What does a long landing distance indicate in reduced visibility conditions?

A long landing distance in reduced visibility conditions typically suggests that pilots may face challenges in accurately judging distances on approach and landing. Reduced visibility can be caused by factors such as fog, heavy rain, or snow, which can obscure visual references that pilots normally rely on to determine their altitude and distance from the runway. Consequently, this lack of visual cues makes it harder to judge the aircraft's height above ground level and its position relative to the runway, leading to longer landing distances as pilots may delay their decision to flare or initiate landing procedures until they have a clearer view.

Recognizing this potential difficulty is critical for pilots during approach and landing phases in poor visibility, as they must adjust their techniques and be prepared to compensate for their inability to visually gauge distances accurately. By understanding this aspect, pilots can take necessary precautions and enhance safety when landing under such challenging conditions.
