It should be noted that the minima for take-off by commercial air transport aeroplanes is 1000 feet cloud ceiling and 1800m RVR
Isn't the RVR take off requirement for commercial ops the same as the RVR detailed on the approach plate at that airfield (or visibility translated into RVR)? In the states it is, if minimums are less than the approach minimums, then take off by commercial operators are banned, even though John Doe in his C152 could quite legally (though probably not wisely) take off.
I took off from Edinburgh with an RVR of 750m, I was following a BA 757....
