excerpt from 777 FCTM:
Raw Data Monitoring Requirements
During localizer-based approaches; LOC, LOC-BC, LDA, SDF, and IGS, applicable raw data must be monitored throughout the approach.
During non-localizer based approaches where the FMC is used for course or path tracking (VOR, TACAN, NDB, RNAV, GPS etc.), monitoring raw data is recommended, if available. Although continuous monitoring of raw data during approaches is not required, ground based navigation aid(s) should be checked for correct navigation no later than final approach.
Airbus:
VOR, VOR/DME, NDB or NDB/DME approach procedures may be performed, in NAV, or NAV and FINAL APP mode, provided AP or FD is used, and : GPS PRIMARY is available.
In this case, the reference navaid may be unserviceable, or the airborne radio equipment may be inoperative, or not installed, provided operational approval is obtained.
Without GPS PRIMARY :
The reference navaid and the corresponding airborne equipment is serviceable, tuned, and monitored during the approach, or the radio navaid coverage supports the RNP value, specified for the approach procedure, and an operational approval is obtained.
For GPS approach, GPS PRIMARY must be available.
Once again, I strongly suggest to check your part A for the operator's approval as a manufacturer recommendation doesn't imply operational approval.
Aristoclis, no matter EU OPS or AIM unless you fly a GPS approach or one of those OR GPS approaches monitoring of a raw data is required as it constitutes primary navigation means.
