A question what are these two levers for ...? Take trim capture .. What function do they have? And I'm surprised that it actually works if you move the levers, the trim and ruder moves is incredible ... Congratulations ipacs team .. For these details, aerofly is my favorite mobile simulator for the realism it has
These are the rudder trims. If one engine fails (which you can do in the a320 for example) the aircraft yaws towards the side of the failed engine because the remaining engine is still pushing forward and the other one creates drag.
To compensate you have to apply opposite rudder and you have to keep hoping a lot of it.
The pilot applies rudder trim to relief the rudder pedal forces. In the a320 and b777 the fly by wire also automatically compensates thrust asymmetries but currently this is not implemented.
