The standard Boeing 747-400 that comes with original FS2004 is not accurate; its engines develop too much thrust while being too weak at idle, and the cruise settings are incorrect. By Pedro Oliveira.
This file has saved me a lot of headaches as it solved a problem I was having with FS9's default 744 doing two moves that should be impossible in the real world, let alone FS, whenever I got remotely close to the maximum thrust of 63,300 pounds (28,122 Kilograms) for the default PW4062 engine.
The only drawback as far as I can tell, is that you have to start lowering your rate of climb at about 28,000-32,000' (8,534-9,753 meters) depending on your total gross weight and indicated speed, or you run the risk of stalling.
