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