Each number one window is a lamination of glass, plastic, anti-ice heating film, and anti-fog heating film. The external and internal window surfaces are glass. The external surface has a rain protection hydrophobic coating.
The windows have retainer rings, moisture seals, and pressure seals. Sealant holds the rings, seals, and window together as an assembly.
Screws go through the rings to attach the assembly to the airplane structure.
There are temperature sensors for the heating films. The heating film and sensors have electrical terminals. The bus bar connects the electric terminals for heat to the heating film.
The number three window has these terminals:
*
Two sensor

*
Two anti-fog electric.

The number one window has these terminals:
*
Three sensor

*
Three anti-ice electric power

*
Two anti-fog electric.

Training Information Point
There are three hoist points to lift each number three and number one window for removal and installation.
Use proper methods when you clean the windows to prevent damage. On the external surface use an isopropanol and water mixture. On the internal surface use a mild soap and water mixture or an isopropanol and water mixture.
You can put a new hydrophobic coating on the number one windows on the airplane.

*
Latches.

There is an alert switch at the top of the window. It operates with a cam that attaches to the top latch.
The window is a lamination of glass, plastic, and an anti-fog heating film. The external and internal window surfaces are glass. The window has electrical terminals for the heating film and for heat control sensors. The bus bar connects the electric terminals for heat to the heating film. Coiled electrical wire connects the window terminals to terminals on the airplane.
There is a retainer ring, sealant, and frame. Screws go through the ring and lamination, and into the frame to hold them together as an assembly.
The silicone bulb pressure seal between the window frame and fuselage attaches to the fuselage.
Training Information Point
Use proper methods when you clean the windows to prevent damage. Use a mild soap and water mixture or an isopropanol and water mixture.
Do not touch the silicone bulb pressure seal when you have the window open for maintenance activities. This can damage the seal and cause air leaks.
