SART measurement dimensions.

Dimension	Construct	Measurement item
Attentional demands	Instability of situation	Stability of traffic environment and vessel in the pilotage (without emergency)
	Variability of situation	Number of variables, including navigational and environmental elements, that should be the focus in pilotage
	Complexity of situation	Complexity of the traffic in pilotage waters
Attentional supply	Arousal	Alertness of pilots in pilotage
	Spare mental capacity	How much residual energy should be used to handle emergencies in pilotage
	Concentration	Degree of concentration at initial pilotage
	Division of attention	Ability to notice multiple information variables simultaneously in pilotage
Understanding of the situation	Information quantity	Amount of information received and understood
	Information quality	Reliability of perceived information
	Familiarity	Familiarity of pilotage waters
