Thanks - that confirms a significant difference between ICAO and TERPS. Under ICAO, the max circling speeds are separately defined. Under TERPS they relate to Approach category, which for most 737/AB drivers NB puts you in Cat D for all circling on TERPS, eg Greece (I believe still??), Israel, and North Am.
Incidentally, the FAA doc may be out of date as it does not mention 1.23 Vs1g - or is this not recognised in FAA land?
