Aviator Physical Stress
Abstract
The effect of physical stress on the tactical aviator and its impact on mission performance was examined. The physical stresses identified, all consequences of rapid-onset or sustained acceleration during flight, include G-induced Loss of Consciousness (G-LOC), Spatial Disorientation (SD), and neck injury. Though SD as a predominate cause of controlled flight into the terrain has been known for many years, widespread reporting of G-LOC and cervical injury has only occurred during the past decade, coincident with the introduction of high performance, agile aircraft (F-is, 16, 18). The Naval Medical Research and Development Command (NMRDC) requested that the Naval Research Advisory Committee (NRAC) convene a panel to study these problems. Emerging Tactical Aviation (TACAIR) technology will increase the adverse effects of Aviator Physical Stress (APS). The next generation of aircraft will be highly maneuverable and capable of sustaining high-G levels without severe energy tradeoffs. Additionally, the extra weight attributed to helmet-mounted video display systems, night vision aids and laser protective devices will increase the hazard of neck injury in flight. The study begins with a discussion of the historical perspective, changing operational environment, and the impact of emerging technology on APS.
