They are categorized according to the cognitive processes involved towards the goal of the action and according to whether they are related to planning or execution human error in aviation safety of the activity. Description Actions by human operators can fail to achieve their goal in two different ways: The actions can go as planned, but the plan can be inadequate, or the plan can be satisfactory, but the performance can still be deficient (Hollnagel, 1993). Errors can be broadly distinguished in two categories: Category 1 - A person intends to carry out

an action, the action is appropriate, carries it out incorrectly, and the desired goal is not achieved. - An execution failure has occurred. Execution errors are called Slips and Lapses. They result from failures in the execution and/or storage stage of an action sequence. Slips relate to observable actions and are commonly associated with attentional or perceptual failures. Lapses are more internal events and generally involve failures of memory. Category 2 - A person intends to carry out an action, does so correctly, the action is inappropriate, and the desired goal is not achieved - A planning failure has occurred. Planning failures are Mistakes. “Mistakes may be defined as deficiencies or failures in the judgmental and/or inferential processes involved in the selection of an objective or in the specification of the means to achieve it.” (Reason, 1990). Execution errors correspond to the Skill based level of Rasmussen’s levels of performance (Rasmussen 1986), while planning errors correspond to the Rule and Knowledge-based levels (see Figure 1) Figure 1: execution and planning failures adapted from Rasmussen Slips and Lapses In a familiar and anticipated situatio

The study of absent-mindedness in everyday life provides ample documentation and categorization of such aspects of behavior. While human error is firmly entrenched in the classical approaches to accident investigation and risk assessment, it has no role in newer approaches such as resilience engineering.[6] Categories[edit] There are many ways to categorize human error.[7][8] exogenous versus endogenous (i.e., originating outside versus inside the individual)[9] situation assessment versus response planning[10] and related distinct

Human Error To this day the http://all-things-aviation.blogspot.com/2010/08/human-error-in-aviation-introduction.html majority of aviation accidents are attributed in some way to some form of human error. Surprising when you consider all the effort and expense put into management, research, training and the development of new technologies such as automation. Yes, safety has vastly improved over the last 50 years, making flying one of the safest methods of getting around our planet. But still human error related accidents occur. For those interested in safety in aviation, human error from pilots and trainers to managers and human factors researchers, a good understanding of what human error is and how it can manifest itself as an aviation accident is fundamental. What is human error? Errare Humanum Est- To Err is Human Early psychological researcher Sigmund Freud saw error as being a behavioural artefact of unconscious drives within a persons mind (Strauch, 2004). He regarded people who erred as being less effective, a theory that human error in tainted early research on human error. Certain people were seen as being ‘accident prone' simply because of particular traits they displayed. But later research showed these ideas to be flawed. Researchers such as Donald Norman and Jens Rasmussen based their research on the cognitive and motor aspects of error and also reflect on the setting in which errors occur (Strauch, 2004). Indeed Norman differentiated errors into slips and mistakes, with slips being errors of execution generated by schemas, experiences, knowledge and memories, whilst he classified mistakes as errors relating to actions or decisions. Rather than using the terms slip and mistake, Kern (1998) prefers the idea that there are errors of omission or commission. Errors of omission occur when crew members fail to carryout a required task. For example the NTSB investigation into American Airlines flight 1420, which overshot the end of the runway at Little Rock, Arkansas, in June1999, showed that a major contributor to the accident was the crew's failure to arm the MD-80's ground spoilers, which are designed to dissipate lift and improve braking (Dismukes, Berman & Loukopoulos, 2007). An error of commission occurs when a crew member carries out some task incorrectly or perhaps does something that is not required. The crash of Southwest Airlines flight 1455 was attributed to the crew's execution of the approa
