There is no TCX ruling on visual approaches at CFU.
However as 7e7 says it is up to the guy flying the thing as to what HE or SHE wants to do, sorry but thats life. CFU can be a dangerous place if not treated with respect.
I have been held up on arrival / departure many times before at many different airfields because the AMM/BY/MON/MYT/ any other airline, has done the full procedure when I was ready to go visual.
