1.14. Tandem Seat Challenges. Limited visibility of the crewmember in the other cockpit makes it difficult to judge intentions, anticipate actions, and verify aircraft systems configuration. Verbal communication must compensate for the lack of intercockpit visibility. Most functions are controllable from either cockpit; however, some items can only be manipulated or directly checked in the front cockpit. To reduce the potential adverse impact of tandem seating:
