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 define human error in aviation 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 situation people perform a skill-based behaviour. At this level, they can commit skill-based errors (slips or lapses). In the case of slips and lapses,

While typically associated with flight operations, human error has also recently become a major concern in maintenance practices and air traffic management. Boeing human factors professionals work with engineers, pilots, and mechanics to apply the latest knowledge about the interface between human performance and commercial airplanes to help operators improve safety and efficiency in their daily operations. The term "human factors" has grown increasingly popular as the commercial aviation industry has realized that human error, rather than mechanical failure, underlies most aviation accidents and incidents. If interpreted narrowly, human factors is often considered synonymous with crew resource management (CRM) or maintenance resource management (MRM). However, it is much broader in both its knowledge base and scope. Human factors involves gathering information about human abilities, limitations, and other characteristics and applying it to tools, machines, systems, tasks, jobs, and environments to produce safe, comfortable, and effective human use. In aviation, human factors is dedicated to better understanding how humans can most safely and efficiently be integrated with the technology. That understanding

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 human error still human error related accidents occur. For those interested in safety in aviation, 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 human error in drives within a persons mind (Strauch, 2004). He regarded people who erred as being less effective, a theory that 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
