Regarding White Hearts comment:-
The procedure shoud be changed. FPRSA should telephone the relevant VCR and advise of a late reroute, or of a Company attempting multiple refiles.
FPRSA is an automated system that will process any FPL or CHG message as soon as it is received from IFPS provided that it matches the required route in the database. This makes it difficult for flight plan supervisors to keep track of any late re-files processed in this way and the first that we know about it is when we receive an irate call from the tower asking who had changed the plan!
