What is aircrew fatigue management and how is it addressed in ARM?

• A. Fatigue is ignored in ARM.
• B. Monitoring rest cycles only during non-mission periods.
• C. Monitoring rest and duty cycles to prevent fatigue; ensures compliant schedules and safety.
• D. Focusing on aircraft maintenance rather than crew schedules.

Answer: (C)

Fatigue management is about preventing crew fatigue by ensuring crews have adequate rest and that duty periods are scheduled in a way that allows recovery. In Aircrew Resource Management (ARM), this is addressed by monitoring both rest and duty cycles to prevent fatigue. The system or program helps ensure schedules comply with regulatory limits on duty hours and required rest, so crews aren’t pushed past safe operating limits and can perform safely. It supports planning and monitoring of flight schedules, adjusting timetables to align with circadian rhythms and recovery needs, and often includes training and procedures to recognize fatigue and apply mitigation strategies.

Choosing to ignore fatigue or to focus only on non-mission periods misses the real purpose of ARM, which is to manage both rest and duty to keep operations safe. Focusing solely on maintenance neglects crew scheduling and fatigue risks, which is why the correct approach is to monitor rest and duty cycles to prevent fatigue and promote safety.
