Pilot error (sometimes called cockpit error) is a decision, action or inaction by a pilot of an aircraft determined to be a cause or contributing factor in an accident or incident. Pilot error can be a mistake, oversight, lapse in judgment, or failure to exercise due diligence by pilots during the performance of their duties. The causes of pilot error are due to psychological and physiological human limitations, and various forms of threat and error management have been implemented into pilot training programs to teach crew members how to deal with inherent situations which arise throughout the course of a flight. A broader view of how human factors fit into a system is now considered standard practice by accident investigators when examining the chain of events that led to an accident.〔 ==Description== Usually in an accident caused by pilot error, it is assumed that the pilot in command (captain) makes an error unintentionally. However, an intentional disregard for a standard operating procedure (or warning) is still considered to be a pilot error, even if the pilot's actions justified criminal charges. Pilot error is a decision or action mistake by pilots when there is an emergency. As the commander of the airplane, pilot is always regarded to be one of the most important factors because the decision of the pilot which determine everything on the plane,can be affected by countless external elements .Although these limitations, the findings state the value that analyses of accident patterns might have for the improvement of passengers safety. The pilot may be a factor even during adverse weather conditions if the investigating body deems that the pilot did not exercise due diligence. The responsibility for the accident in such a case would depend upon whether the pilot could reasonably know of the danger and whether he or she took reasonable steps to avoid the weather problem. Flying into a hurricane (for other than legitimate research purposes) would be considered pilot error; flying into a microburst would not be considered pilot error if it was not detectable by the pilot, or in the time before this hazard was understood. Some weather phenomena (such as clear-air turbulence or mountain waves) are difficult to avoid, especially if the aircraft involved is the first aircraft to encounter the phenomenon in a certain area at a certain time. Placing pilot error as a cause of an aviation accident has often been controversial. For example, the NTSB ruled that the crash of American Airlines Flight 587 was because of the failure of the rudder, which was caused by "unnecessary and excessive rudder pedal inputs" on the part of the co-pilot who was operating the aircraft at the time. Attorneys for the co-pilot, who was killed in the crash, argue that American Airlines' pilots had never been properly trained concerning extreme rudder inputs. The attorneys also claimed that the rudder failure was actually caused by a flaw in the design of the Airbus A300 aircraft and that the co-pilot's rudder inputs should not have caused the catastrophic rudder failure that led to the accident that killed 265 people. Modern accident investigators attempt to avoid the words "pilot error", as the scope of their work is to determine the cause of an accident, rather than apportion blame. Furthermore, any attempt to blame pilots does not consider that they are part of a broader system, which in turn may be at fault for their fatigue, work pressure or lack of training. ICAO and its member states therefore adopted the Reason Model in 1993 in an effort to better understanding the role of human factors in aviation accidents. Thus, pilot error is a major cause of air accidents.During 2004, pilot error was pointed to be the primary reason of 78.6% of disastrous GA (general aviation) accidents, and as the major cause of 75.5% of general aviation accidents in the US.Pilot errors are related to multiple causes.Decision errors can be caused by several factors such as tendencies, biases as well as breakdowns when human proceeds the information coming in. For pilot in aviation, these errors are highly to produce not only errors but also fatalities.〔Foyle, D. C., & Hooey, B. L. (Eds.). (2007). Human performance modeling in aviation.
