RNAV 1 is one thing. But sometimes it is not enogh with RNAV 1. They also require GNSS. Meaning that IRS/DME/DME is not acceptable even if you have RNAV 1 approval.
The Abu Dhabi procedures are RNAV GNSS: GPS required (still no galileo available)
the Frankfurt procedures:
10-2 is same as Abu Dhabi, GPS required.
transitions: either GPS or FMS required
