A ‘listening out squawk’ covering Farnborough Airport is to be made permanent, the UK Civil Aviation Authority (CAA) confirmed today. The code was originally created as a short term measure to assist Farnborough LARS air traffic controllers during the London 2012 Olympics. It proved so successful, however, that it remained in place on a trial basis after the Games finished. The squawk will become permanent on 14 November 2013 and will become the tenth such code in operation in the UK.
Listening out squawks, officially known as Frequency Monitoring Codes, have played a vital role in reducing infringements of controlled airspace (CAS) by enabling air traffic controllers to alert pilots if their aircraft looks likely to infringe. Any aircraft fitted with a Mode A/C or Mode S SSR transponder can use these codes. By entering the relevant four-digit SSR code into the transponder and listening to the published radio frequency, a pilot signifies to air traffic control that he/she is actively monitoring radio transmissions on that frequency.
The Farnborough Frequency Monitoring code is 4572 and the radio frequency to monitor for Farnborough LARS (West) is 125.250MHz. This squawk is to be used by pilots who intend to operate in the area covered by LARS West, and do not require a service. Pilots operating within 8nms of Farnborough or 3nms of OCK VOR (see chart extract)
have been requested to call Farnborough as they do now.

‘Listening out codes’ are listed in UK AIP ENR 1.6.2 — SSR OPERATING PROCEDURES. A number of aerodromes publish procedures associated with their respective codes within their individual AD2 2.22 - FLIGHT PROCEDURES. Publication in both is recommended by the CAA when approving the establishment of codes.
A handy leaflet
containing all the codes can be downloaded from the Airspace & Safety Initiative (ASI) website. An updated leaflet featuring the Farnborough code will be given away in the November issue of Flyer
