Fatigue Risk Management Systems (FRMS) increasingly rely on Biomathematical Models to quantify performance risk and inform operational decisions. These models translate physiology—sleep homeostasis, circadian rhythmicity, and sleep inertia—into actionable metrics such as predicted effectiveness or likelihood of lapses. When implemented correctly, model outputs strengthen rostering, dispatch decisions, and investigation of fatigue-related events while maintaining regulatory […]

Fatigue is a persistent safety hazard in aviation. FSAG is a multidisciplinary team that brings together operators, crew representatives, safety specialists and management to identify, assess and reduce fatigue risk. A well-run FSAG supports a fatigue risk management system (FRMS) and links directly into an operator’s safety management system (SMS). This article explains the FSAG’s […]

We are pleased to announce the completion of the 5-days “Fatigue Risk Management System (FRMS) for Air Traffic Controllers” training program.

A Fatigue Risk Management System (FRMS) is a data-driven, risk-informed, and systematic approach to managing employee fatigue in safety-sensitive industries, particularly in aviation. It is based on scientific principles and knowledge, as well as operational experience, and is designed to ensure that personnel maintain adequate levels of alertness and performance.
