(1) electronic equipments are located in a compartment below the cabin floor aft or the nose gear. This electronic equipment compartment is accessible on the ground through a door in the lower fuselage. If necessary, the compartment can be reached in flight through a floor panel In the forward part of the passenger cabin. Modification and troubleshooting are simplified through use of easily removable shelf assemblies.
电子设备被安装在客舱地板下前轮舱的后面。电子设备组件可通过机身下方的检修口盖来接近。如果有必要，在飞行中，这些组件可通过客舱前端地板上的面板来接近。维修或排故通过用可更换件的装配很容易完成。
(2) There are 3 electronic equipment racks in the electronic equipment bay. They are rack E1, E2 and rack E3.
