Windows - Component LocationA. Cockpit
(1) Fixed Windows
(a) The cockpit window-frames are riveted to the fuselage. The windshields and fixed side windows are installed directly into the frame structure. Installation is made from the external area of the cockpit.
(b) Each windshield assembly is made of a number of layers of toughened glass. Thereare two types of fixed side windows. One made of number of layers of stretched acrylic laminate known as acrylic windows and other one made of layers of toughened glass . Each assembly is set in a moulded silicon-rubber seal.
(c) The windshields and fixed side windows are chemically strengthened and are resistant to hail and bird-strike damage. Electrical heating elements give clear vision in all conditions.
(2) Sliding Windows
(a) The sliding side-windows are attached to support tracks before they are installed in the frame structure. Installation of the sliding side-window assembly is made in the cockpit.
(b) The sliding side-windows are of two types. One made of number of layers of stretched acrylic laminate known as acrylic windows and other one made of layers of toughened glass . Each assembly is set in a moulded silicon-rubber laminate. Each assembly is set in a moulded silicon-rubber seal.
(c) The windows are chemically strengthened and are resistant to hail and bird-strike damage. Electrical heating elements give clear vision in all conditions.
(d) The sliding side windows have a mechanism to open, close and to lock them. The crew can use them as emergency exits.
B. Cabin Windows
(1) Cabin windows are installed on both sides of the fuselage between the frames. The locations extend the length of the cabin.
(2) The window frames are made from forgings and are riveted to the fuselage skin.
(3) The window assembly can be of two types. One consists of two separate panes of stretched acrylic laminate known as acrylic windows and other one consists of window panes made of toughened glass. Each assembly is set in a silicon rubber seal. A retainer ring, eye-bolts and nuts holds the assembly in the frame.
(4) A hole is included in the lower center of the inner pane. The hole lets the pressure between the two-pane assembly stay the same as the pressure in the cabin.
(5) A cabin window is installed in the top center of each emergency exit, left and right.
C. Cabin Dummy Windows
(1) Cabin dummy windows are made of aluminum installed in place of the cabin windows when necessary. They are installed in locations where furnishings or equipment block them (galleys, lavatories, stowages, etc.).
(2) When you replace a cabin window assembly with a dummy window, use the same retainer ring, eye-bolts and nuts.
D. Passenger/Crew Door Windows
(1) Each passenger/crew door has an observation window. The window is installed off-center because of the door opening, closing and lock mechanism.
(2) The window frames are made from forgings and are riveted to the door outer skin.
(3) Each window assembly is made of two separate panes of stretched acrylic and set in a silicon rubber seal. A retainer ring, bolts and nuts hold the assembly in the frame.
NOTE: The forward passenger/crew door windows inner pane is made with a 40 degree prism. The prism gives the cabin crew direct downward vision to the outside of the aircraft when the door is closed.
(4) A hole is included in the lower center of the inner pane. The hole lets the pressure between the two-pane assembly stay the same as the pressure in the cabin.
