The Civil Air Navigation Services Organisation (CANSO), the International Air Transport Association (IATA), the International Federation of Air Line Pilots' Associations (IFALPA) and the International Federation of Air Traffic Controllers' Associations (IFATCA) have come together to issue this critical joint statement addressing the misuse of the International Aeronautical Emergency Frequency 121.5 MHz. This frequency, reserved exclusively for emergency communications, is vital to ensuring swift responses to distress situations. The inappropriate use of this frequency may pose a serious risk to flight safety, delaying critical assistance to those in need. We urge all aviation stakeholders to carefully consider the importance of safeguarding this frequency and to take immediate steps to ensure it is used strictly for its intended purposes.
