Final answer:
When visibility is low or the RVR is reduced, several considerations need to be taken for landing, including weather conditions, aircraft and pilot capabilities, and airport infrastructure.
Step-by-step explanation:
When the visibility is less than 3/4 statute miles or the RVR (Runway Visual Range) is 4,000 or less, there are several considerations that need to be taken for landing. One of the most important considerations is the weather conditions, which include factors such as clouds, wind, and rain. Poor weather conditions can affect the visibility and make landing more challenging.
Another consideration is the capabilities of the aircraft and the pilot. The pilot needs to ensure that they have the necessary training and skills to land in low visibility conditions. The aircraft should also be equipped with instruments and technology that can assist in landing in low visibility.
Furthermore, the airport itself needs to have proper lighting and navigation aids to assist the pilot during the landing process. This includes runway lighting, approach lighting systems, and precision instrument approaches.
