What must a crewmember do if they need to be removed from duty due to fatigue?

When a crewmember needs to be removed from duty due to fatigue, notifying the Operations Control Center (OCC) as soon as possible is essential. This action allows the OCC to manage the scheduling of flights and crew members appropriately, ensuring that safety remains a top priority. The OCC can arrange for a replacement or make necessary adjustments to the flight schedule to accommodate the change, thus minimizing potential disruptions and ensuring compliance with regulations that mandate the health and well-being of flight crew.

While informing the Flight Operations Duty Manager (FODM) and advising other crew members may also be important steps in the process, the primary action for the crewmember is to communicate with the OCC. This ensures that all necessary adjustments are made swiftly and efficiently, promoting a culture of safety and responsibility within the operation. Submitting a formal report might be required later but is not the immediate action required when addressing the issue of fatigue.
