The foremost example (for those flying in Europe at least) is Greece. If you have a set of Jeppesens, take a look at the ATC section of the text manual. Here you will find details, taken from the respective state’s AIP, of the areas in which each state is non-ICAO (PANS-OPS) compliant. Under Greece you will see that the state has declared that its circling procedures are calculated in accordance with TERPS criteria. There is even a helpful diagram detailing the 1.7/2.3nm defined areas. There are other non-compliant states; Israel was at one point and may still be, but my present Jepps. do not cover Israel.
The danger lies in the fact that the relevant airfield approach charts containing circling minima have a JAA/PANS-OPS designation by the minima box and yet no warning that the defined area for circling is not to PANS-OPS standard.
