Sažetak
Errors that occur in conventional measurement instruments connected to a pitot-static system affect the accuracy and reliability of indicating the basic navigation elements required for the safety of flight. This paper is to present the manner and methods of preparing and implementing experimental measurements in order to determine the stochastic and functional laws of deviation and change in the actual aircraft flying speed with the changes in altitude and airspeed, as well as to determine the influence of the change in air temperature on the measured values of airspeed up to the pressure altitude of 5, 000 m. Using a comparative analysis of parameters measured during the flight by means of a sensor system on a twin-engine turboprop aircraft Antonov AN-32 and by means of a GPS instrument as well as theoretical calculations of pressure obtained in accordance with the measured values, this paper will present the problems of measuring the parameters by a pitot-static system.
