    摘要: A method of determining the ground speed or drift angle of an aircraft is described. It is determined whether or not a weather threshold has been met based on returns of a radar beam which is pulse compressed in a first scan. If the weather threshold is determined to have not been met, a ground speed or drift angle of the aircraft is determined based on Doppler processing of radar beam returns of a radar beam in a second scan. If the weather threshold has been met, a bottom radar beam is directed lower to the ground, and a ground speed or drift angle of the aircraft is determined based on Doppler processing returns of the bottom radar beam directed lower to the ground. A corresponding radar system is also described.

    摘要: Systems and methods for displaying weather data relating to weather near an aircraft are provided. A method includes generating a three-dimensional weather profile of the weather near the aircraft based on reflectivity data from radar returns of a weather radar system of the aircraft. Generating the three-dimensional weather profile includes estimating weather data above a freezing layer height using a function that is based on a rate of reduction in reflectivity above the freezing layer. The method further includes transmitting weather display data to a display device, the weather display data being configured to cause the display device to display a visual representation of the three-dimensional weather profile.

    摘要: A weather radar system for an aircraft is provided. The weather radar system includes processing electronics configured to process radar return data to identify a weather cell, to store information related to the identified weather cell in a database, to receive a selection of an identified weather cell from a user interface, to receive the information related to the selected weather cell from the database, and to cause the information to be displayed textually on a display in response to the received selection.

    摘要: A method for indicating readiness of a predictive windshear system on an aircraft is provided. The method includes determining whether a windshear system is in a ready state and providing a first output that causes an indication of the ready state, the ready state being responsive to the windshear system being ready to detect a windshear event. Determining whether the windshear system is in the ready state includes comparing a first time until a first parameter reaches a first value with a second time for initialization of the windshear system and determining that the windshear system is ready to detect the windshear event in response to the first time being greater than the second time.
