Following their successful implementation in other parts of the country, a 'listening out squawk' covering Glasgow Airport is to be implemented, the UK Civil Aviation Authority (CAA) confirmed today.
The squawk will become permanent on 2 April 2015 and will be the twelfth 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 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 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.
