Despite increased use of automation and improvements in display design to improve SA, re-design is unable to completely eliminate accidents of these types. In fact, the increased use of automation continues to add classes of problems related to appropriately coupling and dynamically interleaving human and automatic control.
Automation raises a number of important concerns from the perspective of situation awareness.
Human operators do not always recognize this transition to the degraded mode. Automation can only take into consideration information deemed relevant at the time of its design. As a result operators must learn to effectively discriminate true alerts and alarms from false alarms. This issue is particularly troublesome when automation hands the task back to the operator because it has reached its design limits. One viable option for dealing with many of these problems is training operators to acquire and to maintain situation awareness about the behavior of automation.
