Somewhere in JAR OPS. there is a statement stating that on long runways it may only be the controlling (touchdown) RVR that is required. If the rest of the runway is not used for landing.
Min RVR for rest of runway 150 meters?. Can someone point me to the defining item in JAR OPS.?:confused:

Appendix 1 to JAR Ops 1.430 (Minimum RVR values for take-off) says:

Note 3: The reported RVR/Visibility value representative of the initial part of the take-off run can be replaced by pilot assessment.

Note 4: The required RVR value must be achieved for all of the relevant RVR reporting points with the exception given in Note 3 above.

JAR Ops has this for landing (1.405 f))

(f) The touch-down zone RVR is always
controlling. If reported and relevant, the mid point
and stop end RVR are also controlling. The minimum
RVR value for the mid-point is 125 m or the RVR
required for the touch-down zone if less, and 75 m
for the stop-end. For aeroplanes equipped with a rollout
guidance or control system, the minimum RVR
value for the mid-point is 75 m.
Note. “Relevant”, in this context, means that part of the
runway used during the high speed phase of the landing down
to a speed of approximately 60 knots.
