To what distance does the Localizer signal provide guidance?

The Localizer signal is a critical component of the Instrument Landing System (ILS), used in precision approaches to guide aircraft during landing. It provides lateral guidance to help pilots align the aircraft with the runway centerline. The maximum range for the Localizer signal is typically 18 nautical miles from the antenna, ensuring that pilots receive accurate directional information as they approach the airport.

This range is established to ensure pilots can have a reliable and consistent signal throughout the descent and approach phases, allowing for safe and precise landing procedures. Understanding the range of the Localizer signal is essential for pilots to confirm they are within the operational limits for utilizing the ILS effectively during approaches.
