History

[edit]

In 1958, under the Act of 26 December 1958, the National Airports Executive was created as a corporation of public law of an autonomous nature, attached to the Air Ministry, which, as a consequence of the Act of 26 December 1958, on the Juridical Regime for Autonomous State Entities, became the Autonomous National Airport Authority (OAAN).

As a consequence of the Air Navigation Act, the OAAN was created, attached to the Air Ministry and dependent on the Subsecretariat for Civil aviation. In 1963 the Subsecretariat for Civil aviation was created within the Air Ministry (still a military authority), to which the OAAN was attached.

Spain signed an agreement with Eurocontrol as an associate state in 1972. The Autonomous National Airport Authority, dependent upon the Air Ministry, signed a convention with Eurocontrol in consideration for the use of the Air Navigation Facilities Network.

In 1977, the creation of the Ministry for Transport and Communications entailed the integration of the Subsecretariat for Civil Aviation into the national civil service.

In 1982 the disappearance of the Subsecretariat for Civil Aviation gave place to the creation of the General Directorate for Civil Aviation (DGAC), which took on the legislative and regulatory powers, as well as those of air navigation. OAAN became part of the Ministry for Transport, Tourism and Communications).

Creation of the public entity Aeropuertos Españoles y Navegación Aérea (AENA)

[edit]

Under the Royal Decree 905/1991, of 14 June, the statute of the public entity AENA (acronym: Spanish Airports and Air Navigation) was approved, and this came into force on 19 June 1991, the day following its publication in the Official Spanish Gazette (BOE). The directives for action by the new entity were set by the Government through the then Ministry for Transport, Tourism and Communications, today the Ministry for Public Works, and competences for management of the network of Spanish airports, air navigation facilities and support networks and control over air traffic were entrusted to it.

On 29 June 1990, in application of Art. 82 of the Act 4/1990, of 29 June 1990, the public entity Aeropuertos Españoles y Navegación Aérea (AENA), attached to the Ministry for Transport, Tourism and Communications, was created.

On 2 November 1991 it began to provide airport services and, one years later, on 2 November 1992, AENA started to provide services related to air navigation.

SACTA put into service at the Air Control Centres

[edit]

Development having got under way in 1984, the operational system SACTA (Automated Air Traffic Control System), is owned by ENAIRE and was developed by Indra[1]. SACTA was put into service at the Control Centre of Palma de Mallorca in the year 1990. In 1991, it came into service at the Air Traffic Control Centre of Madrid and, in 1992, at the Air Traffic Control Centre of Seville as well. At the Air Traffic Control Centres of Barcelona and Canary Islands, it was installed in 1994.

History

Origins and Early Development (1950s–1990s)

The origins of ENAIRE trace back to the mid-20th century, when began centralizing its aviation infrastructure under state control. In 1958, the Patronato Nacional de Aeropuertos was established through the Airports Law, serving as a key precursor to modern management by shifting focus from aerodromes to commercial airports capable of handling and boosting . This entity marked the initial steps toward professionalizing airport operations, facilitating public investment in facilities and safety enhancements during the late Franco era. Following Francisco Franco's death in 1975, Spain's spurred rapid and expansion, driving significant growth in and necessitating expanded airspace management. Passenger traffic at Spanish airports surged in the late and , supported by the country's integration into global markets and the rise of flights, which increased the demand for coordinated air traffic services beyond military oversight. This period saw early efforts to modernize control systems, laying the groundwork for a unified national approach to amid rising flight volumes. On June 19, 1991, the public entity Aeropuertos Españoles y Navegación Aérea (AENA) was formally constituted by royal decree, integrating airport management with responsibilities under a single state-owned body. AENA began providing services on November 2, 1991, responding to the European Union's liberalization and aiming to streamline operations across Spain's growing network of facilities. This formation represented a pivotal consolidation, separating civilian from prior fragmented structures and enabling more efficient oversight of en-route and terminal airspace. Throughout the , AENA implemented the SACTA (Sistema Automatizado de Control de Tráfico Aéreo) system to automate at control centers, enhancing safety and capacity. Development of SACTA began in the mid-1980s, with initial operational deployment in 1990 at the control center, followed by progressive rollout to other facilities in the early . By integrating data and conflict detection, SACTA supported Spain's boom, managing increased trans-European flights while maintaining procedural efficiency in a modernizing .

