When are autopilot coupled ILS approaches particularly recommended?

Autopilot coupled ILS (Instrument Landing System) approaches are particularly recommended when visibility is less than 5000 RVR (Runway Visual Range). This recommendation is based on the need for precision and reliability in low visibility conditions, where manual flying may become more challenging due to reduced visual references.

In such scenarios, the autopilot can help maintain the aircraft’s proper flight profile, as ILS approaches provide lateral and vertical guidance to the pilots. This allows for a more stable descent and can enhance safety by reducing the workload on the flight crew at critical phases of flight. By utilizing the autopilot in these situations, pilots can focus on monitoring instruments and making necessary adjustments, which is crucial for ensuring a safe landing when visibility is compromised.

The other options imply conditions where enhanced manual control or visual cues are available, but they do not emphasize the necessity for the autopilot's precision in low visibility, which is why option B is the best choice.
