The flight compartment windows give the flight crew an adequate, unobstructed view outside the aircraft under all flight and weather conditions. The windows are structural elements which are able to withstand pressurization forces and impact from a bird strike. The passenger compartment windows give the passengers a view outside the aircraft. The windows are able to withstand pressurization forces and insulate the passengers from the extreme temperatures outside the aircraft. The flight compartment has a pilot windshield and side window, and a copilot windshield and side window. The passenger compartment has 29 window assemblies on the left side and 26 window assemblies on the right side. One window assembly is installed in the emergency exit door, aft passenger door, and aft service door.

The windows are structural elements which are able to withstand pressurization forces and impact from a bird strike. The windows in the flight compartment consist of a pilot windshield and side window and a copilot windshield and side window. The windshields are a fail-safe glass design with an anti-ice heating system powered by the 115V AC electrical system. The side windows are a fail-safe acrylic design. Only the pilot side window has 115V AC anti-ice heating.

FLIGHT COMPARTMENT The face ply is coated on the inside with a conductive, metallic film which gives heating for anti-ice purposes. CONSTRUCTION The flight compartment has two main windshields, one for the pilot and one for the copilot. Each windshield has a 0.120 in (3.05 mm) thermally tempered glass outer face-ply coated on the inside with a conductive, metallic film which supplies heating for anti-ice purposes. A heating element terminal block and three temperature sensors are located near the top of the face ply on the inboard side. Only the forward part of the pilot side window is heated. The heating film extends up to 0.25 in (6.35 mm) from the edge of the Face-ply and covers most of the windshield area except for the extreme forward section. A heating element terminal block is located near the top of the face-ply on the inboard side. Two urethane face-ply interlayers are adjacent to the outer glass face-ply. Three temperature sensors are imbedded in the interlayer immediately next to the glass face-ply. The main structural elements of the windshield are two chemically strengthened glass main-plies. The outer main-ply has a thickness of 0.230 in (5.84 mm) while the inner main-ply has a thickness of 0.180 in (4.57 mm). The two main-plies are separated by a vinyl interlayer. A moulded, silicone rubber gasket is bonded around the edge of the windshield and serves as a weather and pressure seal. The windshield is secured to the airframe by three external, aluminium alloy retainers with bolts. The rear edge of the window is secured by the side window retainer. The copilot side window has two structural stretched acrylic main-plies of 0.38 and 0.31 in (9.65 and 7.87 mm) thickness, laminated together with a vinyl interlayer. There is a polysulfide weather seal and a moulded rubber pressure seal around the edge of the window. The window is retained by aluminium retainers and bolts.

The windows are able to withstand pressurization forces and insulate the passengers from the extreme temperatures outside the aircraft. There are 29 window assemblies installed in the left side and 26 installed in the right side of the passenger compartment. A window assembly is installed in the emergency exit door, aft passenger door and aft service door.
