What frequency do pilots tune into when overflying an aerodrome?
When clear of controlled airspace and flying in the vicinity of an aerodrome, better situational awareness is gained by monitoring and broadcasting on the CTAF. Pilots of aircraft overflying at altitudes used by arriving and departing traffic should monitor and broadcast on the CTAF by 10 nautical miles (NM). Pilots of non-radio equipped aircraft must not overfly aerodromes where carriage and use of radio is required. These aerodromes are annotated on aeronautical information as CTAF
