Airbus 319/320 PTU Mechanics
Am I right in assuming that the PTU operates by using a hydraulic motor in one system to operate a hydraulic pump in the other system?
I'm familiar with how the FCOM defines the PTU, but I have always thought that the description is pretty poor at actually explaining the mechanics behind the thing. The only description I have been able to find is in Aircraft General Knowledge, and it's a pretty basic one.
Thanks
