Another one - why do QLINK insist on making CTAF calls on CENTRE. They seem to be the only ones who insist on doing this - I cannot see any benefit to it other than clogging up a busy CEN freq.
If it's the call I'm thinking of, it's not a CTAF call. It's given at top of descent when leaving CTA into a class G. Let's everyone in the the general area (who are not on the CTAF frequency) know that you're inbound.
It is an important call as the may be VFR traffic transiting the area that could be a conflict to the inbound aircraft.
