Apparently there is some kind of list of "eligible airports" for a STAR. These
NOTAMs have been showing up lately for TTA, which is near Raleigh-Durham's class
C. ARGAL5 and BRADE5 are arrivals for RDU. DUAT plain-language translation:

Sanford NC (Sanford-Lee County Rgnl) [TTA]: January NOTAM #13 issued by UAR
ARGAL five arrival (ARGAL. ARGAL5) add TTA as an ELIGIBLE airport effective
from January 30th, 2004 at 11:24 AM EDT (0401301524)

BRADE five arrival (BRADE. BRADE5) add TTA as an ELIGIBLE airport effective

Idle curiosity: I wonder why the oddball effective times.
If you were approaching at 15:22, you could be issued
BRADE5 but not ARGAL5. Two minutes earlier and you can
get neither and two minutes later you can get either.
