Final answer:
The runway requirements when operating at RVR 5/5/5 include adequate lighting, clear runway surface, and reliance on navigation aids. Pilots and aircraft must meet specific requirements for low visibility operations.
Step-by-step explanation:
When operating at RVR 5/5/5, the runway requirements refer to the minimum visibility needed for the safe operation of aircraft. RVR stands for Runway Visual Range and is a measure of the horizontal distance a pilot can see down the runway. RVR 5/5/5 means that the runway visibility is 5,000 feet in both directions.
In order to operate at RVR 5/5/5, the runway must have adequate lighting, including runway edge lights, threshold lights, centerline lights, and touchdown zone lights. Additionally, the runway surface should be clear of any obstacles or debris to ensure safe landing and takeoff.
During low visibility conditions, aircraft may also need to rely on instrument landing systems (ILS) or other navigation aids to guide them along the runway. Pilots must be trained and certified to operate under these conditions, and aircraft must meet specific requirements and have appropriate equipment for low visibility operations.
