| Abstract: | Since 2010, the Netherlands has had the NH-90, which is the substitute for the Lynx helicopter of defence. The flight time increased from a maximum of three hours in the Super Lynx 300 to a maximum of five hours in the NH-90. It is important that the two pilots are alert enough to operate the helicopter. This study investigated how the increased flight time influences the fatigue level of the pilots and how severe fatigue can be avoided through Flight Time Limitations (FTL). Using the bio-mathematical models SAFTE-FAST and FRI, the effect on fatigue of a flight schedule with 39 flight hours and one with 25 flight hours per week was tested according to the steps of the Fatigue Risk Management System (FRMS). Both schedules were twelve weeks long. Hazards were identified and their risks were assessed. Three mitigation strategies were formulated, which were evaluated during a second study with the BAM and the SAFTE-FAST. The resulting advice is to restrict flight time to 4.5 hours. During the afternoon shift, a flight after 10 pm must not be longer than three hours. Besides, a flight during a night shift must not be after 6 am. |
