FIELD: flying vehicles. SUBSTANCE: technique consists in measurement of technical parameters in process of flight tests of specimen of new agricultural equipment and in their comparison with technical parameters of specimen of agricultural equipment tested before. In process of realization of technique following technical parameters are measured during flight tests of each specimen: density of substance precipitated on unit of area, flight weight of flying vehicle during flight over recording line, second flow rate of working fluid, fluid pressure across outlet of pump, air temperature at moment of operational coverage of specimen of new equipment. Reduced density of substance precipitated on unit of area, reduced consumption of working fluid per second and reduced width of operational coverage are found per each new specimen of equipment. EFFECT: generation of objective evaluation of equipment.
