Engineers speak of a “control loop,” in which the “man in the loop” is the problematical element. This is the human component in a series of sequentially interacting pieces of equipment that control or adjust a function. But when the pilot is suddenly and unexpectedly brought into the control loop (in other words, participates in decision making) as a result of (inevitable) equipment failure, he is disoriented. Long periods of passive monitoring make one unprepared to act in emergencies. The sudden appearance of several alarms, all there for safety reasons, leads to disorientation.
