@ Uplinker
A running PTU gives "HYD PTU" Memo in green.
Right, 2800 to 3200 psi does not trigger ECAM caution but it is also in the normal operating range for EDPs (FCOM LIM-29).
And yes, it is not normal that the PTU is continuous running during "normal 2 engine ops".
When you make a techlog entry, it would help if you pressure values of both systems with PTU in off.
In addition with PTU in off make some sidestick inputs (diagonal to activate elevator, aileron and spoiler), watch the pressure drop and report deepest values.
Shorten the T/S time...
@ TyroPicard
to keep it simple: every "bark" is a pressure transfer. High demand forces high "barking" frequency.
@ all pilots, who wants more information than just the FCOM
try to get a copy of the AMM (PDF) from a greasemonkey during a visit of your maintenance. (btw: to big to E.Mail it)
