IFiX, That is really interesting stuff; (I was an electronics engineer (not aircraft) before becoming a pilot). A little gem for the examiner on my next line check !
Does memory serve me right that 'PTU' is annunciated in green on ECAM memo when PTU is running? And also that PTU running* during normal 2 engine ops is not normal?
So should we be putting this in the Tech log because a HYD pump may be giving low pressure or low flow? (but not low enough to trigger ECAM caution).
