If RVR is inoperative but landing minimums are prescribed in an IAP, what is a required consideration?

When deciding how to proceed with an approach when the Runway Visual Range (RVR) is inoperative but landing minimums are prescribed in an Instrument Approach Procedure (IAP), converting RVR minimums to ground visibility is critical.

RVR is a measurement that provides pilots with information regarding visibility along the runway, which is essential for safe landing under low visibility conditions. When RVR is inoperative, it becomes necessary to rely on ground visibility as an alternative means of determining whether conditions are safe for landing. This can be crucial for ensuring that the aircraft can safely land in accordance with the required visual references.

By converting the RVR minimums to ground visibility, pilots can understand whether the visibility conditions meet the regulatory requirements for a safe landing. This step ensures that the approach can be conducted safely and within the defined limits set forth in the IAP, maintaining compliance with aviation safety protocols.

Other options such as checking for approach clearance or increasing landing altitude may also be part of the decision-making process, but they don't directly address the issue of assessing the appropriateness of the landing based on visibility, which is the focus when RVR information is not available. Proceeding without visibility confirmation is not advisable as it strays from safety procedures. Thus
