What must happen if the RVR drops below minimums inside the FAF?

If the Runway Visual Range (RVR) drops below minimums inside the Final Approach Fix (FAF), it is essential to prioritize safety and compliance with aviation regulations. The correct response in this scenario involves a decision-making process that must adhere to established guidelines for continuing approaches under visual conditions.

Continuing until visibility improves is permissible under specific regulations and only if the pilot remains confident that conditions will stabilize and allow for a safe landing should visibility increase. Pilots must assess the situation continuously and ensure they can maintain a safe approach based on available information, including runway visibility and weather conditions. The key here is that if the RVR is below minimums but improvement is expected, continuation might be deemed acceptable.

In contrast, initiating a go-around or landing as soon as possible would not be the appropriate response unless the pilot could no longer maintain a safe approach. If visibility is critically low, descending without concern lacks a safety measure and disregards the necessary precautions needed to ensure successful navigation and operation under challenging visibility conditions.
