ENR 1.5 4.23.9
just like everything else about Queenstown it has its own special case. It’s not actually a circling maneuver, it’s discontinuing the approach and continuing with visual reference ..anyhow, it doesn’t state you must have visual contact with the runway on a circling maneuver, just the runway environment. That’s loose enough to keep lawyers in pay for years if you ever had to argue it in court. I’ve flown the figure of eight a few times in my life and if you stretch your neck you can usually see some part of frankton most of the time
