Situation awareness error detection

Error detection mechanisms were found to share much in common with the strategies identified above for error avoidance, as effective error detection depends to a large degree on maintaining situation awareness. However, aside from a focus on situation awareness, the interview data suggest that effective error detection also includes a range of multi-crew coordination factors, as well as unique attitudinal factors. A total of nine components of error detection were identified, under three broad categories. 

Firstly, the model makes explicit that the cracial mechanism involved in error detection is that of mismatch emergence, whereby conflict arises between the expected state of the work system and the actual observed state of the system. The results of this study emphasize the role of situation awareness, and in particular the constmction of a dynamic mental model of the desired and expected state of the system the aircraft status and configuration in space and time. This study has identified a range of cognitive and metacognitive processes that provide an adequately comprehensive framework for mismatch emergence to reliably occur. 

The Airbus flight control system provides information to the eiew in order to ensure situational awareness at an appropriate level. In addition to this information and to manage situations of detected failure at their level or to prevent pilot errors, aircraft systems can trigger alarms in the form of audioAdsual warnings, or implement a semi-automatic command (see section 6.1.4).
