There is disclosed an ice protection system for an aerodynamic structure (for example an aircraft wing) 1100, the ice protection system comprising: a plurality of independently controllable heater elements 1108, 1110, 1112 arranged on the structure: and a control system, operable: to detect an underperformance of at least one underperforming heater element 1114; and to control the supply of power to at least one further heater element 1120 in dependence on a stored relationship or algorithm relating said at least one further heater element to said at least one underperforming heater element. Also disclosed is a heater array wherein the array is arranged substantially diagonal in relation to the leading edge of the structure 1100. Further disclosed is a heater array wherein the array is arranged in a matrix divided both substantially in line with and perpendicular in relation to the leading edge of the structure 1100. Still further disclosed is a system for switching the heating elements on and off to produce a traveling wave for transferring ice across the surface. |
