The Nigerian Airspace Management Agency (NAMA) has successfully installed new Aeronautical Fixed Telecommunication Network, AFTN systems in twenty-six (26) airports across the country. This project, which was the focus of a recent sensitization workshop in Lagos, marks a major step forward in modernizing Nigeria’s aeronautical communication infrastructure.
What is AFTN?
The AFTN is a worldwide system of fixed aeronautical circuits used for the exchange of messages and digital data between fixed aeronautical stations, such as air traffic control centers, airlines, and meteorological offices. It is a critical component of air navigation, transmitting vital information including distress messages, flight plans, meteorological data, and flight regularity messages. The AFTN system
is the backbone of global aeronautical communication, providing a standardized and reliable platform for essential operational correspondence.
Modernizing the AFTN Network
According to NAMA’s Director of Air Traffic Services, John Tayo the new AFTN systems, while operating on the familiar X.25 protocol, utilize more robust global satellite facilities. This technological upgrade provides improved reliability, wider coverage, and enhanced message transmission efficiency compared to older systems. A key benefit of this new AFTN network is its ability to function as a dependable alternative to the Air Traffic Service Message Handling System (AMHS), ensuring continuity of operations in the event of any disruption to the primary system.
Benefits and Importance of the New AFTN
The installation of these new AFTN systems is expected to bring multiple benefits to Nigeria’s aviation sector.
Enhanced Safety of Air Navigation: The AFTN ensures the timely and accurate dissemination of flight safety messages, meteorological information, and urgent notices. This direct support for safe aircraft operations is crucial in reducing communication delays and is a cornerstone of NAMA’s safety mandate.
Improved Operational Efficiency: By facilitating quicker communication between air traffic control units, flight information centers, and meteorological services, the new systems will significantly improve the overall efficiency of air traffic management.
Global Interoperability: With its standardized protocols, the AFTN ensures seamless communication between Nigeria and other nations within the ICAO network, strengthening the country’s integration into the global aviation community. This standardized AFTN system allows for the smooth exchange of critical data for international flights.
Reliable Backup to AMHS: The AFTN remains a robust fallback option, guaranteeing operational continuity in case of any disruption to the AMHS. This redundancy is a crucial safety and security feature of the communication infrastructure.
National Coverage Expansion: With AFTN installations now in 26 airports, Nigeria possesses an extensive and resilient communication network to support aviation growth nationwide.
This widespread coverage ensures that both major and smaller airports are well-connected to the AFTN network.
Tayo concluded by emphasizing that the modernization of the AFTN systems is a clear demonstration of NAMA’s commitment to safety, efficiency, and technological advancement.
He urged all technical and operational staff to utilize the newly installed AFTN systems effectively to ensure optimal performance and maintain Nigeria’s position as a leader in African aviation.

In developed countries, the Aeronautical Fixed Telecommunication Network (AFTN) is still operational but is being gradually replaced by Air Traffic Services Message Handling System (AMHS) and the System Wide Information Management (SWIM) environment. While the AFTN is a foundational network for exchanging critical flight information, its outdated technology and limited capabilities make it difficult to meet the demands of growing aviation. Developed nations are migrating to AMHS for enhanced functionality, security, and the ability to handle larger data, paving the way for integration into future SWIM-based digital ecosystems.
Nigerian Airports should consider upgrading to AMHS. They are far too behind in terms of technology.
I worked in an airport where the AFTN was always malfunctioning. It’s time most of these things received attention.
