On the A330, you will not get the FCTL DIRECT LAW ECAM on landing gear extension with a dual RA fault, this may be different to other Airbus. Thus I do not believe you need to refer to the direct law procedure.
It is the same as ELEC EMER CONFIG, again you do not refer to the driect law procedure and do not get the ecam on gear extension (Emer Elec shows ALTN LAW: PROT LOST on the status page)
FCOM dual RA does not say refer to direct law procedure, unlike IR DISAGREE, where it specifically refers you to the direct law procedure.
The direct law ecam will show on the status page DIRECT LAW: PROT LOST. and also FCTL PROT on the inop systems You do not get this on the dual RA ECAM.
