chrisbl, Airist,
How curious. This is clearly an FAA document, yet in 2 years over there, I never heard anyone say "Over". I know it's positively NOT required in the UK.
When I first went out there, I bought a superb book from ASA called "Say Again Please, Guide to Radio Communications".

Very enjoyable, it takes you through a number of "flights" across different US airspace, with chart extracts. After genning up on it, I can honestly say, the lingo you are taught is exactly how it is used in real life over there.
Suggest the FAA update their documentation...
