Can’t seem to find the acronym “CFVBC” anywhere. Does anyone know what this stands for on an approach chart?

It seems to be a waypoint near Indianapolis. Strange name, consonants only.

That’s a computer navigation fix in IND. FMS function. Is that what the OP was asking about though?

Skytrain, where on the approach plate did it feature?
On the mLido plates CFVBC is a waypoint on the extended centreline on the transition towards the IAF, ILS 05R.. FWIW there's a similarly named fix prior to the IAF for 23L, CFBNT.
As to the original question:

It's a waypoint name, it doesn't have to stand for or be an acronym for anything...it's a case of the FMS labelling standard for waypoints requiring 5 letter/numbers..
If there is any logic behind any of the naming at all then given the location(s) maybe "CF " is a hint at "centre(line) fix", given the need for 5 alphanumeric characters total then the rest might simply be alphabet soup though there is often a hint of something with a local significance.
( even this Brit spots that LLARY BBIRD PACRR isn't a random selection... )

CF = Course Fix in some FMS’s.

Apples and oranges. Course to fix is an ARINC leg type. CNF is only used to provide an anchor point for the FMS on a ground-based IAP such as an ILS or VOR approach.

Yes indeed. A CNF is not accepted by ICAO.
