What is the Localizer frequency range?

The Localizer frequency range is indeed correctly identified as spanning from 108.10 to 111.95 MHz. This range is used by the Instrument Landing System (ILS) for precision approaches, providing lateral guidance to aircraft on final approach to runways. The Localizer signals are critical for helping pilots align with the runway centerline, especially in low visibility conditions. Understanding the specific frequency range for Localizer operations is essential for both air traffic control and pilot operations, as it ensures that navigational and communication equipment is tuned correctly for accurate navigation and safe landing procedures. The other options provided do not represent the correct frequency span used for Localizer systems.
