Hi Maxpower. May I add that those are MAXIMUM holding speeds?
Second, not flying heavy iron, I'm able to just use 200 kias as my personal max speed, and that way don't have to bother memorizing speeds/altitudes/countries from the Jepp publications.
Reference range of speeds for the approach segments (pan ops only, I presume. I've never seen this for US/Canada) I don't know of internet locations, but again, the Jepp has them listed.
