Who does the final walk around before you take off on a HAA flight. Who disconnects the APU, briefs passengers/patients and helps with radio calls when designated by the FAR part 135 captain. When is the last time a United or Americal Airlines captain assigned those duties to you on a commercial flight. I'm guessing he didn't because you were self loading baggage. Look in your GOM. Far part 1 does not cut it for this argument.
