Effects Of Dextro-Methamphetamine On Subjective Fatigue, C. A. Dejohn, Scott Shappell, D. F. Neri Aug 1992

Effects Of Dextro-Methamphetamine On Subjective Fatigue, C. A. Dejohn, Scott Shappell, D. F. Neri

Publications

Declining aircrew performance during periods of sustained flight operations (SUSOPs) has underscored the need to develop effective countermeasures. This paper reports on the ability of the central nervous system (CNS) stimulant d-methamphetamine to alleviate the detrimental effects of a simulated SUSOPs on subjective fatigue. Subjective fatigue was repeatedly measured by three questionnaires. The simulated SUSOP started at 1800 and consisted of a 9-h planning session followed by 4 h of rest and a 14-h mission. After 6 h of sleep, the 9/4/14 work/rest/work pattern was repeated. At 4 1/2 h into the second mission, 13 subjects were administered 10 mg …

The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri May 1992

The Effect Of Combat On Aircrew Subjective Readiness And Lso Grades During Operation Desert Shield/Storm, Scott A. Shappell, David F. Neri

Publications

The effect of operational tasking on aircrew readiness during combat operations continues to be an area of intense investigation within the U.S. Navy. The recent Persian Gulf War provided a unique opportunity to collect data examining aircrew work/rest cycles and operational tasking in a combat environment. For 4 consecutive weeks during Operations Desert Shield and Desert Storm, 18 A-6 and 18 F-14 aviators onboard the USS AMERICA (CV-66) completed daily work/rest logs of their activities while conducting operations from the Red Sea. Activities on the work/rest logs were coded to a resolution of one-half hour. Several flight parameters were also …

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh Nov 1991

Use Of A Commercially Available Flight Simulator During Aircrew Performance Testing, S. A. Shappell, B. J. Bartosh

Publications

Investigations of aircrew sustained operations (SUSOPS) have been criticized for employing tasks with no apparent external validity. Because measures obtained directly from aviators flying high-performance aircraft are difficult to obtain, a laboratory compromise is needed. High-fidelity flight simulators used for aircrew training offer the most realistic simulation, but their availability is limited. Personal computer-based flight simulators may provide adequate simulation in, the laboratory at a reasonable cost. This report describes a representative research protocol using a commercially available flight simulator during a simulated aircrew SUSOP.
