First Claim
Patent Images
1. An aircraft hazard warning system, comprising:
- a processing system configured to cause an electronic display to display an icing condition symbol in response to a presence of an icing condition, the processing system being configured to determine the presence of the icing condition using summation of an icing concentration factor at locations along a first direction, wherein the first direction is along a radial or a flight path and the icing concentration factor is an ice particle concentration per bin, wherein the locations are each associated with a bin associated with an area along the radial, the radial being a second direction of a radar beam, wherein each area is between a maximum radar range and an antenna associated with the radar beam along the radial.

Abstract
A hazard warning system can be utilized in an aircraft. The hazard warning system can include a processing system configured to determine an icing condition. The icing condition can be annunciated and/or displayed. An avionic display can be used to display the icing condition in response to a sum of icing concentration factors along a radial or flight path.

13. A method of providing an icing condition symbol on an electronic aircraft display using an electronic processor, the method comprising:
-
receiving radar reflectivity data; determining an ice concentration factor for each of a plurality of range bins associated with respective locations; and displaying the icing condition symbol in response to a summation of the ice concentration factor at each of the range bins and a threshold, wherein the threshold is determined based upon an engine type or engine operating mode. - View Dependent Claims (14, 15, 16, 17)
