Bristol to get ‘listening out’ squawk

The UK Civil Aviation Authority (CAA) has confirmed Bristol Airport will be allocated a ‘listening out’ squawk from May 2015. The ever-popular squawk codes have played an instrumental role in reducing the number of airspace infringements by general aviation aircraft at the UK’s largest airports.

Officially known as Frequency Monitoring Codes, a listening out squawk enables air traffic controllers to alert a pilot to their close proximity to the boundaries of controlled airspace – if their aircraft looks likely to infringe. Any aircraft fitted with a Mode A/C or Mode S transponder can use these codes. By entering the relevant four-digit 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 and their aircraft position is visible on radar.

The Bristol listening out squawk code will be 5077 and will become operational on 28 May 2015 and the radio frequency to monitor will be 125.650MHz. It is recommended that pilots flying anywhere within the vicinity of Bristol Airport use the code.

An Information Notice with more details has been published today by the CAA. An updated leaflet containing the new Bristol code will soon be available from the Airspace & Safety Initiative (ASI) website.

2. ‘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.

3. ASI is a joint CAA, NATS, AOA, GA and MoD effort to investigate and tackle the major safety risks in UK airspace. airspacesafety.com

4. The CAA is the UK’s specialist aviation regulator. Its activities include: making sure that the aviation industry meets the highest technical and operational safety standards; preventing holidaymakers from being stranded abroad or losing money because of tour operator insolvency; planning and regulating all UK airspace; and regulating airports, air traffic services and airlines and providing advice on aviation policy from an economic standpoint.
