according to whether they are related to planning or execution of the activity. Description Actions by human operators can fail to achieve their goal in two different ways: The actions can go as planned, but the plan human error in aviation maintenance 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 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 human error in aviation statistics 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 intentions were correct, but the execution of the action was flawed - done incorrectly, or not done at all. This distinction, between being done incorrectly or not at all, is another important discriminator. When the appropriate action is carried out incorrectly, the error is classified as a slip. When the action is simply omitted or not carrie

Blue line shows the nominal http://www.skybrary.aero/index.php/Human_Error_Types Las Vegas course, while green is a typical course from Boulder. The pilot inadvertently used the Boulder outbound course instead of the appropriate Las Vegas course. Maraba Airport Belem Airport Location of the crash landing after running out of fuel and departure/destination airports of the Varig Flight 254 (navigational error). Runway collision caused by taking the wrong taxiing route https://en.wikipedia.org/wiki/Pilot_error (red instead of green), as control tower had not given clear instructions. The accident occurred in thick fog. The Tenerife airport disaster now serves as a textbook example.[1] Due to several misunderstandings, the KLM flight tried to take off while the Pan Am flight was still on the runway. The airport was accommodating an unusually great number of large aircraft, resulting in disruption of the normal use of taxiways. The 3p design altimeter is one of the most prone to misreading by pilots (a cause of the UA 389 and G-AOVD crashes). Pilot error (sometimes called cockpit error) is a term once used to describe a decision, action or inaction by a pilot or crew of an aircraft determined to be a cause or contributing factor in an accident or incident. The term included mistakes, oversights, lapses in judgment, gaps in training, adverse habits, and failures to exercise due diligence in a pilot's duties. The causes of pilot error are due to psychological and physiological human limitations, and various forms of threat and erro
those with 10 or more passengers and one or more fatalities. Military and private aircraft and helicopters were excluded. Where there were multiple causes, the most prominent cause was used. The category of pilot error includes those accidents in which weather or a http://www.planecrashinfo.com/cause.htm mechanical fault was a strong contributing factor to the pilot error.
