CAS-5 Fatigue Risk Model

The CIRCADIAN® Alertness Simulator (CAS) is the longest operationally used fatigue model with a 20-year validated record of reducing errors, incidents, and injuries in FRMS applications.

Download the CAS 5 Crew Planners BrochureDownload the CAS 5 Crew Planners BrochureThe latest version of CAS (CAS-5) is specially optimized for airline FRMS to assess fatigue risk in crew pairings, bidlines, and day of operations data. Some of the key features of CAS-5 are:

  • Designed for short haul/commuter, long haul, freight and corporate operations
  • Can track pilots, flight attendants, and ground crew
  • Supports crew planning, crew pairings, bidlines, and crew requirements
  • Scientifically optimized with sleep/fatigue data
  • Full featured: crew type, duty type, rest type, time zone shifts, etc.
  • Personalized to individual sleep
 

FACTS™ - Aviation Fatigue Incident Analysis

You don’t need a panel of experts to determine how many incidents reports are caused by fatigue–related errors, or the annual cost of fatigue events.

FACTS™ (Fatigue Accident/Incident Causation Testing System) solves this problem using a scientifically validated expert web-based system which objectively analyzes fatigue probability. FACTS™ probability judgments correlate 86% with the decisions of an expert human panel.

FACTS™ can be linked to ASAP and fatigue reports to provide an objective assessment of fatigue with specific versions available for flight and ground crews. CIRCADIAN® also licenses a secure corporate version of FACTS™ which enables to you to store and analyze all fatigue reports and causal factors.

CIRCADIAN® Aviation Research: Data Collection & Analysis

CIRCADIAN® has the global scientific resources and 20-years of expertise in conducting large scale studies of aircrew fatigue in passenger and freight operations. We have helped define the standard for collecting sleep, fatigue and aircrew performance data in airline studies. By collecting sleep and alertness data in its own operations, an airline can refine and optimize the alertness predictions to incorporate the unique characteristics of its operators in the CAS-5 fatigue risk model.
