When A/T arm FADEC function

[sakukio]

As far as I know after I turn A/T armed , if I advance one of four throttles within 1ch , the rest of three throttles will follow up to the same extent of advanced engine output.
I tried in the PSX but I couldn't notice the difference.
Hope someone could give me some tips

This is called thrust equalization. Page 514 of the Aerowinx manual explains the details.

On the real 744 and in PSX, this feature will not move the throttles; it will directly modulate the related fuel valves.

Don't forget that there is just one throttle motor. Neither the real aircraft nor PSX can move three throttle levers. They always move all four (unless they hit the hard stops). So you need to look at the EICAS thrust gauges to see the thrust equalization in action.
