Eight Air traffic controllers carried out exercises using a TRACON II ATC Simulator. After a training and familiarisation day, the controller carried out four simulation exercises, two low and two high traffic load. His performance during each exercise was recorded, A self-assessment questionnaire for fatigue and a test of cortical evoked potential were applied and a sample of saliva was taken for cortisol analysis before and after each experimental session. The NASA-TLX was completed after each exercise and a test of alpha-rhythm attenuation was carried out at the start and end of each day.
