Not a 747 pilot (not sure why that matters here)... but a pilot. The flight positions are equal. The plane is designed to be flown the same from either flight position and this is routinely done. The guy saying otherwise is talking out their ass.
I said 747 because I was thinking Boeing at the time, and that was the first of their aircraft I could think of!
I was also thinking something smaller like a Cessna might not have the same setup because they're used for very different things (the air travel equivalent of a bus vs. a car).
