Can a SIC legally sit left seat?
I got into an argument yesterday with a POI at a FSDO about whether or not a non-type rated pilot can sit in the left seat during the legs they fly. I have not seen any where in the regulations where a SIC can or cannot sit in the left seat. As a captain, it was very helpful for me to become familiar with the airplane by flying it from the left seat when the guy I was flying with felt comfortable with it.
Do the regulations address this anywhere?
