What is the best way to shut down a 747 engine?

To understand how the 747-400 flies with only three engines is there a "best" way to shut one of them down while in flight?Cliff

For training practice on three engines. I would suggest shutdown Engine 2 or 3 since they have the least HYD. System Redundancy. Also, do not forget to open all crossfeed valves (if not already open). Set the Transponder to TA only.And you can start a practice for flying 3 engines.If necesary you might need to trim the a/c.

Ofcourse.On the throttle panel, below the throttles there are 4 fuel control switches. They are numbered from, left to right, 1,2,3 and 4.Switch number 3 to cutoff and a few seconds later you will hear a master caution and on the EICAS y'll see >ENG 3 SHUTDOWN

Excellent idea Ramon. I'll watch that video.But I have another question please. Why do I have to trim the aircraft after an engine shut down if the Autopilot is engaged?
