[EN]This study adapted the Demand Resource Evaluation Scores (DRES) as a metacognitive indicator in assessing
pilot students’ perceptions during simulated training of a novel maneuver. Typically, positive DRES are asso ciated with perceiving a demanding situation as a challenge and with improved performance, while negative
DRES are linked to a perception of the situation as a threat, and to poorer performance. The novelty here was to
assess DRES before and after the task and across three missions. Overall, students were found to change their
perceptions from threat to challenge over time. Also, increased DRES were positively correlated with perfor mance progressing from mission to mission, indicating that the students reflect on their performance as they
advance in their training. These findings show that individual metacognitive evaluations of a stressful aviation
maneuver might be important for the progress in performance. The results are discussed in terms of flight safety
and pilot training.
