Fatigue Countermeasure Program in Operational Flight Controllers
Completed · Not applicable
Conditions studied: Fatigue
In brief
The purpose of this study is to validate the acceptability, operational feasibility and efficacy of a combined fatigue countermeasure comprised of shorter-wavelength light and exercise during operational Orbit 1 night shifts to improve alertness and performance of flight mission controllers. Specifically, the investigators will: 1. Feasibility. Test the feasibility of developing a break room containing fatigue countermeasures (shorter-wavelength light and exercise equipment) to be used by flight mission controllers during Orbit 1 night shifts, and the feasibility to schedule regular breaks during the Orbit 1 shift so that flight mission controllers have the opportunity to use the fatigue countermeasures break room. 2. Acceptability. Test the acceptability of the use of the fatigue countermeasures break room evaluating when and how the room is used by flight mission controllers, as measured on End-of-Shift Productivity Questionnaire. 3. Test the hypothesis that alertness and performance will be impaired in flight mission controllers during Orbit 1 operational night shifts as compared to flight mission controllers working a non-console day shift. 4. Test the hypothesis that alertness and performance of flight mission controllers who exercise and are exposed to shorter wavelength light during the Orbit 1 night shift will be significantly more alert and have better mood, performance (e.g., less Psychomotor Vigilance Task (PVT) lapses, increased productivity) than those same mission controllers working Orbit 1 night shifts without exposure to the shorter wavelength light and exercise. 5. Test the acceptability, operational feasibility and efficacy of implementing an anonymous sleep disorders screening for flight controllers, evaluated by number of visitors to the screening web site and the number of completed assessments.
