On large commercial airliners with required two-person crews, how are
duties usually divided between the captain and the first officer? Are
there specific rules, or are there simply standard conventions, or
does it vary by airline/pilot, or what? Who flies the airplane at
which time, and what does the non-flying pilot do during those times?
