JAR (1.405): The t/d zone is always controlling. If reported and relevant, the midpoint RVR is also controlling. The min RVR for the mid-point is 125m or the RVR reqd for the t/d zone if less. For aeroplanes equipped with a roll out guidance system, the min RVR for mid-point is 75m, or 125m if not so equiped.
So for CAT 2 you can have minima of 300m/75m for t/d zone and midpoint if auto rollout, or 300m/125m if no roll out guidance.
