- The designated CTAF published for that aerodrome (Correct answer)
- 130.0 MHz (military common)
- Any available clear VHF frequency
Correct answer: The designated CTAF published for that aerodrome
RPA operators must broadcast on the designated CTAF published in the ERSA or on the aeronautical chart for that specific aerodrome.
