Figure 6

Electrodermal activity modulation after the engine failure: (a) mean EDA of maneuvers inside, outside or at the line limit of the height-speed diagram. (b) Mean EDA between different groups of pilot expertise: Group 1 (test Pilots with extensive autorotation experience), Group 2 (test Pilots with lesser autorotation experience) and Group 3 (operational pilots with lesser autorotation experience). (c) Mean EDA results for the four zone regions. The high-hover amplitude was significantly higher than Take-off and Knee amplitudes. (d) Mean EDA response around the engine failure for all maneuvers. We emphasize that these averaged figures are used only to facilitate an overview of the data. For statistics purposes, the effects of repetitions were incorporated in a linear mixed effect model.