European Integration and Expansion (1990s–2000s)

In 1997, became a full member of , the European Organisation for the Safety of Air Navigation, enabling coordinated management of across and aligning Spanish with broader continental frameworks for improved safety and efficiency. This integration facilitated the harmonization of procedures and data exchange, supporting the growing demands of trans-European flights while maintaining national sovereignty over . Throughout the , ENAIRE pursued significant expansion to accommodate rising air traffic volumes and enhance operational capacity. In 2001, the new Seville Air Traffic Control Centre entered service, providing advanced facilities for managing southern mainland airspace and contributing to more fluid regional operations. Between 2001 and 2005, similar developments included the commissioning of upgraded control centers in and , which bolstered oversight of insular and oceanic routes, including the busy and corridors. A key advancement in this period was the launch of the first European-level processing system. In 2000, ENAIRE introduced the Integrated Initial Processing Validation system (IFPUV) in collaboration with , standardizing flight plan validation across participating states to reduce errors and streamline pre-flight approvals. Concurrently, the expansion of Communications, Navigation, and Surveillance (CNS) infrastructure progressed, highlighted by the 1999 bilateral agreement with the for the EGNOS satellite-based augmentation system and the 2001 establishment of the European Satellite Services Provider (ESSP), led by Spanish navigation authorities, to deliver reliable positioning services continent-wide. ENAIRE also engaged in early discussions for functional airspace blocks (FABs) with during the 2000s, laying the groundwork for the Southwest FAB (SW FAB). These talks, initiated amid the European Commission's initiative in 2004, aimed to transcend national boundaries by aligning airspace management based on operational needs rather than geography, fostering cross-border collaboration to optimize routes and reduce delays.

Restructuring and Renaming (2010s)

In 2011, the Spanish government initiated a major restructuring of the national aviation entity to separate management from services. On February 25, 2011, the approved the creation of the state-owned company Aena Aeropuertos, S.A., which assumed responsibility for the operation and commercialization of s, while the original public entity retained oversight of and aeronautical information. This separation aimed to enhance efficiency and allow for partial of activities, with Aena Aeropuertos, S.A., commencing operations on June 7, 2011, via Ministerial Order FOM/1525/2011. The public entity, focused on , continued as a under the Ministry of Public Works. The restructuring culminated in further changes in 2014, when the public entity was renamed ENAIRE, standing for Entidad Pública Empresarial de Navegación Aérea y Información Aeronáutica, under Law 18/2014 of . This renaming, enacted through Royal Legislative Decree 8/2014 of July 4, formalized ENAIRE's exclusive role in services, management, and aeronautical information, distinct from the airport operator. Concurrently, Aena Aeropuertos, S.A., was rebranded as AENA S.A. on , 2014, solidifying the corporate split and enabling AENA S.A. to pursue international expansion and private investment while ENAIRE remained fully public. Throughout the 2010s, ENAIRE adapted to regulatory shifts, including the liberalization of aerodrome control services introduced by Law 9/2010 of April 14, which opened competition for tower services at certain airports while designating ENAIRE as the default provider for en-route and approach services. To advance technological interoperability, ENAIRE entered the iTEC collaboration in 2014, partnering with Germany's DFS, the UK's NATS, ' LVNL, and systems integrator to develop shared platforms aligned with European SESAR initiatives. This agreement facilitated joint R&D for next-generation systems, enhancing cross-border efficiency without merging operations. Leadership transitions underscored these reforms, with Ángel Luis Arias Serrano appointed as ENAIRE's on May 29, 2015, bringing expertise from his prior role as of . These appointments reinforced ENAIRE's focus on operational resilience and in the post-restructuring era.

Modern Initiatives (2020s)

In the early , ENAIRE launched its Strategic Plan 2021–2025, known as Flight Plan 2025, which serves as a comprehensive roadmap for , enhancing safety, and improving operational efficiency across Spain's services. This plan was developed taking into account the , during which ENAIRE managed a significant reduction in air traffic volumes before supporting recovery efforts. It emphasizes organizational flexibility, productivity gains, and the integration of advanced technologies such as free route airspace implementation through the HISPAFRA project, scheduled to extend through December 2025. As part of its forward-looking strategy, ENAIRE began evolving Flight Plan 2025 into Flight Plan 2030 in 2025, with a stronger focus on to align with global aviation goals for reduced environmental impact. A significant milestone in ENAIRE's efforts occurred in January 2025, when the Spanish Government authorized the creation of Enaire Global Services (EGS), a new state-owned subsidiary dedicated to exporting air navigation consultancy and operational expertise abroad. EGS aims to capitalize on ENAIRE's established capabilities to secure international contracts, addressing the sector's ongoing transformation driven by technological and regulatory changes, and forms a core component of Flight Plan 2025. ENAIRE has positioned itself as a leader in green during the 2020s, reinforcing its Green Sky Environmental Sustainability Plan in 2024 and 2025 to promote reduced emissions through optimized design, adoption in facilities, and efficient vehicle upgrades under the Eco-ENAIRE initiative. These efforts contribute to broader sustainable development in , with ENAIRE's training programs gaining international recognition from the (ICAO). In 2025, ENAIRE launched the 6th edition of its Professional Master's in Services Management, offered in collaboration with ICAO's TRAINAIR Plus program to foster leadership in sustainable . ENAIRE's collaborative initiatives in the include ongoing participation in the Southwest Functional Block (SW FAB) with Portugal's NAV , which advanced surveillance capabilities through ADS-B deployment in 2024 to enhance cross-border efficiency. Additionally, in December 2024, ENAIRE's Director General, Enrique Maurer, was appointed to chair EUROCONTROL's Board for the 2025–2026 period, underscoring ENAIRE's influence in European air traffic coordination. Subsidiaries like Ineco and CRIDA support these efforts through specialized in digital and sustainable technologies.
