1. An aircraft hazard warning system, comprising:
- a processing system configured to detect a high altitude ice crystal (HAIC) or high altitude ice crystal cloud (HAIC2) condition and cause a warning of the HAIC or HAIC2 condition to be displayed, wherein the HAIC or HAIC2 warning is provided on a weather radar display such that weather regions in a same location as the HAIC or HAIC2 warning are viewable on the weather radar display, the HAIC or HAIC2 condition being detected using weather radar returns associated with a high altitude region, the weather radar returns being processed to detect the HAIC or HAIC2 condition, wherein the weather regions are provided as a solid green region for precipitation levels below a first level, a solid yellow region for precipitation levels above the first level below a second level, and a solid red region for precipitation levels above a third level, wherein the HAIC or HAIC2 warning is displayed as yellow dots or cross sectional lines on a weather region depicted as a solid green region, wherein the processing system detects a high altitude associated threat (HAAT) condition and wherein the weather radar display provides visual indicia according to the following table;

Abstract
A hazard warning system can be utilized in an aircraft. The hazard warning system can include a processing system for determining a high altitude ice crystal (HAIC) condition and causing a warning of the HAIC condition to be displayed. An avionic display can be used to display the warning of the HAIC condition.

11. A method of providing a high altitude associated threat (HAAT) warning and one of at least a high altitude ice crystal (HAIC) or high altitude ice crystal cloud (HAIC2) warning on an aircraft using an electronic processor, the method comprising:
-
receiving radar reflectivity data and determining at least one of a HAIC or HAIC2 condition exists; displaying the at least one of the HAIC or HAIC2 warning of the HAIC or HAIC2 condition over weather regions on a weather radar display, wherein the weather regions on the weather radar display are viewable when the at least one of the HAIC or HAIC2 warning is displayed; determining the HAAT condition exists; and displaying the HAAT warning over weather regions on a weather radar display, wherein the weather regions on the weather radar display are viewable when HAAT warning is displayed, and wherein the HAIC or HAIC2 warning is not viewable at locations where the HAAT warning is displayed, wherein the HAAT warning and HAIC or HAIC warnings are displayed according to the following table; - View Dependent Claims (12, 13, 14, 15, 16)

17. An aircraft weather radar system, comprising:
-
a radar antenna for receiving radar returns; and means for determining a high altitude associated threat (HAAT) condition and at least one of a high altitude ice crystal (HAIC) or high altitude ice crystal cloud (HAIC2) condition and providing a warning of the HAAT condition and at least one of the HAIC or HAIC2 condition at least partially in response to the radar returns, wherein the means for determining performs one or more of the following to detect the presence; a dual frequency process; a dual polarization process; an ice crystal shape determination process;
ora non-coherent integration and turbulence detection process; and means for displaying the at least one of the HAIC or HAIC2 warning over weather images, the at least one of the HAIC or HAIC2 warning being visual indicia, wherein the means for displaying provides the HAAT warning and the HAIC or HAIC2 warning according to the following table; - View Dependent Claims (18, 19, 20)
