Narrative:

We had another aircraft that; after his flight plan was filed; needed to depart non-RNAV. Again; although we knew what the non-RNAV routing should have been; we were unable to remove the pdr with the RNAV routing. After amendment (revision 3); his route showed +..ood..tebee..haydo..sby.+ .+ood.OOD198..SBY018.sby.V1.ccv... At that point; his equipment suffix had been changed to /a; but still the pdr appeared. The full readout of his ICAO flight plan information after the 3rd amendment showed as follows: ...flr I flight south wak M eqp dov srv C ala kiad oth...rna 1 rnd 1 rne 2. Because we were unable to remove the RNAV pdr; tower had to advise the departure sector; who then had to advise the center sector. Minor problem; and since the non-RNAV underlays the RNAV route; a lack of this communication occurring would not be problematic. Still; the fix should be able to occur while the aircraft is on the ground; not be reliant on local and departure remembering to coordinate with the next sectors. I do not know who can answer the basic question: how do I change an ICAO flight plan from RNAV to non-RNAV? I suspect that the 'rna 1 rnd 1 rne 2' has to be removed somehow; since that has to be there regardless of what's under eqp if you want to get the RNAV routing; but no one knows how to do it. My recommendation is exactly the same: a manual. Some better-informed support personnel would be nice too; but I'm happy to learn on my own since that seems unlikely.

Title: PHL Controller described a confused routing event when attempting to change an ICAO flight plan from a RNAV departure to a conventional procedure; the reporter indicating more training is needed for clarity.
