Subjective Fatigue In A-6, F-14, And F/A-18 Aircrews During Operations Desert Shield And Storm, C. A. Dejohn, S. A. Shappell, D. F. Neri Oct 1992

Subjective Fatigue In A-6, F-14, And F/A-18 Aircrews During Operations Desert Shield And Storm, C. A. Dejohn, S. A. Shappell, D. F. Neri

Fatigue occurring during naval air combat can reduce performance, impair operational effectiveness, and compromise safety. This study examines the effect of combat missions on the subjective fatigue of naval aircrews deployed aboard USS AMERICA during Desert Shield and Desert Storm. Fatigue was determined using three questionnaires that were completed before and after each mission. Although fatigue significantly increased during combat missions, it usually returned to preflight levels by the next day without noticeably increasing as the operation progressed. We feel that judicious aircrew scheduling on the part of operational planners was one of the most important factors contributing to this …


The Effect Of Combat On The Work/Rest Schedules And Fatigue Of A-6 And F-14 Aviators During Operation Desert Shield/Storm, David F. Neri, Scott A. Shappell Aug 1992

The Effect Of Combat On The Work/Rest Schedules And Fatigue Of A-6 And F-14 Aviators During Operation Desert Shield/Storm, David F. Neri, Scott A. Shappell

Publications

During Operation Desert Shield/Storm, A-6 and F-14 aviators aboard USS AMERICA completed daily activity logs and provided subjective measures of fatigue. Aviators flew frequently at night during Desert Storm, but without substantial sleep-related fatigue or problems. A likely contributing factor was the large number of naval aviation assets brought into the combat theater, allowing workload to be shared and activity and rest times to be properly managed. However, raster plots of the data suggest that there may have been an additional contributing factor. The AMERICA travelled eastward from the east coast through seven time zones and became involved in combat …


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

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 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 …


Factor Analysis Of The Personal Profile System, Thomas G. Henkel, James Noel Wilmoth Jan 1992

Factor Analysis Of The Personal Profile System, Thomas G. Henkel, James Noel Wilmoth

Publications

Principal components extraction with orthogonal and oblique rotations tested construct validity for the Personal Profile System. MOST-LIKE endorsements of 96 behavioral descriptors were coded with 4, LEAST-LIKE with 1, and unendorsed with 2.5. Descriptor data from 1,045 senior noncommissioned Air Force officers were normalized. Four factors accounted for 85% of total variance, with 19 descriptors loading significantly on two factors and the remaining 77 on just one factor. The measure of sampling adequacy for every descriptor exceeded .94. One factor for the varimax-rotated (best) analysis was bi-scalar, loading on Steadiness and Compliance descriptors; a second resembled Influencing, a third loaded …
