The drain and vent system consists of lines collecting and carrying waste fluids and vapor overboard from the engine and nacelle accessories. Drains are provided to carry fluids from any point where lines and accessories may leak and where fluids may accumulate in a cavity. Fluid from forward and aft sumps, oil-fuel heat exchanger, VBV, and VSV are discharged overboard through drains. In addition, some drain lines serve as vents to carry air and vapor from the engine and accessory cavities.

A. 放泄系统由管路组成，管路收集来自发动机和短舱的废液和水汽，并把它们排向机外。放泄管出现在可能泄漏的管路、附件的任何点上，也可能出现在油液会聚集于某一个腔的地方。来自于前后腔、滑油-燃油换热器、可调放气活门、可调静子叶片的油液也会通过这些放泄管排到外面。有些放泄管还有通风口的作用，它们会把发动机和附件内的空气和水气带到外面。
