Mission Crew Fatigue during RIVET JOINT Block II Demonstration/Evaluation

RIVET JOINT is a USAF Electronic Systems Command (ESC) airborne (RC-135) reconnaissance system. The objectives of an ongoing modernization program are to improve mission capability and manpower utilizaiton through use of state-of-the-art computer technology and surveillance equipment. A prototype modernized system recently underwent testing and evaluation in the real-world operational environment. ESC/SD requested that the USAF School of Aerospace Medicine (USAFSAM/VN) evaluate the impact of the system on operator stress and fatique. Psychobiological data were systematically collected from 13 operators over 6 consecutive days, including two 8-hour airborne test missions. The subjective fatigue and physiological cost associated with the test missions were moderate and did not suggest compromises in performance and safety. The operators were fully recovered from each of the test missions after an extended postmission night of sleep. (Author)
