Summary
A new fatigue questionnaire for Chinese civil aviation pilots shows acceptable reliability and validity. It helps identify fatigue differences between international and domestic flights, aiding flight safety management.
Area of Science:
- Aviation Safety
- Occupational Health
- Psychometrics
Background:
- Fatigue risk management is critical for aviation safety.
- Developing effective fatigue assessment tools for pilots is essential.
- Chinese civil aviation pilots face unique operational demands.
Purpose of the Study:
- To develop a comprehensive fatigue risk management indicators system.
- To create and validate a fatigue questionnaire for Chinese civil aviation pilots.
Main Methods:
- A fatigue questionnaire was administered to 74 male Chinese civil aviation pilots.
- Statistical analyses included Cronbach's alpha for internal consistency and Pearson's correlation.
- Student's t-test was used to compare fatigue scores between pilot groups.
Main Results:
- The developed fatigue questionnaire demonstrated acceptable internal consistency reliability and construct validity.
- Significant differences in fatigue scores were observed between international and domestic flight pilots.
- International pilots using sleep aids reported poorer sleep quality; long-duration flights impacted circadian rhythms.
Conclusions:
- The fatigue questionnaire is a reliable tool for assessing fatigue in Chinese civil aviation pilots.
- Findings provide a basis for a fatigue risk management system in civil aviation.
- Understanding fatigue drivers like flight type and circadian disruption is key to enhancing pilot well-being and flight safety.

861
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

01:21Pilot and Numeric Relaying
496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:24Muscle Recovery and Fatigue
4.3K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:22Fatigue Strength of Concrete
578
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
