Abstract:

INTRODUCTION: Fatigue is an important phenomenon in modern aviation. Despite the progress in research concerning fatigue among civil aviation and military pilots, fatigue in student pilots has remained unexamined. The aim of this study was to examine fatigue among ab-initio pilots. In this study, the fatigue model previously proposed and used in the literature is redesigned for ab-initio pilots.METHOD: A 48-item questionnaire was applied. Factor analysis was performed using SPSS. The data were collected from 114 ab-initio pilots.RESULTS: It was determined that 23% (N 26) of the participants in

Abstract:

Performance decrement associated with pilot fatigue is considered a leading contributor to aviation accidents and fatalities. The output of prevalent pilot fatigue methodologies (both subjective & objective) either suffer from human judgement bias or require complex data processing. Moreover, studies catering to long duration flight missions have not been performed. Presently, we investigate the impact of fatigue on pilot performance for long duration of a flight mission composed of multiple take-offs and landings. We propose a new multimodal approach that integrates traditional fatigue me

Abstract:

This study attempts to examine the fatigue of pilots who fly the commercial aircraft on short route since they have to make several take-off and landing during their duty time for short route flight. The method of paired t-test was used to measure the condition of the pilots before and after their duty time. In addition, the factors that the pilots most felt in contributing to the level of fatigue were also explored in this study. The results indicate that the pilots experience fatigue when flying short routes in their duty time and the factor that contributes the most to the pilots’ fatigue i

Abstract:

Fatigue is an important factor affecting modern flight safety. It can easily lead to a decline in pilots’ operational ability, misjudgments, and flight illusions. Moreover, it can even trigger serious flight accidents. In this paper, a wearable wireless physiological device was used to obtain pilots’ electrocardiogram (ECG) data in a simulated flight experiment, and 1440 effective samples were determined. The Friedman test was adopted to select the characteristic indexes that reflect the fatigue state of the pilot from the time domain, frequency domain, and non-linear characteristics of the ef

Abstract:

In order to assess airline pilot duty fatigue levels associated with normal operations, subjective fatigue, sleep cycles were unobtrusively monitored and compared to the estimates of a fatigue prediction algorithm (FADE). A group of 9 commercial airline pilots completed log sheets on which sleep, flight data and periodic estimates of fatigue levels were recorded over a 10-day period. The subjective fatigue scores indicated a significant increase during the 2000-0400 hours time block. The lowest reported fatigue scores occurred during the 0800-1200 hours. Hours of sleep predicted pilot fatigue

This study involved over-the-road testing of four fatigue management technologies (FMTs) in trucking operations in Canada and the United States. Technologies bundled into a single intervention came from four fatigue management domains: one providing objective information on driver sleep need, one providing objective information on driver drowsiness, one providing objective information on lane tracking performance, and one reducing the work involved in controlling vehicle stability while driving.

Abstract:

Abstract Objective The FEAr pilot study was conducted to evaluate the construct validity of an instrument that measures self-reported fatigue levels among air medics (the Flight Risk Assessment [FRA] measure). Data Selection The population of interest, flight medics, is highly specialized and relatively small. As a result, non-probability, convenience sampling was used (N = 27). The participants were recruited from one air medical company with bases located across ten western states. Medics took two measures, the FRA and the PVT, three times a day, for three days.

Abstract:

BACKGROUND: In-flight breaks are used during augmented long-haul flight operations, allowing pilots a sleep opportunity. The U.S. Federal Aviation Administration duty and rest regulations restrict the pilot flying the landing to using the third rest break. It is unclear how effective these restrictions are on pilots ability to obtain sleep. We hypothesized there would be no difference in self-reported sleep, alertness, and fatigue between pilots taking the second vs. third rest breaks.METHODS: Pilots flying augmented operations in two U.S.-based commercial airlines were eligible for the study.

Abstract:

The purposes of this pilot study are to describe the 24-hr patterns of dyspnea, fatigue, and peak expiratory flow rate (PEFR) in patients with chronic obstructive pulmonary disease (COPD) and examine their interrelationships. The repeated-measures design protocol involved 10 patients with moderate to severe COPD who self-assessed dyspnea, fatigue, and PEFR five times a day for 8 days. Circadian rhythms were documented by single cosinor analysis in 40% of the participants for dyspnea, 60% for fatigue, and 60% for PEFR. The 8-day, 24-hr means of dyspnea and fatigue were moderately correlated; 70

Abstract:

Abstract Objective Chronic low back pain (CLBP) is associated with fatigue, pain, poor sleep, and disability. Acupressure is a low-risk treatment option used to manage symptoms in other groups, but its efficacy, particularly on fatigue and sleep, is unknown in CLBP. This study examined preliminary effects of two types of self-administered acupressure (relaxing and stimulating) on fatigue, pain, sleep, and reported disability. Methods A randomized pilot trial was conducted (N = 67) in which participants were randomized into six weeks of relaxing acupressure, stimulating acupressure, or usual ca

Abstract BACKGROUND Fatigue is common and disabling for brain tumour patients. We studied the feasibility of two innovative lifestyle coaching interventions for high fatigue. METHODS Multi-centre phase II feasibility RCT (ISRCTN17883425). Adult primary brain tumour outpatients reporting significant fatigue (Brief Fatigue Inventory [BFI] score 4+), were randomised to one of three arms: Control; Health Coaching (“HC”, comprising eight structured coaching sessions on lifestyle behaviours); or HC plus Activation Coaching (“HC+AC”, adding two structured interviews targeting motivation to change).

Abstract:

Cancer-related fatigue (CRF) is a prevalent and distressing symptom experienced by patients during cancer therapy. One proposed mechanism for the development of fatigue is the increased secretion of proinflammatory cytokines and/or the development of anemia. The major purpose of this pilot study was to investigate the levels of fatigue and cytokines during radiation therapy and determine whether there was a correlation between the two. A secondary purpose was to explore the relationships among hemoglobin values, cytokines, and fatigue. Participants included 15 women diagnosed with uterine canc

Abstract:

Cracked cross-beam connections made of thin-walled rectangular hollow sections (RHS) are repaired with carbon fiber-reinforced polymer (CFRP) sheets. Constant amplitude fatigue experiments are conducted on the repaired specimens. A pilot test is conducted on a T-connection of square hollow sections (SHS) to explore the effective method of applying CFRP. Due to the peeling effect at the corner region of the SHS-to-SHS connection, early debonding happens in the pilot test that only results in a slight extension in fatigue life. In the following experiments of repairing RHS-to-RHS cross-beam conn

Abstract:

Abstract Introduction Previously, combined data analyses of four pilot fatigue monitoring studies including 237 pilots flying long-haul and ultra-long range (ULR) flights found no association between pilots’ actigraphic sleep in flight and psychomotor vigilance task (PVT) performance at top-of-descent (TOD; beginning of the landing phase of flight). The present study aimed to determine whether measures of in-flight sleep recorded with polysomnography (PSG) are more sensitive predictors of pilots’ PVT performance near TOD than actigraphic measures. Methods Data were re-analysed from 41 Singapor
