Which system assists pilots in landing during low visibility?

The Instrument Landing System (ILS) is a critical system that assists pilots in landing aircraft during low visibility conditions. It provides precise guidance to the pilot during the approach and landing phases of flight, particularly in poor weather where visual references are minimal.

The ILS consists of two main components: the localizer, which provides lateral guidance to align the aircraft with the runway centerline, and the glide slope, which offers vertical guidance to ensure the aircraft descends at the correct angle. This system helps pilots understand their position relative to the optimal flight path and facilitates safe landings even when pilots cannot see the runway due to fog, rain, or other visibility-reducing factors.

Using ILS allows for reduced minimum visibility requirements for landing, enabling airports to continue operations in conditions where visual approaches would not be safe. The integration of ILS in aviation enhances safety and operational efficiency, particularly during adverse weather scenarios.
