What should aircrew do if their crew rest is interrupted?

If aircrew experience an interruption of their crew rest, the appropriate action is to immediately inform the Pilot in Command (PIC) and start a new crew rest period. This step is crucial because adequate rest is essential for maintaining operational safety, situational awareness, and decision-making capabilities during flight operations. Interrupting crew rest can lead to fatigue, which negatively impacts performance and increases the risk of errors.

In situations where the crew's rest is compromised, it's vital to communicate this to the PIC to reassess the flight's operational status. Starting a new crew rest period allows aircrew to recuperate properly before resuming duties, ensuring they are fit for safe operations. Prioritizing rest not only helps safeguard the well-being of the crew but also mitigates risks to the aircraft, passengers, and mission objectives.
