For all missions, the pilot flying the aircraft was assigned to the front seat, and the pilot operating the MEP was
assigned to the back seat. Pilots alternated between the front seat and back seat positions during each phase. A total of 30 missions was conducted during the
FDE.

The pilots completed 39 missions during FDTE I. For all missions, the pilot who flew the aircraft was assigned to the front seat and the pilot who operated the mission equipment package (MEP) was assigned to the back seat
Comanche is still in testing at that time ,but i think its enough proof that the first seat is design for pilot who fly the aircraft.
