f2K - Do yourself a favour and download your own personal copy of LASORS 2004 free from the CAA website. It'll answer many of your questions (if you can be bothered to look).....

f2k,
There is no "below 140Kt/1800m rule". That is it. It does not exist.
The 140 Kt speed is a division between two limits for VMC. As BEagle says - read the book.
The 1800m visibility requirment applies to IMC holders and is the minimum visibility that they need to take-off and land.
the two are in no way related or connected.

DFC
