Hi Maxpower,
The speeds you mention are
TERPS and this is used only in USA or its 'teritories' ie Guam...etc
The ICAO speeds are based on
PANS OPS . This is from ICAO Doc 8168.
On the approach chart bottom left border you will notice annotations as to whether the approach requires Terps, Pans Ops, Pans Ops 3 or Pans Ops 4.
Pans Ops 3 is just a change of Holding Speeds above 14000' from Pans ops.
Pans Ops 4 is that the acceleration segmet on MAP has been deleted or rather not applicable.
In short, the Holding speeds for Pans Ops for Cat D a/c are:
<6000' - 210k, 6000' to 14000' - 220k, >14000' - 240k
MAP speeds Cat D : Intermediate 185k and Final 265k
Both Terps and Pans ops have diffrent circling calculation for the minima. Terps is based on an ostacle height of 300' whereas Pans ops 394'. So they have diffrent minima and safe radius.
Web sites I'm not sure of but all this info is in the Jepp ref manual.
Hope this helps
