Système et procédé pour identifier des régions de l'espace aérien comportant des cristaux de glace à l'aide d'un système de radar météorologique embarqué

摘要

Systems and methods of detecting type I ice crystals using an aircraft's onboard weather radar system (210) are disclosed. An exemplary embodiment identifies radar returns having a return level signal strength less than a radar return sensitivity threshold level, determines if at least one of a weather condition and a flight condition concurrently exists with the identified radar returns having the return level signal strength less than the radar return sensitivity threshold level, and identifies a region of airspace potentially having type I ice crystals when the at least one of the weather condition and the flight condition concurrently exists with the identified radar returns having the return level signal strength less than the radar return sensitivity threshold level.
