interesting moment yesterday on final

If he was IFR its possible ATC did not clear him to go to advisory
frequency soon enough, for whatever reason... maybe he did not have
the airport in sight soon enough. I like to be over on the local
frequency by at least 5 miles out.

If he was IFR, ATC would have probably informed him there was traffic in the
pattern at his destination and might have tried to wait until he had a visual
before allowing him to change frequency.

If he was a big plane with multiple radios (and perhaps pilots), he should
have been monitoring CTAF for many more miles than 3, but he might not have
been talking.

He yielded and did a 360, which implies to me that he might have known the OP
was there and what to expect...
