What is not known is how much of a common image is needed to enhance performance and what knowledge or processes need to be held in common. Drawn by Dr. Accordingly, rather than rely on a single approach or metric, valid and reliable measurement of SA should utilize a battery of distinct yet related measures that complement each other e. Perceptual knowledge sources encode sensory data and post it on to appropriate locations of the blackboard level 1 situation awareness , while other knowledge sources reason about the information posted level 2 situation awareness and make inferences about future situations or states level 3 situation awareness , posting all their conclusions back onto the blackboard structure. Repeat this attention pattern over and over again. In these efforts, the situation awareness model was developed as a production rule system in which a situation is assessed using the rule "if a set of events E occurs, then the situation is S. The following are common events identified in accidents that have involved a loss of situation awareness.

More sophisticated use of production rules e. The main advantage of performance measures is that these can be collected objectively and without disrupting task performance.
The pilot is unaware of the existence of an airspace reservation and enters it without clearance resulting in Loss of Separation from another aircraft e. Stress and Workload - Stress affects our ability to process information.
