Abstract
The International Civil Aviation Organization indicates the need to confirm the ADS-B data. The ADS-B messages include information about the horizontal and vertical location. Information about the altitude of an aircraft in civil aviation is of great importance. The article proposes a modified methodology for confirming ADS-B data when performing flights on local airlines, which allows us to estimate and compare the geometric and barometric altitude of aircraft flight transmitted in a standard ADS-B message. The proposed modification of the method consists is correcting the temperature values, using the full barometric Laplace formula, taking into account the ADS-B quality parameters. In a level flight, with no ground velocity vector data, temperature is corrected using the airspeeds (TAS, IAS) transmitted in the ADS-B message. The method uses a maximum permissible error of 90 m. It is also proposed to determine the air temperature according to geometric and barometric altitude data transmitted in the standard ADS-B message. The determination of air temperature at altitudes involves the use of the ADS-B data from the aircraft that completed take-off. To determine the temperature according to the data of the aircraft completed landing, statistics of data from several aircraft is needed.
