Premiair TOD Survey

Top of Descent survey for Fly Premiair.

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.

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
