Flew into LFMN / NCE yesterday. Noted the 'Saleya' Circling procedure with prescribed tracks for 22L/R utilizes a 20 DME arc from the AZR VOR. It expects you to be at MAX 200KIAS and 4000' upon completion of the arc. This is around Min Clean on the 737-800.
Again another destination that I have been to recently (EGCN / DSA) utilizes a 12D arc to established onto the LOC for the ILS. No speed guidance issued on the plate. So practice standard speeds when applicable or permitted.
220KIAS at the IAF and 180KIAS on base. So I'm flying between these speeds. Always seems to work.
