Sabenaboy, well yes OLBA is not a good example. You are right. Disregard the limitations on the circling sectors, it’s my fault on the selection of the airport.
Assume there are no limits on the circling maneuver.
Main question is if you are legal to fly overhead for a circling assuming you haven’t reached the MAP yet. Asking for visual is another option, but the original question is by staying on the circling procedure. Nevertheless, airport environment is again required to continue.
B2N2, that’s tricky to master a CAT C jet in 4000m but I think it’s the only way to do it legally.
