Why are you even bothering with circling approaches in this day and age? With straight in approaches published training time can be better utilised elsewhere. The TERPS criteria were/are being progressively changed from 1.7 to 2.7nm from 2013. It's in JEPPS General but the implimentation is not clear...
The Pusan Air China crash photo illustrates why. A straight in approach is not possible in the 18 Runways. Fifteen knots tailwinds are acceptable at Pusan, but in the summer when the sea breeze picks up mid afternoon, the circling approach is needed. It's written to TERPS standards, which is what caught out Air China as they didn't appreciate the different circling radiai between TERPS and PANSOPS. Korea has now moved to PANSOPs - except Pusan. I haven't been there for about 3 years now and I understand there is a RNP(AR) approach for those cleared to do it, now which is far safer.
