Nice one Pierre, encourage a newcomer why dont you!
Airspeed,
Such things in the UK are covered in CAP168 and the UK AIP, which to a very large extent encompasses ICAO legislation.
There are also a multitude of ICA Doc's covering the same subject, most of which the FAA adhere to.
Suggest that you look on the CAA and ICAO websites and trawl some information using the quick link facility.
Hope that helps.
