Few studies include electrodermal and pupil diameter measurements probably due to strong operational constraints. These measures are well-known for being sensitive to mental workload. In a flight framework, the addition of electrodermal activity sensors does not complicate the experimental protocol (wristband wearing) whereas pupillary diameter recording requires a much more sizeable device (eye tracker utilization). In the experiment presented in this paper, heart rate, respiratory rate, skin conductance and pupil diameter were collected during simulated tactical flights. The main novelty of the proposed experimental design relates to eye tracking device integration into a highly realistic flight simulation. To cover the entire pilot visual field and prevent measurement loss, a double-tracking design was tested (i.e. combination of two optical pairs). Preliminary analysis overall confirmed the reliability of this experimental setup showing a high quality of measurement. Nevertheless, extra care should be taken for the skin conductance signal that seems particularly sensitive to movement artefacts. Owing to the observed reliability of data acquisition from the eye tracker it may be possible to extend the proposed device to ocular behaviour measures (scanpaths) in highly realistic flight simulation. Introduction The current evolution of aeronautical systems towards unmanned solutions (UAVS, UCAV) brings the place of the human operator in these systems to the foreground. The TAPAS project (stands for Technique d’Analyse pour le Partage d’Autorité dans les Systèmes des systèmes /Analysis Techniques for Shared Authority in the Systems of systems) is a French project between Dassault Aviation, Telecom Bretagne and University of South Brittany. It aims at developing a method for analysing and evaluating different configurations of Human-Human collaboration to enhance the reliability of Human-System relationship. One of the main challenges of this approach is to understand the potential limitations of using these highly autonomous future systems and to define new design principles. The originality and ambition of TAPAS mainly lies in the development of an innovative method, strongly focused on human factors (workload) and related to a design process of new drone control systems.
