I understand that in the US controllers anticipate short-term level-offs at 10000' to reduce speed to 250kts (it's mentioned in their AIM). I've not found anything similar mentioned in the UK AIP. Do controllers want us to tell them whenever we intend to carry out a level slow-down at FL100, or do they still expect a minimum ROD of 500fpm?
Thoughts?
