AbstractThe Advanced Integrated Multi Sensor Surveillance (AIMS) electro-optical system and Night Vision Goggles (NVG) are both used to conduct a simulated airborne Search and Rescue (SAR) search task aboard NRC’s DHC-6 Twin Otter. The following is a case study comparing the psychological and physiological impacts associated with either form of search and rescue. Two operators performed detection/discrimination search tasks, alternating between AIMS and NVGs, over 11 flights. Subjective data, such as the Dundee Stress State Questionnaire (DSSQ) and Psychomotor Vigilance Task (PVT) were collected both pre- and post-flight. Physiological data, including continuous Electrocardiography (ECG) and respiration, was collected throughout each flight. Heart Rate Variability (HRV) was derived from the ECG. Differences in metrics across tasks suggest that physiological arousal was significantly higher when performing the task with the AIMS system compared to performing the task with the NVGs for the two operators evaluated.
