On 15th April 2002, Air China B767 CFIT during circling at Gimae Busan (Pusan) South Korea. Weather was low cloud, 215/17, reduced vis. ILS rwy 36 with RH circle to rwy 18.

47 K tailwind at 2200 ft with assumed tailwind on downwind
Close high terrain north of airfield which was not visible
Circling minima 1100 ft, but crew used 700 ft.
Reduced perspective of the runway from LH seat in right turn
Captain had operated to Gimae 5 previous times, but always straight in approaches.
Air China did not consider this to be a special airport
Crew expected straight in, but there was a runway change due doiwnwind on rwy 36

Note that the circling approach procedure has since been modified with stobe lights for the base turn.

My recommendation would be to study the detail of accidents such as this in preference to spending too much time on an app. A good account can be found at http://flightsafety.org/ap/ap_dec05.pdf
