Threat And Error Management
In aviation safety, threat and error management (TEM) is an overarching safety management approach that assumes that pilots will naturally make mistakes and encounter risky situations during flight operations. Rather than try to avoid these threats and errors, its primary focus is on teaching pilots to manage these issues so they do not impair safety. Its goal is to maintain safety margins by training pilots and flight crews to detect and respond to events that are likely to cause damage (threats) as well as mistakes that are most likely to be made (errors) during flight operations. TEM allows crews to measure the complexities of a specific organization's context — meaning that the threats and errors encountered by pilots will vary depending upon the type of flight operation — and record human performance in that context. TEM also considers technical (e.g. mechanical) and environmental issues, and incorporates strategies from Crew Resource Management to teach pilots t ...

Likert Scale
A Likert scale ( , commonly mispronounced as ) is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale) is often used interchangeably with ''rating scale'', although there are other types of rating scales. The scale is named after its inventor, psychologist Rensis Likert. Likert distinguished between a scale proper, which emerges from collective responses to a set of items (usually eight or more), and the format in which responses are scored along a range. Technically speaking, a Likert scale refers only to the former. The difference between these two concepts has to do with the distinction Likert made between the underlying phenomenon being investigated and the means of capturing variation that points to the underlying phenomenon. When responding to a Likert item, respondents specify their level of agreement or disagree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Curse Of Expertise
The curse of knowledge is a cognitive bias that occurs when an individual, who is communicating with other individuals, assumes that the other individuals have the background knowledge to understand. This bias is also called by some authors the curse of expertise. For example, in a classroom setting, teachers have difficulty because they cannot put themselves in the position of the student. A knowledgeable professor might no longer remember the difficulties that a young student encounters when learning a new subject. This curse of knowledge also explains the danger behind thinking about student learning based on what appears best to faculty members, as opposed to what has been verified with students. History of concept The term "curse of knowledge" was coined in a 1989 ''Journal of Political Economy'' article by economists Colin Camerer, George Loewenstein, and Martin Weber. The aim of their research was to counter the "conventional assumptions in such (economic) analyses of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Error Management
Error management theory (EMT) is an extensive theory of perception and cognition biases created by David Buss and Martie Haselton. How humans think and make decisions using heuristics and biases may be embedded in the human brain. Error management training is a related area that uses this theory. The objective of it is to encourage trainees to make errors and encourage them in reflection to understand the causes of those errors and to identify suitable strategies to avoid making them in future. An example of error management theory is the Ebbinghaus–Titchener circles that can illustrate, a person's view of which of the (orange) centre circles is bigger is subjective, and can cause a misinterpretation of reality. That is to say, both circles are the same size but each person may interpret the information presented differently depending on which bias they rely on to make the decision. Various biases in thinking and decision-making have been highlighted by Daniel Kahneman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Error
Pilot error generally refers to an Aviation accidents and incidents, accident in which an action or decision made by the Aircraft pilot#Airline, pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. Chicago Convention on International Civil Aviation, Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of the "pilot error" does not include deliberate crash (and such crash is not an accident). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs to teach crew members how t ...

Accident Classification
Accident classification is a standardized method in accident analysis by which the causes of an accident, including the root causes, are grouped into categories. Accident classification is mainly used in aviation but can be expanded into other areas, such as railroad or health care. While incident report, accident reports are very detailed, the goal of accident classification is to look at a broader picture. By analysing a multitude of accidents and applying the same standardized classification scheme, patterns in how accidents develop can be detected and correlations can be built. The advantage of a standardized accident classification is that statistical methods can be used to gain more insight into accident causation. A good accident classification system * is easy to apply, ideally it is intuitive to use, * covers as many aspects as possible: human performance, organisational issues, technological issues, Threat and error management, * enables the safety experts to recreate th ...

Runway Excursion
A runway excursion is a runway safety incident where an aircraft makes an inappropriate exit from the runway. Runway excursions include runway overruns, where an aircraft is unable to stop before it reaches the end of the runway. Runway excursions can happen because of pilot error, poor weather, or a fault with the aircraft. According to the Flight Safety Foundation, as of 2008, runway excursions were the most frequent type of landing accident, slightly ahead of runway incursion. For runway accidents recorded between 1995 and 2007, 96% of runway accidents and 80% of accidents with fatalities involved runway excursions. Management and prevention Efforts to address runway excursion either focus on preventing runway excursions, or on minimizing the amount of damage or injury caused by a runway excursion. In the latter category, aviation safety regulators may establish standards such as minimum runway safety areas intended to allow adequate time and distance for an aircraft to stop ...

Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, under aircraft pilot, pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending disaster until it is too late. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are not considered CFIT (they are known as ''uncontrolled flight into terrain'' or ''UFIT''), nor are incidents resulting from the deliberate action of the person at the controls, such as acts of terrorism or suicide by pilot. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircraft. CFIT was identified as a cause of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailstrike
In aviation, a tailstrike or tail strike occurs when the tail or empennage of an aircraft strikes the ground or other stationary object. This can happen with a fixed-wing aircraft with tricycle undercarriage, in both takeoff where the pilot rotates the nose up too rapidly, or in landing where the pilot raises the nose too sharply during final approach, often in attempting to land too near the runway threshold. It can also happen during helicopter operations close to the ground, when the tail inadvertently strikes an obstacle. A minor tailstrike incident may not be dangerous in itself, but the aircraft may still be weakened and must be thoroughly inspected and repaired if a more disastrous accident is to be avoided later in its operating life. Protection measures Fixed-wing aircraft with a conventional tail and tricycle undercarriage are vulnerable to tailstrike. Those which require a high angle of attack on takeoff or landing are especially so. They may be fitted with a protect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airlines
An airline is a company that provides air transport services for traveling passengers and freight. Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Czech Republic's Czech Airlines (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has also be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Operating Procedures
A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output, and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations. Some military services (e.g., in the U.S. and the UK) use the term standing (rather than ''standard'') operating procedure, since a military SOP refers to a unit's unique procedures, which are not necessarily standard to another unit. The word "standard" could suggest that only one (standard) procedure is to be used across all units. The term is sometimes used facetiously to refer to practices that are unconstructive, yet the norm. In the Philippines, for instance, "SOP" is the term for pervasive corruption within the government and its institutions. Clinical research and practice In clinical research, the '' International Council for Harmonisation'' (ICH) defines SOPs as "de ...
