B777 Hydraulic Fluid transfer
Hello ello,
This may be a completely stupid question, however, i cant seem to find the answer. In the CBT and tech manual it says to pressurise the RHS hydraulic system first, and depressurise it last to prevent unwanted fluid transfer. I've been looking at the system diagrams, in both cbt and tech manual, and can not see any physical connection between the systems. How can fluid transfer?, if fluid can transfer what is the purpose of designing it that way?
Thanks a lot.
