Thank you for your response!!!!
Last time I had electricity as topic and the Captain said when I deploy the RAT via the hydraulic panel, the RAT only generates hydraulic pressure and when the RAT will be deployed by the EMER ELEC PWR panel the RAT only generates electricity, but I did not found if it is true or not. In the FCOM is under controls and indicator (hydraulic) written refer to controls and indicator (electricity) and in my mind there is no difference. If I understand correctly, the RAT generates hydraulic pressure and this pressure drives the blue system and the emergency generator in all cases.
Best regards
