The fatigue and cognitive performance deficits associated with sleep loss and stress, like that experienced during sustained flight operations and nighttime flying, have motivated the search for effective nonpharmacological countermeasures. The behavioral effects of the potential countermeasure tyrosine, an amino-acid precursor to dopamine and norepinephrine, were examined during an episode of continuous nighttime work involving one night's sleep loss. Volunteers performed nine iterations of a battery of cognitive and subjective tasks for approximately 13 h, beginning at 1930 and ending at 0820 the following morning. Subjects remained awake throughout the day on which the experiment began and were awake for …
Work/Rest Schedules And Performance Of F/A-18 Aviators During Fleet Exercise 1992, Scott A. Shappell, David F. Neri
Work/Rest Schedules And Performance Of F/A-18 Aviators During Fleet Exercise 1992, Scott A. Shappell, David F. Neri
Publications
As a continuation of our previous work during Operation Desert Shield/Storm, we examined the effect a fleet exercise has on the work/rest patterns, fatigue, and cognitive performance of F/A-18 aviators. For 10 days during Fleet Exercise 1992, 25 pilots from VFA-81 and VFA-83 completed daily work/rest logs while performing their usual tasks. Subjective measure of fatigue, quality of rest, and sleep need were also collected. A subset of these F/A-18 pilots completed a brief battery of cognitive tasks as soon before flying as possible and again after the flight debrief. As a group, the pilots were adequately rested with little …
Work/Rest Schedules And Performance Of S-3 Aviators During Fleet Exercise 1992, David F. Neri, Scott A. Shappell
Work/Rest Schedules And Performance Of S-3 Aviators During Fleet Exercise 1992, David F. Neri, Scott A. Shappell

We examined the effect that a fleet exercise has on the work/rest patterns, fatigue, and cognitive performance of S-3 aviators. For 10 days during Fleet Exercise 1992, 21 S-3 aviators from CARRIER AIR WING SEVENTEEN (CVW-17) aboard USS SARATOGA (CV-60) completed detailed daily-activity logs while performing their usual tasks. Subjective measures of fatigue, quality of rest, and sleep need were also collected. A subset of eight aviators completed a brief battery of computer tasks as soon before flying as possible and again after flight debrief. Results indicated that, although the fleet exercise appeared to be below average in difficulty, there …
