The International Civil Aviation Organization (ICAO) has set the fundamental standards for fatigue management in aviation. Its website presents an excellent summary on the approaches to fatigue management, supported by comprehensive resources and guidance material. This includes valuable information from the 2016 Symposium on Fatigue Management Approaches in Aviation.
A range of other resources are available online, including rules in other jurisdictions, industry presentations, and academic research. We've collated some of them for your convenience in the links below.
