There is scope for much embarrassment if you are using Jeppesen charts, as some will have a JAA/PANS OPS designation on the approach chart despite the fact that the defined area for circling is based on TERPS criteria (Greece is the obvious example). Jepps convert TERPS circling minima (visibility and cloud base) to JAA/PANS-OPS standards (including adding 100 feet), but the defined area remains as published by the state.
This means that although the chart in your hand says JAA and not TERPS, you can only circle to 1.7/2.3 miles. Be careful!
