Which frequency range is designated for the ILS Glide Slope?

• A. 108.1 - 111.95 MHz
• B. 329.3 - 335 MHz
• C. 75 MHz
• D. 400 - 500 kHz

Answer: (B)

The correct choice for the frequency range designated for the ILS Glide Slope is identified as 329.3 - 335 MHz. The Instrument Landing System (ILS) consists of both the localizer and the glide slope components to assist pilots in landing during low visibility. The glide slope provides vertical guidance to the pilot, and its signal frequency falls within this specified range. The other options represent different frequency bands unrelated to the ILS Glide Slope. The 108.1 - 111.95 MHz range is typically associated with VHF communication frequencies or the localizer component of the ILS, while 75 MHz is the frequency for AM aviation radio. The 400 - 500 kHz range does not align with ILS frequencies either, as it is more adjacent to non-directional beacon (NDB) frequencies. Therefore, recognizing that the glide slope operates within the 329.3 - 335 MHz range helps in understanding the ILS system's functionality and maintaining effective communication and navigation procedures.
