Sofema Aviation Services (SAS) www.sassofia.com considers the primary activities within an EASA-compliant Air Navigation Services (ANS) business process.
Introduction
Air Navigation Services (ANS) play a pivotal role in ensuring the safe and efficient movement of aircraft within the airspace. Within an EASA (European Union Aviation Safety Agency) environment, ANS are crucial as they help in managing the complex and busy airspace over Europe. EASA is responsible for civil aviation safety and develops common safety and environmental rules at the European level.
The harmonization of air navigation services under EASA ensures a unified approach to air traffic management across Europe, fostering innovation, cooperation, and continuous improvement in aviation safety and environmental sustainability.
Consider the Various Roles of Air Navigation Services within EASA:
The various roles of Air Navigation Services within EASA are multifaceted, encompassing air traffic control, airspace management, air traffic flow management, safety and regulation, communication, navigation, and surveillance services, environmental considerations, and research and development.
- All these roles work in tandem to ensure the safe, efficient, and sustainable operation of air traffic in the European airspace.
Air Traffic Management (ATM):
Air Traffic Control Services (ATCS) are responsible for preventing collisions between aircraft in the sky and on the ground and expediting and maintaining an orderly flow of air traffic.
- Providing clearances and instructions to pilots.
- Monitoring and managing aircraft movements.
- Providing real-time information on weather conditions and airport status.
- Area Control Centers (ACCs) – Manage aircraft en route in a specific airspace sector.
- Tower Control – Manages aircraft movements on the runways and taxiways of an airport.
- Approach Control – Manages arriving and departing traffic in the vicinity of an airport.
Airspace Management – Ensures the optimal organization of airspace structures to meet the needs of civil and military users.
- Designing airspace structures and organizing the use of airspace.
- Allocating airspace to different users and activities.
- Managing airspace restrictions and temporary segregated areas.
Airspace Classes – Different classes of airspace have varying levels of control, from fully controlled to uncontrolled.
- Flexible Use of Airspace: Allows for the shared use of airspace by civil and military users.
Air Traffic Flow Management (ATFM) – Balances air traffic demand with available capacity in the airspace and at airports.
- Managing air traffic flows to prevent congestion.
- Implementing traffic management initiatives during disruptions.
- Coordinating with airlines, airports, and military authorities for optimal use of airspace.
Central Flow Management Unit (CFMU) – Coordinates ATFM measures at the European level.
- The CFMU was established in 1995 as a EUROCONTROL Directorate in accordance with the International Civil Aviation Organisation (ICAO) Centralised Air Traffic Flow Management (ATFM) Organisation to provide the ATFM Service, on behalf of the participant States, in a specified part of the EUR Region.
- The CFMU comprised the Central Executive Unit and the Flight Data Operations Division with the Integrated Initial Flight Plan processing System. For Airspace Management (ASM) purposes, the CFMU has been also entrusted with the Centralised Airspace Data Function (CADF).
- The Centralised Airspace Data Function is an ASM function entrusted to the CFMU by the European Civil Aviation Conference (ECAC) States for consolidating Conditional Route information contained in the various national Airspace Use Plans (AUPs).
- The CADF compiles these plans into a single coherent list – the European Airspace Use Plan and distributes it on behalf of the States, to the Aircraft Operators.
Note Concerning – CFMU Evolution
In its Single European Sky II legislation, the European Commission created the Network Manager function so as to optimise the European aviation network’s performance.
- The EC nominated EUROCONTROL as Network Manager in July 2011 until the end of the second Reference Period of the Performance Scheme – that is, until 31 December 2019. EUROCONTROL will seek re-designation for the period beyond 2019.
According to the SES II legislation the Network Manager performs 4 main functions:
- Route network design
- Central aeronautical frequency allocation for the European region;
- Coordination of improvement of SSR Code Allocation, and
- Air traffic flow management (ATFM).
In line with the changes to the regulatory framework the central flight plan processing, ATFM and airspace data processing functions of former CFMU are provided by the Network Manager Operations Centre (NMOC).
Flow Management Positions (FMPs): Located at Area Control Centers, they implement ATFM measures locally.
Safety and Regulation – EASA sets safety and regulatory standards for ANS providers to ensure a uniform level of safety in air navigation services.
- Developing and enforcing safety regulations and standards.
- Certifying and overseeing ANS providers.
- Conducting safety assessments and audits.
Safety Management Systems (SMS) – A systematic approach to managing safety, including the necessary organizational structures, accountabilities, policies, and procedures.
Sustainable Aviation Fuels – Encourage the use of cleaner, sustainable fuels to reduce emissions.
Research and Development – EASA and ANS providers engage in R&D to innovate and improve air navigation services.
- Developing new technologies and procedures to enhance safety and efficiency.
- Collaborating with industry stakeholders on research projects.
- SESAR (Single European Sky ATM Research): The technological pillar of the Single European Sky initiative, aiming to modernize and harmonize ATM across Europe.
Communication, Navigation, and Surveillance (CNS) Services – Role: Provides the necessary infrastructure to support air traffic management.
- Ensuring the availability and reliability of communication, navigation, and surveillance systems.
- Managing the spectrum and frequency allocation for aviation.
- Communication Systems: Enable the exchange of information between aircraft and ground stations.
- Navigation Systems: Provide positional information to aircraft.
- Surveillance Systems: Monitor the position of aircraft in the sky and on the ground.
- ANS provide CNS services to facilitate communication between aircraft and air traffic controllers, enable precise navigation, and ensure continuous surveillance of aircraft movements.
Aeronautical Information Services (AIS):
- ANS are responsible for the provision of essential aeronautical information to air operators, including NOTAMs (Notice to Airmen), which are critical for flight planning and safe operations.
Meteorological Services:
- ANS provide accurate and timely meteorological information to air operators, which is crucial for flight planning, fuel efficiency, and safety.
Search and Rescue (SAR):
- ANS coordinate with relevant agencies for search and rescue operations in cases of aircraft distress or accidents.
Safety Oversight:
- Within the EASA framework, ANS are subject to stringent safety oversight to ensure compliance with European and international safety standards.
- ANS are required to implement Safety Management Systems (SMS) to identify and mitigate risks.
Environmental Considerations – EASA is responsible for developing environmental standards and regulations for aviation, including ANS.
- Reducing the environmental impact of aviation, including emissions and noise.
- Promoting sustainable aviation through research and innovation.
- Environmental Impact Assessments: Evaluate the environmental consequences of aviation activities.
- ANS within EASA also have a role in contributing to the reduction of the environmental impact of aviation, including noise and emissions, by optimizing air traffic flows and implementing new technologies and procedures.
Regulatory Compliance:
- ANS operating within the EASA environment must adhere to the regulations and standards set forth by EASA, which are designed to harmonize aviation safety and operational procedures across Europe.
Coordination and Cooperation:
- ANS work in close coordination with various stakeholders, including air operators, airports, and neighboring ANS providers, to ensure seamless and integrated air navigation services.
