1. An electrochromic aircraft window assembly comprising:

  • a) an outboard pane assembly; and

    b) a fog preventing electrochromic pane assembly spaced from said outboard pane assembly and defining a chamber therebetween, said fog preventing electrochromic pane assembly comprising;

    i) a first substrate having a first surface including a first conductive coating and a second surface including a second conductive coating;

    ii) a second substrate spaced from said first substrate, said second substrate having a first surface including a third conductive coating, said second surface of said first substrate and said first surface of said second substrate facing each other in spaced-apart relation to define a chamber therebetween;

    iii) an electrochromic medium contained in said chamber and in contact with said second and said third conductive coatings, said electrochromic medium having a luminous transmittance that varies upon application of an electrical potential through said electrochromic medium;

    iv) facilities for applying electrical current to said first conductive coating to heat said first conductive coating, thereby preventing fogging of said window assembly; and

    v) facilities for applying electrical current_to said second and said third conductive coatings to establish said electrical potential through said electrochromic medium and vary said variable luminous transmittance of said electrochromic medium.
