Hi,
http://www.smartcockpit.com/docs/a350-9 ... pilots.pdf
In the link above (ATA 29, page 29.3), it is said that "The Hydraulic System Monitoring Unit (HSMU) monitors EDP clutch".
I never heard about EDP clutch in other airplanes.
a-Is this clutch a new device in the EDP?
b-What's the function of the clutch in this EDP (engine driven pump)?
c-Besides A350, are there other aircraft that their EDPs (engine driven pump) are fitted with a clutch?
