(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.
電子設備被安裝在客艙地板下前輪艙的后面。電子設備組件可通過機身下方的檢修口蓋來接近。如果有必要，在飛行中，這些組件可通過客艙前端地板上的面板來接近。維修或排故通過用可更換件的裝配很容易完成。
(2) There are 3 electronic equipment racks in the electronic equipment bay. They are rack E1, E2 and rack E3.
