With those opening remarks, we believe that: - with reference to commercial aviation the immediate concern is efficiency - (see “green sector” of Standardized Geometric Application of CA- figure 1-21), i.e., the commercial flight operations require aeronautical equipments that work with lower costs. Necessarily, both results must be reached by observing the “flight safety”. It means to say in case of “air operations” that the expected results will be: sometimes of “efficiency” and/or sometimes of “effectiveness”.
In “aviation” the results of efficiency and of effectiveness are reached in different ways due to the type of employment of aeronautical equipments. In a broader concept it is said that “economicity” is the practical and systematic administration of operations from an entity, project or public company, ensuring minimum operational costs for its functions assigned may be performed efficiently and/or effectively. Notice that the idea of “well manage” is directly linked to labor, time, money, and others, regarding the activity. Therefore, refers to the correct management of the means in all activities, such as commerce, industry, services, governmental institutions and/or organizations, etc., because the activity must be done at the lowest cost and, thus, achieve its goal. It is used to mean the reliable and economical operations of any activity, and so on, with the least possible cost.
The word “economicity”, considered neologism in some languages, translates the quality of everything that is economical.

Then, the explain for continuous need using wind tunnels and/or lift software support. Up to now the calculation of power plant to be installed in an aircraft is done empirically, despite all aeronautical knowledge, technical and scientific resources available. In addition to providing knowledge to be added to existing methodologies, this theory reveals for builders and operators of high-power plant aircrafts a simple secret to having an aeronautical design in terms of desirable "cost x benefit" (economicity relation), considering CA ranging from 1.33 to 6.89 - originated from the vision of "energy per mass”.
