Aire-tech Aviation Repairs Human Factors Quiz

Protecting worker health, comfort, and well-being is important because it directly affects their performance and safety. When workers are healthy and comfortable, they are more likely to perform their tasks efficiently and effectively. They are also less likely to make errors or be involved in accidents. By prioritizing worker well-being, employers create a conducive work environment that promotes productivity and minimizes the risks associated with poor health and discomfort. Therefore, the statement that protecting worker health, comfort, and well-being results in improved task performance and a reduction in errors and accidents is true.

Human Factors is essential in system design and development because it focuses on optimizing the interaction between humans and technology. It considers the capabilities, limitations, and needs of users to ensure that the system is user-friendly, efficient, and safe. By incorporating human factors, designers can enhance the usability, accessibility, and overall user experience of the system, leading to increased user satisfaction and productivity. Neglecting human factors can result in poor system performance, user frustration, and potential safety hazards. Therefore, it is crucial to prioritize human factors in the design and development process.

The statement "THE GREATEST HAZARD TO AIRCRAFT IS HUMANS" is true. Humans pose a significant risk to aircraft safety due to their potential for errors and negligence. Human factors such as pilot error, air traffic controller mistakes, and maintenance errors can lead to accidents and incidents. Additionally, human behavior on the ground, such as unauthorized intrusion into restricted areas, can also pose a threat to aircraft operations. Therefore, it is accurate to say that humans are the greatest hazard to aircraft.

Human Factors is best applied "Early and often" because it refers to the practice of incorporating human factors considerations throughout the design and development process of a product or system. By considering human factors early in the design phase, potential issues related to usability, efficiency, and safety can be identified and addressed before they become costly or difficult to fix. Additionally, involving users and conducting usability testing at various stages of development allows for iterative improvements and ensures that the final product meets the needs and preferences of the target users.

From the presentation, we learned that an "active error" is a specific individual activity that is an obvious event. This means that an active error refers to a clear and easily identifiable action or behavior performed by an individual. It is not a vague or ambiguous occurrence, but rather something that can be easily recognized and understood. Therefore, the statement "an 'active error' is a specific individual activity that is an obvious event" is true based on the information provided in the presentation.

A team differs from a "group" in that it is individually and collectively accountable. This means that each member of the team is responsible for their own actions and contributions, as well as the overall success or failure of the team. In contrast, a group may not have the same level of accountability and may not be as focused on achieving a common goal. The concept of individual and collective accountability helps to foster a sense of ownership, collaboration, and motivation within a team.

Anthropometrics is the study of measurement of human physical attributes. It involves collecting data on various physical characteristics such as height, weight, body proportions, and other anatomical features of individuals or populations. This field of study helps in understanding human variations and provides valuable information for designing products, spaces, and services that are tailored to the needs and abilities of different individuals.

The given statement suggests that human factors error was responsible for approximately 45% of international accident cause factors in 2007. This implies that a significant number of accidents can be attributed to human error, highlighting the importance of addressing and mitigating such errors to improve safety.

A VIOLATION IS A SERIOUS INTENTIONAL MISTAKE

The correct answer is lack of communication, lack of teamwork, and lack of knowledge. These three factors are known as the "Dirty Dozen" and are commonly identified as major contributors to human errors in various industries. Lack of communication can lead to misunderstandings and misinterpretations, lack of teamwork can result in coordination issues and conflicts, and lack of knowledge can lead to incorrect decisions and actions. These factors highlight the importance of effective communication, teamwork, and continuous learning in preventing human errors.

Over lubrication is not on the list of top maintenance errors in the last 3 years. This means that it is not considered as one of the common mistakes or problems that occur during maintenance. The other options - incorrect installation, cross connections, and forgotten tools and parts - are all mentioned as being on the list of top maintenance errors, indicating that they are more commonly encountered issues.

The application of human factors to machine/system design aims to take advantage of the strengths and abilities of humans while also addressing their limitations. By capitalizing on human capabilities, such as perception, cognition, and problem-solving skills, the design can enhance user performance and efficiency. At the same time, compensating for human limitations, such as memory constraints, attentional limitations, and error-proneness, can help reduce errors, improve safety, and enhance overall system usability. Therefore, both capitalizing on human capabilities and compensating for human limitations are important aspects of designing systems that are user-friendly and effective.

Crew Resource Management (CRM) is defined as the effective use of all resources, including human and other aviation system resources. This means that CRM focuses on managing and utilizing all available resources in order to enhance safety and efficiency in aviation operations. It involves effective communication, teamwork, decision-making, and problem-solving skills among the crew members. By utilizing CRM principles, the crew can effectively coordinate and utilize all available resources to ensure safe and successful flight operations.

The three-pronged approach to "error management" in CRM includes avoiding errors, trapping errors, and mitigating errors. However, eliminating errors is not part of this approach. Eliminating errors completely may be an ideal goal, but it is not always possible to achieve. Instead, the focus is on preventing errors, detecting and addressing them when they occur, and minimizing their impact through mitigation strategies.

IT IS NOT TRUE THAT ANYONE CAN PERFORM HUMAN FACTORS.
