“…These new systems are then validated under different workloads that have focused primarily on deviations in traffic load (e.g., Verma et al, 2007;Martin et al, 2011). A few projects have included operational complexities such as a configuration change (e.g., Stelzer et al, 2011). The traffic load is also modulated in some cases regarding the type -a mixture of arrivals and departures, or entirely homogeneous.…”

This is an author-deposited version published in: http://oatao.univ-toulouse.fr/ Eprints ID: 16193 Evaluating future technology concepts for air traffic control ground operations requires exploration of work scenarios of differing complexities, i.e. scenarios that create more or less taskload for air traffic controllers. While the link between traffic load and workload has been well-characterized in the literature and is often the only complexity variable applied to validation studies, there are other operational events that can augment controller workload. Through a series of interviews and on-site observations of professional and student air traffic controllers, we defined seven general operational events that can be applied to all airport ground operations. We discuss the development of two scenarios of different workloads (average and hard) and their validation with air traffic controllers. INTRODUCTIONIn addition to augmenting the number of aircraft in the air space, the forecasted growth of air traffic also increases the number of ground movements at busy airports (Eurocontrol, 2013), adding increased collision risk, time delays, pollution, and stress for the air traffic control (ATC) officer (ATCO). As feasible solutions are explored, most of which involve the inclusion of ground automation and in-cockpit or in-tower technology, it is important to ensure that such solutions are robust to the ATCO's workload. Therefore, work scenarios of different workloads (i.e., taskloads) and complexities must be designed and evaluated. In particular, it is important to characterize the different sources of complexities for the tower ATCO. Much has been written in the literature regarding link between workload and traffic load, visibility, and tool utility, but less has been discussed regarding operational events. Such events can be used individually or in combination depending on project aims and the general experience of the participant body. Furthermore, the majority of the work done in this field has focused on air traffic management en route and not on the ground. This paper describes the general operational events that can contribute to scenario complexity specifically for the ground (GND) ATCO. We begin with a review of current literature regarding scenario complexity in tower ATC operations. Next, the general methodology is described, including the demographics of the persons interviewed and observed. The first half of this paper concludes with a definition of the seven operational events that can be used to increase taskload complexity of the GND controller. The second half of the paper introduces two scenarios, Average and Hard, that were developed for the evaluation of modern taxiing techniques and ends with the scenario validation and concluding thoughts.
