Abstract
A heated bilayer appendage is provided for mounting outboard of an existing non-heated aircraft window. The appendage prevents moisture or frost accumulation on the outboard surface of the appendage so that a clear viewing area is maintained through that portion of the windshield over which the appendage is mounted. The appendage may be provided with an anti-static coating to prevent static charge accumulation on the appendage.
