At 2440 feet and 5km from the airport, you become visual but for some reason (be it you're too high, another aircraft on final or on the runway) you can no longer land straight in and instead elect to circle around and fly a right hand pattern (due to the no circling area).
From 5 km out - slow down, tell the fcker to get out of your way, and continue your approach. If the runway is not clear when you get to XXX' (insert whatever figure you are happy with) fly the full missed approach and have another go!

PS: If you are flying an appr to minima, the only other aircraft likely to be on final appr or on the rwy will be a croppie - they are pros and will quickly get out of your way!
