A comparison of one- and two-person crew performance in a supervisory control task

One- and two-person crews performed a simulated supervisory control task in which they had to directly control a scout helicopter and indirectly control four friendly helicopters in a hostile environment. One-person crews relied on an autopilot more than two-person crews in order to deal with multiple task demands. However, two-person crews were superior in terms of overall performance, and on particular subtasks such as searching for cargo and enemy craft and destroying enemy craft after they were located.
