What frequencies correspond to the right and left localizer signals?

The correct answer details the specific frequencies associated with the localizer signals used in precision approaches for Instrument Landing Systems (ILS). For localizers, the frequency is typically 90 Hz. However, this is not relevant for distinguishing between right and left signals.

In standard practice, the localizer provides two signals to guide a pilot to the runway centerline: one for the left side and one for the right. The traditional designation for these frequencies aligns with the ILS configuration where the left localizer signal transmits at 90 Hz and the right localizer signal transmits at 150 Hz. This configuration creates a clear differentiation between the two signals and allows the aircraft's navigation systems to accurately interpret its position relative to the runway centerline.

This understanding behind the correct association of 150 Hz for the right localizer and 90 Hz for the left is crucial for pilots when interpreting the information displayed in their cockpit instruments during an instrument approach. This knowledge is applied in practical situations, helping pilots effectively utilize their navigational aids for successful landings.
