chx230, I don't live in unzud, I don't even know where QT is, but looking at the RNAV F and H, the "circling" minima is actually shown as a "visual circuit" minima. It is not visual circling in the AIP sense of the phrase. The vis minimum for this "circling" is 5km, which means that you can conduct it in VMC; you therefore do not need to keep the runway in sight while doing your wiffodil.
You may get tangled up with your AIP's definition of VMC (Class C? Class D?, Special VFR?, altitude?) WRT vertical distance from cloud, which may or may not upset the applecart, but to my eye it not a true "circling approach".
