Accuracy Of Aircraft Barometric Altimeters

Jan Čižmár, Miloš Andrle


The article deals with methodical and instrumental errors of the aircraft barometric measurement of the flight altitude by means of mechanical altimeters and air data computers. The calculation of the methodical errors has been carried out both for selected values of the declension from the standard values, and for three real meteorological situations on the base of which the methodical accuracy of the barometrical altimeter and the air data computer has been compared.
