The increased role of automation in systems has enhanced many aspects of system operations, but it has also led to unique antecedents to errors, errors that have led to incidents and accidents. Operators committing automation-related errors often fail to effectively monitor the systems, or to understand the effects of their actions or those of the automation. Some operators have demonstrated greater trust in the abilities of the automation to control the system than in their own abilities. The system was designed to automatically default to dead reckoning navigation, a method that did not compensate for wind, current, and sea state, when global positioning satellite signals became unavailable. Modem systems also offer flexibility to the design of both displays and controls. This enhances safety by displaying highly interpretable and accurate system-related information, benefiting situation awareness and increasing operators' abilities to recognize and respond effectively to system anomalies.
