When to use ICAO holding speeds
 

When does the differentiation take place between ICAO recommended holding speeds and the States recommended holding speeds?

My thought process has always lead me to believe if your flying in US Airspace, you hold using the FAR defined holding speeds, in other words, the State specified speed maxima and minima. That being said, when do the ICAO speeds come into force, when the state does not specifically address the holding speeds?

Sort of confused about this issue, anyone care to shed some light on this subject.

Thanks.

To be pedantic, you should check the State ATC pages in Jepps (or equivalent) to see what the rules are in each country. I think, however, that the US & Canada are the only countries to use TERPS and therefore the FAA speeds.

Thank you for the reply, we do have the state pages in the Jepp, and it makes good sound sense to use those speeds.

Thanks for clarifying this for me.

Then there is the oddity of Japan.
They pattern their ATC procedures after the USA, so use TERPS for approaches, but if I recall correctly, use ICAO holding speeds.
Mix and match, just to make it easy....:E
