What is the localizer frequency range?

The localizer frequency range is indeed from 108.1 MHz to 111.95 MHz. This is the range specifically designated for the localizer component of an Instrument Landing System (ILS), which provides lateral guidance to aircraft during the approach phase of landing. The frequencies used for localizers are crucial as they ensure that pilots can precisely navigate to the runway, allowing for safe landings, especially in low visibility conditions.

Understanding the localizer's frequency range is important for any pilot, particularly those flying under instrument flight rules (IFR), as it directly affects communication and navigation during critical phases of flight such as approaches to landing. Frequencies outside this range are not designated for localizer use, which would hinder the ability to receive accurate guidance and could potentially lead to dangerous situations if attempted.
