may be reproduced but 6 may not depending on number of pages in whole manual.
I learned about this when studying for my zoo keeper certificate as several younger students kept using whole chunks of docos as examples which they were told they could not do.

A couple of charts should be OK, so long as acknowledgement of origin/author is given.
