Recent developments in avionics and ground-sensor technology have led to multiple approachestoward remote traffic control for small, regional airports. We investigated a new operationalconcept considering the simultaneous control of several airports from a single remote location in anexperimental setup. The number of airports and the control principle – that is, the controlof one versus several aircraft at a time – were compared applying a multiple-task paradigm.The impact of both variables on relevant performance indicators was assessed. While performance inissuing clearances was excellent in all conditions, mental effort increased and detectionperformance deteriorated with the number of controlled airports. Surprisingly, the several-at-a-timeprinciple enhanced detection performance for unexpected events and reduced response times tosituational awareness queries.
