Angle of attack sensor with thermal enhancement
An angle of attack sensor includes a vane assembly and a multi-piece faceplate adjacent the vane assembly. The faceplate includes a heated chassis defining a pocket and a mounting plate positioned adjacent the heated chassis and having an opening. The vane assembly has a portion that is positioned in the pocket of the heated chassis and extends through the opening of the mounting plate.
