Your mention of energy management of RAT is rather vague and appears like a general lament. If you could explain the precise concern will be better. I do believe in knowing details of the systems. But at least if you know what is being achieved by the ECAM procedure that is good enough. Normal and abnormal procedures are presented in much the same way as a car's user manual and if you don not have deeper understanding can leave you feeling uncertain despite completing the full procedure. May be that's what you meant.
