ABSTRACT
The very characteristics of commercial aviation, highly complex systems and grave potential of their contingencies impose upon the organizations that work in this field the quality of high-risk organization. The definition of high-risk organization puts reliability as a more pressing problem than efficiency. As technology improves, the potential for safety increases, but this isn't fully used for improvements in safety. The demands of efficiency, that is, improvements in speed, altitude, manoeuvrability, fuel consumption, reduction in training cycles and the possibility of operating in any meteorological conditions, among others, are present. The action of the low-cost airlines and the impact of their existence and practices on the traditional operators are significant in the search for efficiency. However, the current situation allows an easy analogy with the functioning of an engine. More power can be extracted from an engine by introducing a turbo compressor and increasing pressure.
