B 777-200.
Please,
what do you insert, in the FMS, as cruise C.G, and why?
Thanks,to all, friends,
for explanations!!!

In the 200/300 (i.e without raked wingtips) there should be a de-fault cruise CG and I'm not aware of any reason to change it.

We get it from dispatch and it never matches the default value.

Greetings
Dispatch gets it from engineering, and engineering gets it from downlinked data where Cruise CG features, I believe that it is needed by the FMS to compute Max and Optimum, taking into account the drag generated by the stabilizer.

Are you guys eveny REMOTELY AWARE of the implications that the CG value has on takeoff,landing and most of all on cruise.....???
Omgg...

With such an introduction, King please go ahead I am dying to learn from you

much more about....
 

Thanks!!! all of you..but...
..i need moore about it!!!
we have a default number"14",and we leave that!!( the fwd limit)
"30",it could be better,and "44" much more!...but...
..how it works!?
Thanks!!!!

Are you guys talking about cruise CG, or T/Off CG?

In our ops, %mac T/O is entered in the T/O ref page for each departure. CRUISE C/G is a default value on the Vnav Cruise page. It is usually left as is, except on the 300ER and 200LR where it is changed to a different (fixed) value due to an Aerodynamic anomoly with the raked wingtips.

I've flown Boeings for a few companies, and have never had an operation where cruise CG was supplied as part of pre-deparure information.

There has been a discussion regards this in a previous thread guys.
