A320 Rudder Trim PB / Nose Gear ?
Gents
My understanding is the rudder trim is a "FAC thing" and has no physical relationship/linkage to the nose landing gear. However during an after-start flow the other day, a Captain told me to "hold on, rudder trim until tow bar is disconnected, as we don't want the nose wheel to move at all." I said yes sir but it got me to thinking about this. (after start flow being requested while tow bar still attached is another conversation...)
I have looked back into our training materials and FCOM stuff and cannot located any information that the rudder trim PB can cause the nose gear to move. I respect everyone's experience so maybe it is buried somewhere. Possibly on other aircraft it is and this was "leftover" from the Captain's thousands of hours in other airplanes.
Thank you
