Oops. My mistake, yes it was advanced RNAV. Some how I confused advanced with enhanced.
I think most RNAV equipped aircraft are actually "Advanced RNAV". Look at these equipment codes:
BASIC RNAV
* /Y LORAN, VOR/DME, or INS with no transponder
* /C LORAN, VOR/DME, or INS, transponder with no Mode C
* /I LORAN, VOR/DME, or INS, transponder with Mode C
ADVANCED RNAV WITH TRANSPONDER AND MODE C
* /E Flight Management System (FMS) with DME/DME and IRU position updating
* /F FMS with DME/DME position updating
* /G Global Navigation Satellite System (GNSS), including GPS or Wide Area Augmentation System (WAAS), with en route and terminal capability.
* /R Required Navigational Performance (RNP). The aircraft meets the RNP type prescribed for the route segment(s), route(s) and/or area concerned.
