A method of verifying aircraft position information based on ADS-B messages includes receiving an ADS-B message indicating an identifier of an aircraft and indicating a position of the aircraft. The method includes accessing a tamper-resistant distributed public ledger of authenticated flight plan data to determine whether flight plan data associated with the identifier is stored in the tamper-resistant distributed public ledger. The method includes, conditioned upon a determination that the flight plan data is stored in the tamper-resistant distributed public ledger, comparing the position to a flight path indicated by the flight plan data. The method includes selecting a characteristic of an icon corresponding to the aircraft based on a determination whether the position corresponds to the flight path. The method further includes displaying, on a display device and based on the characteristic, the icon at a location corresponding to the position.
