AMC1 ORO.FTL.120(b)(4) Fatigue risk management (FRM)
CAT OPERATORS IDENTIFICATION OF HAZARDS
The operator should develop and maintain three documented processes for fatigue hazard identification:
(a) Predictive
The predictive process should identify fatigue hazards by examining crew scheduling and taking into account factors known to affect sleep and fatigue and their effects on performance. Methods of examination may include, but are not limited to:
(1) operator or industry operational experience and data collected on similar types of operations;
(2) evidence-based scheduling practices; and
(3) bio-mathematical models.
(b) Proactive
The proactive process should identify fatigue hazards within current flight operations. Methods of examination may include, but are not limited to:
(1) self-reporting of fatigue risks;
(2) crew fatigue surveys;
(3) relevant flight and cabin crew performance data;
(4) available safety databases and scientific studies; and
(5) analysis of planned versus actual time worked.
(c) Reactive
The reactive process should identify the contribution of fatigue hazards to reports and events associated with potential negative safety consequences in order to determine how the impact of fatigue could have been minimised. At a minimum, the process may be triggered by any of the following:
(1) fatigue reports;
(2) confidential reports;
(3) audit reports;
(4) incidents; or
(5) flight data monitoring (FDM) events.
EASA aviation regulations require operators to implement fatigue risk management. This includes documented processes for identifying fatigue hazards through predictive scheduling analysis, proactive monitoring of current operations, and reactive investigation of safety-related events. These processes aim to minimize the impact of fatigue on flight safety.
