The human factor in the aeronautical environment has been analyzed in the most frequent cases of flight crew errors and air traffic control. The human factor directly causes many aviation accidents. Studies show that 80% of aviation errors involve human factors. If not detected in time, it can cause accidents. Awareness of the role of the human factor leads to an improvement in the quality of professional and personal activity, to an environment that facilitates the continuous safety of people or aircraft, and to more involvement and responsibility. Reducing the number of errors offers various benefits, from reducing accidents at work to decreasing the number of significant events. Most of the time the human factor is approached in relation to ways of mitigating the risk, preventing the development of problems. The paper aims to highlight multiple interpretations of the human factor in order to become aware of its value and complexity. [ABSTRACT FROM AUTHOR]

Abstract: This paper reports the experimental analysis of a mini Vapor Cycle System (VCS) for electronic thermal management in avionic applications. The water cooled miniature scale refrigeration system uses R134a as working fluid and implements a new concept oil-free linear compressor prototype. In the range of operating test conditions investigated the pressure ratio varies from 1.54 to 3.75, the cooling capacity of the system varied from 37 W to 374 W, while the coefficient of performance (COP) ranged between 1.04 and 5.80. Particular attention was dedicated to the cold plate design, which had to meet the requirements established by aeronautical standards. The cold plate was equipped with 15 thermocouples in order to monitor the wall temperature distribution. The suitability and feasibility of the proposed cold plate for electronic thermal management in an aeronautical environment is critically discussed, based on the experimental results.
