Problem with trim

[soldano 0]

On ground before taking off, when I move the yoke trim, the  indicator besides the green string only moves backwards, not forward. Once on flight It cannot be moved anyway, how can I fix this ?.-

Thanks

I had the exact same thing happen. The "problem" is actually a very cool feature and not a problem at all. You have to make sure your controller is exactly centered in order to trim in both directions. For example, if you are pulling back on the yoke, it won't let you use nose-down trim and vice versa. The computer is preventing you from being stupid and trimming in the opposite direction that you are pulling the yoke because obviously, that would very much compound an out of trim situation.

 

In my case, I found that my lovely 3 year old daughter had messed with the "trim wheel" on my CH yoke making the software think I was constantly applying back pressure and therefore it wouldn't let me trim nose down.

Thanks for your reply

In my case your suggestion only works on ground, while flying and using the yoke trim the indicator doesnt move even centering it, although it seems that there is some slight trim working as my CH yoke pressure needed is not so heavy when changing the attitude.-

How that two trim levers in the throttle console work ?
