Changes to listening squawks

listening squawks

Many of the current listening squawks will change this Thursday, 14 September, and five more have been added, making a total of 21 around the UK.

A listening squawk enables an air traffic controller to alert a pilot if their aircraft looks likely to infringe controlled airspace. The pilot needs to turn on the aircraft’s transponder and select the listening squawk, using ALT (Mode C) if available. Tune in to the allotted frequency without transmitting, and listen out for your callsign or position.

Air traffic control will know that you are listening out and can call you on the frequency if you are getting too close to controlled airspace. Once you leave the area, or change radio frequency, change the transponder code back to 7000.
