Abstract
European Air Traffic Management Program (CARE, 2003) recommendations for a 3- phased approach to workload assessment provided Transportation Safety Board investigators insight into how operating conditions for approaches into a non-radar airport under instrument meteorological conditions impact crew workload. It was possible to develop and use secondary task questions for three of four cognitive task domains. Qualitative assessment of verbal responses illustrated how crews use verbal information to support mental models. A trend towards longer response times for the cognitively more demanding questions supported the hypothesis that maintaining situational awareness of flight status within the approach sequence is cognitively more demanding than monitoring flight control indicators. Changes in heart rate variability could be linked to changes in task demands. NASA Task Load Index data provided quantitative and qualitative indicators of overall workload and demonstrated that high workload conditions can be triggered by a variety of operational conditions.
