and latent failures, including unsafe acts, preconditions for unsafe acts, unsafe supervision, and organizational influences.[1] It is a comprehensive human error framework, that folded Reason's ideas into the applied setting, defining 19 causal categories within four levels of human failure.[3] Contents 1 HFACS Taxonomy 1.1 HFACS Level 1: Unsafe Acts 1.2 HFACS Level 2: Preconditions for Unsafe Acts 1.3 human factors analysis tools HFACS Level 3: Unsafe Supervision 1.4 HFACS Level 4: Organizational Influences 2 See also 3 References HFACS Taxonomy[edit] The HFACS taxonomy describes four levels within Reason's model and are described below.[4][5] HFACS Level 1: Unsafe Acts[edit] The Unsafe Acts level is divided into two categories - errors and violations - and these two categories are then divided into subcategories. Errors are unintentional behaviors, while violations are a willful disregard of the rules and regulations. Errors Skill-Based Errors: Errors which occur in the operator’s execution of a routine, highly practiced task relating to procedure, training or proficiency and result in an unsafe a situation (e.g., fail to prioritize attention, checklist error, negative habit). Decision Errors: Errors which occur when the behaviors or actions of the operators proceed as intended yet the chosen plan proves inadequate to achieve the desired end-state and results in an unsafe situation (e.g. exceeded ability, rule-based error, inappropriate procedure). Perceptual Errors: Errors which occur when an operator's sensory input is degraded and a decision is made based upon faulty information. Vio

Metadata Show full item record Abstract The Aviation industry is a highly complex and dynamic domain. Over all, commercial flight crews consistently operate at a very high level of reliability and safety. Yet, accident records show there is a disparity between the flight crews that operate under Title 14, Part 121 of the human error Code of Federal Regulations (CFR) and those that operate under Part 135 of that same code. In their daily operations, the performance of both groups are shaped by the complexity of this environment, their interactions with the system and their own personal, as well as team skill sets. However, the flight crews of part 135 operators consistently make more errors, ranging from procedural, tactical human factors analysis and regulatory. These factors have been studied from a broad theoretical framework using many different perspectives, but a conclusive explanation for the disparity in the accident rates between the part 121 and 135 operators remains elusive. One common methodology of error classification is analyzing a database of accident and incident information to identify the errors that pilots make in specific operational areas within the aviation system. In the last decade, researchers have developed a number of error classification schemes, and the reports of their findings are abundant in the literature describing the taxonomy of human errors in the aviation system. However, there is little research that correlates the flight training methodology that is designed to mitigate these errors, to the error classification schemes commercial air carriers currently use. Furthermore, there is no research that focuses on the classification errors made by pilots or flight crews that operate under the part 135 regulations. This thesis examines some of the most influential literature that has shaped the development of systems designed to analyze and encode aviation accidents and incidents, as well as systems to classify human error in the aviation system.
