The VOR is "off the air"...which happens to be the transition/via IAF for the STAR.
Using IRS navigation can you still proceed "drct to" via FMS and conduct the STAR via RNAV? (nav accuracy-high/positive)
If "so", then can all RNAV equip'd a/c fly RNAV arrivals/dep. without the assoc. navaids being available (with a high and positive nav. accuracy)
