categorized according to the cognitive processes involved towards the goal of the action and according to whether they are related to planning or execution of the activity. Description Actions by human operators can human error in aviation safety 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 define human error in aviation 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, the person’s

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 http://www.skybrary.aero/index.php/Human_Error_Types the safest methods of getting around our planet. But still human error related accidents occur. What is human error? Errare Humanum Est- To Err is Human Definition “Planned actions that fail to achieve their desired consequences without the intervention of some chance or unforeseeable agency” (Reason, 1990, p.17). Types of human error The simplest catergorisation of human error would be to split them into errors of omission or commission (Kern, 1998). Omission - Errors http://aviationknowledge.wikidot.com/aviation:human-error-in-aviation of omission occur when crew members fail to carryout a required task. Commision - Errors of commission occur when crew members carryout a task incorrectly or do something that is not required. Later researchers further differentiated human error as (Strauch, 2004: Reason, 1990); Slips - Which occur as the result of minor errors of execution. Lapses - Which occur when a pilot becomes distracted and doesn’t complete a task or omits a step whilst performing it. Mistakes - Which occur when actions conform to an inadequate plan. Violations - Which occur where actions deviate from safe procedures standards or rules, be they deliberate or erroneous. Antecedents to human error Reason (1990) also affirmed the idea that the operators, those who commit errors, do not do so in a vacuum. For instance pilots may be consciously attempting to perform perfectly, but human errors can still coccur. This is because other factors, or antecedents, can influence the operator’s performance (Strauch, 2004). These antecedents can include; Other operators, The environment, The equipment being used, National cultures, Organisational cultures. Errors in Aviation There are three main areas in aviation, of interest to human factors professionals and managers who wish to understand and reduce human error. Pilot or Flightdeck error. Air traffic Control error. Maintenance Error Managing Error in Aviation Traditional ideas Early psychological researchers regard

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
