1. A sensor, comprising:
an airfoil body defining a sensor axis and having a leading edge, a trailing edge, an ice accretion feature and a tip surface extending from the ice accretion feature to the trailing edge;
a heater element extending axially through the airfoil body between the leading edge and the trailing edge of the airfoil body; and
a temperature probe extending axially through the airfoil body between the heater element and the trailing edge of the airfoil body, wherein the heater element is axially overlapped by the ice accretion feature to accrete ice chordwise forward of the tip surface;
wherein the ice accretion feature extends from the leading edge of the airfoil body to an ice accretion feature terminus that is located chordwise between the heater element and the temperature probe.
