What are the requirements to descend below the MDA/DH?

The requirement to descend below the Minimum Descent Altitude (MDA) or Decision Height (DH) primarily hinges on the availability of visual references. This essentially means that a pilot must be able to see and identify visual cues, such as the runway, approach lights, or other significant landmarks that indicate a safe approach and landing can be made.

Visual references are crucial because they allow the pilot to determine their position concerning the intended runway and to ensure that they are aligned properly for a safe landing. If these visual references are not apparent, the pilot must remain at or above the MDA/DH to maintain safety during the approach.

In contrast, while clear visibility and a stable approach configuration are important for safe landings, they do not directly address the specific requirement of having visible references to descend below MDA/DH. Similarly, pilot experience, although valuable, does not fulfill the critical requirement of visibility for this maneuver. The requirement to be at a specific altitude is also less relevant, as the focus is on the visual cues necessary for confirming a safe landing rather than maintaining a predetermined altitude.
