Embodiment Construction

[0013] The present invention, Convective Weather Graphical Element Generator, provides a system and method for displaying areas corresponding to convective weather on the weather radar display 102 . Figures 2A-2K is a conceptual diagram of a unique graphical element generated by various embodiments of the Convective Weather Graphical Element Generator 200 . This unique graphical element is superimposed on the weather information presented on the weather radar display 102 such that the unique graphical element indicates the location of relatively severe convective weather. Thus, portions of both the rendered graphical element and the rendered weather albedo information for the corresponding area are simultaneously visible on the display.

[0014] Various embodiments use one or more unique graphical elements superimposed on the weather information presented on the weather radar display 102 . This unique graphical element is easily recognizable by the flight attendant of the ai...

Abstract

A system and a method of displaying convective weather on a weather radar display. A convective weather graphic element generator system generates graphic elements associated with severe convective weather for presentation on a display on an aircraft. An exemplary system employs a weather radar and a processing system. The processing system determines a value associated with the detected convective weather based on the received weather radar returns detected by the weather radar, compares the value associated with the detected convective weather with a threshold, and generates a graphic element for a region of airspace when the value associated with the detected convective weather exceeds the threshold. The display is configured to concurrently present the weather reflectivity information generated by the weather radar and the graphic element associated with the convective weather, wherein portions of both the presented graphic element and the presented weather reflectivity information of the corresponding area are concurrently visible on the display.

Description

Background technique [0001] State-of-the-art commercial airborne weather radar systems typically provide the display of weather reflectivity, ground reflectivity, and optionally turbulence. The displayed information is determined from radar returns (radar signal reflections of incident radar signals emitted from the aircraft's weather radar system). [0002] Weather reflectivity is essentially a measure of the "percentage" of the reflected radar signal that is returned to the radar receiver on the aircraft. Weather reflectance information provides an approximate indication of rainfall rates when radar signals are incident on the weather in the vicinity of the aircraft. Weather albedo information is typically displayed graphically on the radar system's display as green, yellow, and / or red areas, where the green, yellow, and red colors correspond to increasing albedo levels. For example, a flight attendant of an installation aircraft may understand that the area shown as the g...
