First Claim
Patent Images
1. A redundant ice management system for an aircraft member, comprising:
- a primary ice management sub-system for providing thermal ice management to an area of the aircraft member; and
a secondary ice management sub-system for providing back-up thermal ice management to the aircraft member in the event of a failure by the primary ice management sub-system, wherein the secondary ice management sub-system manages a majority of the area managed by the primary ice management sub-system.

Abstract
A redundant ice management system and method to de-ice and anti-ice an aircraft member (150) is provided. The system comprising a primary ice management sub-system (154) for providing thermal ice management to the aircraft member and a secondary ice management sub-system (172) for providing back-up thermal ice management to the aircraft member (150) in the event of a failure by the primary ice management sub-system (154). The system provides primary and secondary de-ice and anti-ice capabilities to the aircraft member (150) before and during airborne operation.

18. A method for managing the formation of ice on an area of an aircraft member with an ice management system comprising primary and secondary ice management sub-systems, the method comprising:
-
monitoring the aircraft member and atmospheric conditions for ice formation conditions on the aircraft member;
activating the primary ice management system in response to an indication of ice formation on the aircraft member;
monitoring the primary ice management system to determine its operational readiness and efficiency; and
activating the secondary ice management system in response to the monitoring of the primary ice management system if the primary ice management system fails operational readiness and efficiency requirements, wherein the secondary ice management sub-system manages a majority of the area managed by the primary ice management sub-system. - View Dependent Claims (19, 20, 21, 22)
