The UK Civil Aviation Authority (CAA) has released a new version of it’s popular ‘listening squawks’ flight card in time for the summer general aviation flying season. 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 simply dial-in the code into their transponder and listen-in 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. All GA pilots are advised to use the card as part of their pre-flight planning routine this summer. A large format poster is 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.

The CAA has begun distributing copies of the card and poster to the GA community, but pilots can download their own copies from

Hard copy versions will also be available on the CAA stand at major GA events such as AeroExpo this summer.
