Long range weather information display system and method

摘要

A system and method of displaying weather data related to weather for an aircraft can include receiving onboard weather data and external weather data. A vertical weather profile is provided on a display based on the onboard weather data and the external weather data. Display includes a first portion associated with a first range closest to the aircraft and a second portion associated with a second range farthest from the aircraft. First images of weather in the first range are provided on the first portion in response to the onboard weather data and second images of the weather in the second range are provided on the second portion in response to the external weather data. Blended images can be provided on a blended portion between the first range and the second range.

1. A method of displaying weather for an aircraft using an avionic weather radar system, the method comprising:
providing a radar signal via a radar antenna of the avionic weather radar system; receiving weather radar returns associated with the radar signal; receiving onboard weather data derived from the weather radar returns of the weather radar system of the aircraft; receiving external weather data from an external source, the external source being remote from the aircraft via an electronic communications unit; and providing a vertical weather profile of the weather on an electronic display based on the onboard weather data and the external weather data from the external source, wherein the electronic display provides a first portion associated with a first range closest to the aircraft, a second portion associated with a second range, and a third portion associated with a third range farthest from the aircraft, the second range being between the first range and the third range, wherein first images of the weather in the first range are provided on the first portion in response to the onboard weather data without the external weather data, wherein third images of the weather in the third range are provided on the third portion in response to the external weather data without the onboard weather data, wherein second images of the weather in the second range are provided on the second portion in response to the onboard weather data and the external weather data, wherein the second images are provided by determining if a first weather cell in the second range in the onboard weather data is within a predetermined distance of a second weather cell in the second range in the external weather data, and if so, filling between display representations of the first weather cell and the second weather cell in response to altitude values and reflectivity values of the first weather cell and the second weather cell and if not, providing the representations of the first weather cell and the second weather cell without filling.
