Analysis mode in CrewAlert Pro allows a user to quickly position to a 'virtual time' - and then perform detailed analysis of a situation using the Boeing Alertness Model BAM at that moment. This can be used for analysis of predicted body clock time, sleep debt and investigating fatigue causes and safety performance indicators for a fatigue report, incident or accident.
In this short video here you can see how the functionality is used for the Mangalore accident.
Please find more information here on safety performance indicators and the fatigue causes functionality in CrewAlert Pro. Enjoy.
