Top of Descent survey for Corendon Airlines.
In this study, flight crew rate their fatigue at TOD (or predicatively / retrospectively if TOD is not a suitable time for data collection). Rating fatigue from prior duties enables the identification of sectors that are not fatiguing in themselves, but may be fatiguing due to previous sectors worked.
Visual Analogue Scale (VAS).
A Visual Analogue Scale (VAS) is a horizontal line across the bottom of the page measuring between 0% and 100%, with a word at each end representing two extremes of day time sleepiness. This app has set the scale as “very sleepy” being 0% and “very alert” being 100%. The subject is asked to place a mark at that point on the line that represents his/her current state along that continuum. The VAS score is the distance (measured in mm) between the subject’s mark and one or other end of the line, converted to a percentage alertness level.
Results
Statistics that can be calculated as a result of TOD studies include:
- Fatigue at TOD by sector – rate all sectors
- Flight duty periods with a high fatigue rating at the start of duty
Sectors with abnormal accumulation of fatigue; e.g.large difference between start of duty fatigue ratings and fatigue ratings at TOD or end of duty
