At my company in other aircraft AOMs, in the section on Engine Start / Depart, there are Ground Run Up - Danger Areas diagrams, for idle thrust and T/O thrust. I've been told this diagram does not exist for the B777, and I cannot find it on the Boeing B777 FCTM either. Does such info appear anywhere ?

You better have some serious ballast O/B before bringing a -115-b powered 777 up to power, it will break away fast!

Takeoff starts about the 1:30 mark. Even at low power it accelerates quickly, and rapidly becomes rapid.

Nice.
My experience with the GE90 powered B777 is that you don't need a lot of thrust to get it rolling.
Great airplane :ok:

My AMM says 670FEET (204 meters) for breakaway ;)
There is also a 15' radius inlet hazard area around the nose cone at idle (extending 5' backwards)

" AMM 71-00-00 "
Is AMM the MEL ? ( Minimum Equipment List ? ) If yes, the electronic version on our Company intranet does not have this MEL item listed. There are some MEL items to review, but not this one.
Perhaps it's there in the paper version in the flight deck, but I cannot access that until I go to work next !
On a related topic, do all operators use the same Boeing Minimum Equipment List ?

I see now that the AMM is a different manual from the MEL. It's not available, as far as I know, to the line pilot at my company. Anyone have a link to the B777 AMM ?

Ask your maintenance for a copy.
They should know what that is :O

You can find the charts here:
Boeing: Commercial Airplanes - Commercial Aviation Services - Flight Operations Support - Airport Technology - 777 Airplane Characteristics for Airport Planning (http://www.boeing.com/commercial/airports/777.htm)
Have a look at chapter "6.0 Operating Conditions".
