BACKGROUND Mental workload assessment is a recurrent issue in air traffic control (ATC). Studies of ATC have used either objective aspects, i.e., numbers and distribution of aircraft, or subjective factors, such as self-imposed performance and stress levels, with mixed results. This is partly due to the difficulty in bringing together comparable data(More)
Considerable research has been conducted to identify a useful set of Air Traffic Control complexity factors. It is now necessary to determine, on the one hand, how these factors affect ATC complexity and controller workload and, on the other hand, how ATC complexity and controller workload interact. This line of research should lead to elaboration of(More)
The paper is aimed at studying the perceived strain in professional air-traffic controllers both through self-evaluation and physiological indicators from the autonomic nervous system (ANS). The number of aircraft to be monitored was the main independent variable and could evolve at random within 1 and 10. Five ANS variables were recorded continuously in 25(More)
OBJECTIVE A model of conflict judgments in air traffic control (ATC) is proposed. BACKGROUND Three horizontal distances determine risk judgments about conflict between two aircraft: (a) Dt(o) is the distance between the crossing of the aircraft trajectories and the first aircraft to reach that point; (b) Dt(h) is the distance between the two aircraft when(More)
Two indices are usually used to estimate air-traffic controllers’ workload: subjective self estimation and objective estimation by counting aircraft to be monitored. However, due to uncertainty and real time pressure, the strain undergone by the controller remains difficult to evaluate objectively. The aim of this paper is to test a new index integrating(More)
