Which of the following statements about localizer signals is true?

Localizer signals are a critical component of the Instrument Landing System (ILS), specifically designed to provide lateral guidance during an approach to an airport. They help pilots maintain the correct flight path toward the runway centerline by transmitting signals that indicate deviations from the desired course. This ability to provide precise lateral guidance is essential for safe and accurate landings, especially in low visibility conditions.

The other statements do not accurately describe localizer signals. For instance, localizer signals do not deliver altitude information, which is typically provided by different systems such as the Glide Slope component of ILS. Additionally, localizers are not exclusive to VOR (VHF Omnidirectional Radio Range) approaches; they are part of ILS approaches. Furthermore, localizers are effective at various altitudes, not restricted to below 2000 feet, as they can be utilized during the entire approach phase when aligning the aircraft for landing.
