Pilot Error
In aviation, pilot error generally refers to an action or decision made by a Aircraft pilot#Airline, pilot that is a substantial contributing factor leading to an Aviation accidents and incidents, aviation accident. It also includes a pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. The Chicago Convention on International Civil Aviation, Chicago Convention defines the term "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 "pilot error" does not include deliberate crashing (and such crashes are not classified as accidents). 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 ...

Cognitive Overload
In cognitive psychology, cognitive load is the effort being used in the working memory. According to work conducted in the field of instructional design and pedagogy, broadly, there are three types of cognitive load: * ''Intrinsic'' cognitive load is the effort associated with a specific topic. * ''Germane cognitive load refers to the work put into creating a permanent store of knowledge (a schema).'' * ''Extraneous'' cognitive load refers to the way information or tasks are presented to a learner. However, over the years, the additivity of these types of cognitive load has been investigated and questioned. Now it is believed that they circularly influence each other. Cognitive load theory was developed in the late 1980s out of a study of problem solving by John Sweller. Sweller argued that instructional design can be used to reduce cognitive load in learners. Much later, other researchers developed a way to measure perceived mental effort which is indicative of cognitive load. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Proximity Warning System
A Ground Proximity Warning System (GPWS) is a system designed to alert pilots if their aircraft is in immediate danger of flying into the ground or an obstacle. The United States Federal Aviation Administration (FAA) defines GPWS as a type of terrain awareness and warning system (TAWS). More advanced systems, introduced in 1996, are known as enhanced ground proximity warning systems (EGPWS), a modern type of TAWS. History In the late 1960s, a series of controlled flight into terrain (CFIT) accidents took the lives of hundreds of people. A CFIT accident is one where a properly functioning airplane under the control of a fully qualified and certified crew is flown into terrain, water or obstacles with no apparent awareness on the part of the crew.Note: Original text copied from U.S. FAA Circular AC23-1.

Airborne Collision Avoidance System
An airborne collision avoidance system (ACAS, usually pronounced as ''ay-kas'') operates independently of ground-based equipment and air traffic control in warning pilots of the presence of other aircraft that may present a threat of collision. If the risk of collision is imminent, the system recommends a maneuver that will reduce the risk of collision. ACAS standards and recommended practices are mainly defined in annex 10, volume IV, of the Convention on International Civil Aviation. Much of the technology being applied to both military and general aviation today has been undergoing development by NASA and other partners since the 1980s. A distinction is increasingly being made between ACAS and ASAS (airborne separation assurance system). ACAS is being used to describe short-range systems intended to prevent actual metal-on-metal collisions. In contrast, ASAS is being used to describe longer-range systems used to maintain standard ''en route'' separation between aircraft ( ho ...

General Aviation
General aviation (GA) is defined by the International Civil Aviation Organization (ICAO) as all civil aviation aircraft operations except for commercial air transport or aerial work, which is defined as specialized aviation services for other purposes. However, for statistical purposes, ICAO uses a definition of general aviation which includes aerial work. General aviation thus represents the " private transport" and recreational components of aviation, most of which is accomplished with light aircraft. Definition The International Civil Aviation Organization (ICAO) defines civil aviation aircraft operations in three categories: General Aviation (GA), Aerial Work (AW) and Commercial Air Transport (CAT). Aerial work operations are separated from general aviation by ICAO by this definition. Aerial work is when an aircraft is used for specialized services such as agriculture, construction, photography, surveying, observation and patrol, search and rescue, and aerial adver ...

Commercial Aviation
Commercial aviation is the part of civil aviation that involves operating aircraft for remuneration or hire, as opposed to private aviation. Definition Commercial aviation is not a rigorously defined category. All commercial air transport and aerial work operations are regarded as commercial aviation, as well as some general aviation flights. An aircraft operation involving the transportation of people, goods, or mail for payment or hiring is referred to as commercial air transport. Both scheduled and unscheduled air transport operations are included. An aircraft used for specialized services including agriculture, construction, photography, surveying, observation and patrol, search and rescue, advertising, etc. is referred to as aerial work. General aviation includes commercial activities such as flight instruction, aerial work, and corporate and business aviation, as well as non-commercial activities such as recreational flying. Most commercial aviation activities require ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pilot (aeronautics), pilots and Aircrew, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indonesia AirAsia Flight 8501
Indonesia AirAsia Flight 8501 was a scheduled international passenger flight operated by Indonesia AirAsia from Surabaya, Java, Indonesia, to Singapore. On 28 December 2014, the Airbus A320-216 flying the route crashed into the Java Sea, killing all 162 of the people on board. When search operations ended in March 2015, only 116 bodies had been recovered. This is the first crash and only fatal accident involving Indonesia AirAsia. In December 2015, the Indonesian National Transportation Safety Committee (KNKT or NTSC) released a report concluding that a non-critical malfunction in the rudder control system prompted the captain to perform a non-standard reset of the on-board flight control computers. Control of the aircraft was subsequently lost, resulting in a stall and uncontrolled descent into the sea. Miscommunication between the two pilots was cited as a contributing factor.

Human Error
Human error is an action that has been done but that was "not intended by the actor; not desired by a set of rules or an external observer; or that led the task or system outside its acceptable limits".Senders, J.W. and Moray, N.P. (1991) Human Error: Cause, Prediction, and Reduction'. Lawrence Erlbaum Associates, p.25. . Human error has been cited as a primary cause and contributing factor in disasters and accidents in industries as diverse as Nuclear and radiation accidents and incidents, nuclear power (e.g., the Three Mile Island accident), Pilot error, aviation, List of spaceflight-related accidents and incidents, space exploration (e.g., the Space Shuttle Challenger disaster and Space Shuttle Columbia disaster), and Medical error, medicine. Prevention of human error is generally seen as a major contributor to Data integrity, reliability and safety of (complex) systems. Human error is one of the many contributing causes of risk events. Definition Human error refers to somethi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altimeter
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water. Types Pressure altimeter Sonic altimeter In 1931, the US Army Air corps and General Electric together tested a sonic altimeter for aircraft, which was considered more reliable and accurate than one that relied on air pressure when heavy fog or rain was present. The new altimeter used a series of high-pitched sounds like those made by a bat to measure the distance from the aircraft to the surface, which on return to the aircraft was converted to feet shown on a gauge inside the aircraft cockpit. Radar altimeter A radar altimeter measures altitude more directly, using the time taken for a radio signal to reflect from the surface back to the aircraft. Alternatively, Frequency Modulated Continuous-wave radar can be used. The greater th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all General aviation, private, Military aviation, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, AT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Conditions
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.
