Multiple Choice

The frequency 122.75 corresponds to which set of letters?

The question tests how radio frequencies are mapped to the labeled letter groups on the aviation frequency chart. In the VHF band, each frequency range is associated with a specific set of letters used in training materials to help you quickly identify which service or channel that frequency corresponds to. 122.75 sits in the common general aviation range used for UNICOM/CTAF-style operations. According to the standard chart used in this training, the letters assigned to that frequency range are C, G, H, I, K, P and Y. That’s why this option is the best answer: it matches the official frequency-to-letter grouping for 122.75. The other groups correspond to different frequency ranges or services, so they don’t fit for this particular frequency.
