Subject to the approval of the Authority, and provided the requirements in paragraphs (A) to (E) below have been satisfied, an operator may reduce the take-off minima to 125 m RVR (Category A, B and C aeroplanes) or 150 m RVR (Category D aeroplanes) when:
(A) Low visibility procedures are in force;
(B) High intensity runway centreline lights spaced 15 m or less and high intensity edge lights spaced 60 m or less are in operation;
(C) Flight crew members have satisfactorily completed training in a flight simulator;
(D) A 90 m visual segment is available from the cockpit at the start of the take-off run; and
OPS 1.430
(E) The required RVR value has been achieved for all of the relevant RVR reporting points.
(ii) Subject to the approval of the Authority, an operator of an aeroplane using an approved lateral guidance sys- tem for take-off may reduce the take-off minima to an RVR less than 125 m (Category A, B and C aeroplanes) or 150 m (Category D aeroplanes) but not lower than 75 m provided runway protection and facilities equiva- lent to Category III landing operations are available.
If your calculated accelerate/stop will not get you into that portion of the runway,then the RVR is not required as it is not deemed relevant.
