If an aircraft is yawing left, the trim tab on the rudder would be positioned
- to the right, deflecting the rudder left.
- back to its neutral centre position.
- to the left, moving the rudder right.
Explanation from PART66Online
To stop a persistent left yaw the rudder must hold a steady right deflection. The trim tab moves opposite to the surface it trims, so the tab deflects left; the airflow on the tab then pushes the rudder trailing edge to the right and holds it there without continuous pedal force.

You are wrong. :) Read question carefully or read Module 8.

If the a/c is yawing left, i assume its nose is yawing to left that means tail to the right, for that rudder should bend left and trim tab to the right.
Please correct me,
Thank You,

If aircraft is yawing to the left, you have to move rudder to the right, otherwise you will get more yaw. Here is basic example about flight controls: youtube.com/watch?v=5KWOzgGbFrw
To move rudder to the right you have to move trim tab to the left. I hope you now understand.

I got you now,but this question should be amended, it doesn't explains properly. I guess this question is about how the trim corrects the directional stability ?

Trimming and stability are different topics of aerodynamics. This question is about trim tab and I think it is clear enough if you are familiar with aerodynamics. On your official exams you will meet a lot of questions which will try to confuse you. :)

If aircraft is yawing to the left, you have to move rudder to the right, is not correct...

Question is about TRIM TAB on rudder, not about rudder itself. Please read question carefully.

ok but the answes say the trim tab to the left, moving the rudder right... moving the rudder right the nose of the plane will move right.

Right. To correct left yaw you have to turn nose right.
Do you understand what is left yaw?

ok maybe this question can be interpreted in 2 manner...

But this Q aircraft is yawing left so rudder is move left and trim tab is move right. Because trim tab is move opposite side of rudder.
right or not pls explain. . ...

khatar, I have already explained above. This question is 100% clear for understanding. Just read question and module 8.

dimky was not clear enough!! YES..it's about correcting the yawing to the left, that means that you will have to yaw on the right...trim tab left...
Same question on Module 11 but different formulation:
If an aircraft is yawing to the left, where would you position the trim tab on the rudder?

Guys listen... i was thinking and puzzled about this question as you do, now i got it...
Remember the function of trim tab, its not to yaw. It is used to reduce pilot work load. Question says aircraft yaw to left, so pilot have to constantly give input to right instead of that we can use trim tab that can move rudder to right without pilot constant input, for right rudder movement it has to move left... so Remember guys its the function question is asking
