2. Description and Operation
A. Cabin Floor Panels
The cabin floor panels are installed between the seat tracks and the floor support structure. Rubber sealing strips are installed between the panels, seat tracks and support structure and screws attach the panels to the structure. The screws are installed with a corrosion preventive paste. The gaps between the panels are filled with sealant. Support struts are installed between the cross beams and support structure to prevent floor distortion.

B. Door Threshold Heater Panels
To increase the cabin temperatures in the emergency exit areas, an electrically heated threshold panel is installed. The panel heater is contained in a metal sheet, shaped to include the contours of the drain ports (to drain away any water that collects when the doors are open) and the panel sides. To reduce downward heat transmission, the bottom of the panel, below the heater element, is filled with insulation. The electrical connector is installed on the bottom of the panel. The installation of these panels is almost the same as the cabin floor panels.
