ILS (Instrument Landing System)

The Instrument Landing System (ILS) is a precise radio navigation system that helps pilots land aircraft safely, especially in poor visibility. It uses ground-based beams to guide the airplane's position relative to the runway, providing both vertical and horizontal alignment signals. These signals are received by the aircraft’s instruments, which display guidance cues to the pilot. By following the ILS, pilots can keep a safe approach path during landing, ensuring accurate and safe touchdown even in fog, rain, or low clouds. It's a critical technology for safe airport operations in challenging weather conditions.
