INTRODUCTION Bio-mathematical models are increasingly used for predicting fatigue in airline operations, and have been proposed as a possible component of fatigue risk management systems (FRMS). There is a need to continue to evaluate fatigue models against data collected from crews conducting commercial flight operations. METHODS A comparison was made between several in-flight studies of pilot fatigue, conducted over a 10-yr period on a variety of operations, and the predictions of a widely…

Multimodal Analysis of Eye Movements and Fatigue in a Simulated Glass Cockpit Environment
TLDR
The results show the promise of using non-intrusive eye movements as an indicator for fatigue prediction and provides a foundation that can lead us closer to developing a near real-time warning system to prevent critical accidents.
Metody hodnocení únavy u pilotů Methods for evaluation of fatigue in pilots
TLDR
It is necessary to im prove the way fatigue is detected in p ilots nowadays w ith an introduction of newer m ore accurate m ethods of drowsiness evaluation and by acknow ledging the lim itations of the currently used m ethod.

Risk of Performance Decrements and Adverse Health Outcomes Resulting from Sleep Loss, Circadian Desynchronization, and Work Overload
TLDR
Efforts are needed to identify the environmental and mission conditions that interfere with sleep and circadian alignment, as well as individual differences in vulnerability and resiliency to sleep loss and circadian desynchronization.

Comparison of mathematical model predictions to experimental data of fatigue and performance
As part of the"Fatigue and Performance Modeling Workshop,"six modeling teams made predictions for temporal profiles of fatigue and performance in five different scenarios. One scenario was based on a
Comparison of mathematical model predictions to experimental data of fatigue and performance.
TLDR
Differences among the predictions from the six models were relatively small, suggesting that these models have a broad common basis, and more experimental research is needed for the further development of fatigue and performance models.
Automated collection of fatigue ratings at the top of descent: a practical commercial airline tool.
TLDR
The results suggest that the automated collection of subjective ratings is a valid way to collect data on fatigue in an airline setting and has potential benefits for the crew in assessing fatigue risk prior to approach, as part of a fatigue risk management system.
Fatigue in airline pilots after an additional day's layover period.
TLDR
The results suggest that the addition of an extra night's layover has different effects depending on the type of operation, but the benefit of increased layover time may be limited if time-zone shifts cause a mismatch between local time and the circadian rhythm of sleep.
Summary of the key features of seven biomathematical models of human fatigue and performance.
TLDR
Although all models appear to have been fundamentally influenced by the two-process model of sleep regulation by Borbély, there is considerable diversity among them in the number and type of input and output variables, and their stated goals and capabilities.
Modeling performance and alertness: the QinetiQ approach.
TLDR
It is concluded that further work is needed in three areas: cumulative fatigue, the impact of sleep architecture, and the prediction of performance for complex tasks in systems.
Fatigue in trans-Atlantic airline operations: diaries and actigraphy for two- vs. three-pilot crews.
TLDR
The study indicates that the reduction of crew size by one pilot is associated with moderately increased levels of sleepiness, and it is suggested that time allotted to sleep in the two-pilot condition might be somewhat extended to improve alertness.
Irregularity of rest and activity: studies on circadian rhythmicity in man.
TLDR
Rectal temperature, electrolyte excretion and performance were studied in young adults who followed an irregular pattern of work and rest for 9 days in an isolation unit and there was evidence of deterioration in performance during work periods which exceeded 9 h, but there was no evidence of progressive deterioration over the 9 day schedule.
