What are the minimum requirements for a category B airplane LPV approach when the MALSR is out of service?

For a category B airplane conducting an LPV (Localizer Performance with Vertical guidance) approach when the MALSR (Medium intensity Approach Lighting System with Runway Alignment Indicator Lights) is out of service, the requirement of 4,500 RVR (Runway Visual Range) minimums is established. This specific RVR value is significant because it ensures that pilots have sufficient visibility to safely execute the approach and land the aircraft in adverse conditions, particularly when the approach lighting system, which typically aids in visibility during an approach, is unavailable. Therefore, in this scenario, the 4,500 RVR minimums adequately support safe operations under the specified circumstances.

The other choices, while representing different visibility conditions, do not align with the specific requirements set forth for category B LPV approaches in such situations where the MALSR is not operational.
