I am curious as to what you are trying to write? the rules are clearly set down, I have just compared three separate company Part A and they are all, more or less word for word.
Pilot assessment of TDZ RVR, when practical, always overrides the reported RVR or met visibility. Pilot assessment, may not be practical where runways are humped or the RVR limit is high.
The reported RVR/Visibility representative of the initial part of the takeoff run may be replaced by pilot assessment.
The required RVR value MUST be achieved for all of the relevant RVR reporting points except as stated above.
Relevant RVR is defined as follows:
For takeoff; The RVR that reflects that portion of the runway required for the whole of the ground manoeuvre, including rejected takeoff.
For landing; The RVR that reflects the landing distance required down to a speed of 60kt’
You may be mixing Landing RVR and Take Off RVR, the subject is comprehensively covered in low vis and all weather ops.
