Sorry, but I missed the original posting. I believe that at GPT there is no
V522, only V552. Maybe they charted something wrong and the NOTAM was to
change the error, V522, to the correct airway, V552.

AT CAESA VIA V552 WESTBOUND VICE V522 WESTBOUND.

IF and only IF I was wanting to do a full procedure approach coming from
any other direction then westbound, would a procedure turn be authorized
based on the above FDC? If not, what is this FDC about?
