Instrument Landing System (ILS)

The Instrument Landing System (ILS) is a precise radio navigation system used to guide aircraft safely during landing, especially in low visibility conditions. It employs two radio signals: one provides lateral guidance (left-right alignment), and the other offers vertical guidance (approach angle). These signals are received by antennas on the ground and processed by the aircraft’s instruments, helping pilots align their approach accurately with the runway. ILS enhances safety and precision during landings, ensuring aircraft follow the correct path even in fog, rain, or darkness.
