So much so that even a specific terminology known as 'ergonomics' meaning the 'Human Engineering' is being used to denote the field of Human Factor. Ergonomics is commonly thought of as how companies design tasks and work areas to maximize the efficiency and quality of their employees' work. However, ergonomics comes into everything which involves people, like sports and leisure, health and safety should all embody ergonomics principles if well designed. As already mentioned, some three out of four accidents have resulted from less than optimum human performance. This has commonly been classified as "pilot error". The term "pilot error" is of no help in accident prevention. In fact, it is often counterproductive because, although this term may indicate WHERE in the system a breakdown occurs, it provides no guidance as to WHY it occurs. An error attributed to humans in the system may have been design-induced or stimulated by inadequate training, badly designed procedures or the poor concept or layout of checklists or manuals. Further, the term "pilot error" allows concealment of the underlying factors which must be brought to the fore if accidents are to be prevented. Most often it is thought that human factors are related to flight crews only. However, now it has been established that human factors problems affect on the performance of maintenance people and other ground staff also. Aviation Safety The best way to illustrate the effect on safety of a lack of proper application of Human Factors is through the example of accidents. A few accidents in which aspects of Human Factors are relevant are described here as examples. (a) In December 1972 – an L1011 crashed in the Florida Everglades and a B-737 crashed at Midway Airport in Chicago. In the first case, duties were not properly allocated (c) UPES, Not for Reproduction/ Sale

In the second case, the captain – as a leader – did not properly manage the resources which were available to him. (b) In 1974, a B-707 crashed during approach at Pago-Pago in Samoa, with a loss of 96 lives. A visual illusion related to the black-hole phenomenon was a cause factor. (c) In 1974, a DC-10 crashed after takeoff because a cargo door failed (it opened and blew out). The force applied by a cargo handler to close the cargo door, the door design and an incomplete application of a service bulletin were cited as factors. (d) In 1974, a B-727 approaching Dulles Airport in Washington crashed into Mount Weather, with a loss of 92 lives. Lack of clarity and inadequacies in air traffic control procedures and regulations led to the accident. The absence of timely action of the regulatory body to resolve a known problem in air traffic terminology was also listed as a factor.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
