The latest version of the CAA’s ‘Listening Squawks’ card has been released with current codes and frequencies.
Listening squawk codes are allocated to most large airports and aerodromes to enable air traffic controllers to alert pilots if they look likely to infringe airspace.
Pilots set the code into their aircraft’s transponder and listen on the airport frequency when in the vicinity of that airport. The controller will then alert them if required.
The new card depicts all 23 codes and radio frequencies in a quick-reference visual format. The CAA advises GA pilots use the card as part of their pre-flight planning routine this summer.
A large format posteris also being made available for use by flight training facilities and flying clubs. The card and poster also show Lower Airspace Radar Service (LARS) units. Download here
