System for and method of displaying levels of turbulence
First Claim
1. A method of displaying areas of turbulent weather, comprising:
- processing data representative of weather conditions;
displaying the weather conditions on a display;
detecting turbulence;
providing at least one first graphical element upon the display, wherein the first graphical element has a first size and a first location representing a size and a location of the turbulence at a first level, the first level being below a threshold; and
providing at least one second graphical element upon the display, wherein the second graphical element has a second size and second location representing a size and a location of the turbulence at a second level, the second level being above the threshold, providing the at least one second graphical element comprising determining an initial size of the second graphical element based on a geographic area of the turbulence, determining whether to adjust the initial size of the second graphical element based on a minimum display size, and determining the second size of the second graphical element based on the minimum display size;
wherein determining the second size based on the minimum display size comprises;
determining whether the initial size of the second graphical element based on the geographic area of the turbulence at the second level is less than the minimum display size; and
setting the second size to the minimum display size in response to determining the initial size is less than the minimum display size; and
wherein the second size is determined based on an inflation factor, wherein the inflation factor is a function of a peak turbulence within a given radius, a filtered peak turbulence within a given radius, a density of turbulence at the second level, or a number of turbulence detections which exceed the threshold within a given radius.

Abstract
A aircraft hazard warning system or method can be utilized to determine a location of turbulence, hail or other hazard for an aircraft. A processor can process weather radar data representative of weather conditions. An avionic display can display graphical elements representing the weather conditions in response to the processor. The display can provide at least one first graphical element representing a size and a location of the turbulence at a first level. The display can provide at least one second graphical element representing a size and a location of the turbulence at a second level. The size of the second graphical element can have a minimal displayable size and/or can be determined using an inflation factor.
