FIELD: aeronautical engineering.
SUBSTANCE: proposed method consists in measuring the vertical acceleration and indicated barometric altitude by means of static pressure sensor; vertical velocity is obtained through integration of difference of vertical acceleration and acceleration correction; barometric altitude is obtained through integration of difference of vertical velocity and velocity correction; difference between calculated barometric altitude and indicated barometric altitude is used for calculation of said corrections; vertical velocity is multiplied by unitless multiplier equal to ratio of air temperature by standard atmosphere calculated by magnitude of barometric altitude to measured temperature of air.
EFFECT: enhanced accuracy of determination of barometric altitude and vertical velocity under off-standard conditions of flight.
