Full Text Available In this article the comparative economic-mathematical analysis of size of profit per a flight hour on use at the avia- tion-chemical works (ACW of two types of super light aircraft X-32 “Bekas” and a glider MD-50S which are widely used when cultivating farmland nowadays. The list of indicators which are used while carrying out the comparative technical and economic analysis of considered ultralights is given at the beginning of the article. Further their numerical values nec- essary for computations are given. The mathematical formula for calculation with use of the given data of profit on carrying out ACW with use of the considered models of the aircraft equipment is presented. Values of profit are calculated by means of the tabular Microsoft Excel editor for various values of cultivated farmland length and distance of approach from airfield to the cultivated plot. The applied values of cultivated farmland length lie in the range from 0.5 to 10 kilometers, and ap-proach distances vary from 0.5 to 2 kilometers respectively. Calculations are executed for each of two compared ultralights and results are given in a tabular form respectively. On the basis of the analysis of the obtained tabular data conclusions are drawn under what values of input and variables in the form of farmland length and distance of approach profit margin for each of two ultralights will be larger or smaller in comparison with each other. In the final part of article total conclusions about the most preferable ultralight of two compared for operation in fields of various configuration during ACW are drawn. At the end recommendations to the aviation enterprises about application of the most expedient option of ultralight for obtaining bigger profit margin on carrying out ACW.
