Slightly off topic but it is interesting to note the stark contrast between PANS OPS circling areas and TERPS. For cat C, they are 4.2nm and 1.7nm (from that article) respectively.
Trying to remain within 1.7nm of a runway threshold in a medium jet
and do a stabilised approach from 4-500ft AGL would be very difficult with 30° AOB or less. No wonder Americans don't like doing circling approaches.
