Thank You, Bookworm for clarification. You are perfectly right, as I excluded the nonexistance of an instrument approach in my post. What I ment, is that you approached the airport as an IFR flight, so the visual approach can as well just complete an ifr flight (not only the approach) by visual means.
The "runway in sight" thing for continuation of a visual approach in my post above, is an operator requirement to fill up the vacuum left by PANS ATM in the chapter: "that the meteorological conditions are such that with reasonable assurance a visual approach and landing can be completed"
