What's wrong with fokker 100 throttles?

Hi guys . check this out :

look at the throttle lever . the right one is noticeably more forward than the other one . and it's not the first f100 I seen to be like this. even EPR indicators show a differential thrust there too. I've been flying many years with digital aviation fokker 100 in fs9 and fsx and I noticed this too but didn't know the reason behind it.

They do that. It's very common and annoying and it can be fixed. There are a variety reasons for throttle stagger and some include poorly set up engines, engines with differing ages (and TG margins), autothrottle rigging problems, bleed variations (including rigging) and so on. There is a limit to the amount of stagger allowed but I can't tell you what it is.

I seem to remember that one throttle knobs width was the maximum acceptable stagger at equal EPR. Often, the split is different depending on thrust setting: an aircraft might show next to no stagger at TOGA power but rather noticeable split at or close to idle setting.
