today I was reading a document which is giving a basic explanation of the systems of an engine (Link: https://www.faa.gov/aircraft/air_cert/d ... _famil.doc). And as a component of the fuel system of an aircraft engine fuel drains where listed (page 9-10). However it was said that fuel is drained to "safely dispose of the fuel in the manifolds when the engine is shut down, and, in some engines, to conduct leaked fuel overboard."
But when I made some research on the internet I found this: https://www.youtube.com/watch?v=rNdLttyWenQ
(Title: Airbus A320 Fuel Tank Water Drain Valve Operation)
This confused me as the video says the purpose of those drains where to drain the remaining fuel (and water from condensation of the air in the tanks) from the tanks.
So my question is: Are there multiple reasons to drain fuel from the fuel system or are those all different type of drains? And -> When people talk about draining (NOT DUMPING) fuel what action do they mean?
The EPA can is about 10 oz and empties on the next engine start .
