Air Navigation

Aena works in close partnership with ENAIRE on joint projects to improve airport operations and air navigation. These projects focus mainly on improving communications, navigation and surveillance systems, and integrating air traffic control and airport operation systems.

To develop these projects, Aena and ENAIRE  have followed the guidelines and recommendations of the ICAO, the European Commission and EUROCONTROL, among others, and, particularly, the various EU Framework Programmes for Research and Development and the EU programme for the creation of a Single European Sky (SES).

The following projects are of particular strategic importance:

The European programme SESAR

The SESAR Programme is the technological response of the European aeronautical community (users, service providers, airports, industry, regulators, military authorities, pilots, controllers, research centres, etc.) defining the R&D programme to modernise air traffic control in Europe according to the philosophy of a Single European Sky (SES).

Through its participation in these European projects, Aena is at the cutting edge, implementing the most innovative concepts in airport operations and European air traffic control, taking part in activities in different areas:

  • Operations: The exercise to validate new procedures based on collaborative decision-making (A-CDM), in which Aena is heavily involved, was nominated as the best SESAR exercise in 2013.
  • Environment: projects which form part of the European project, which takes into account the new environmental needs and improvements required for the implementation of the Single European Sky.
  • ATM Master Plan: Aena has contributed to updating the European ATM Master Plan, the last edition of which is a main model for the regulations for implementing the Single Sky at the European level.

European Geostationary Navigation Overlay System (EGNOS)

EGNOS (European Geostationary Navigation Overlay System) is the European system for enhancing navigation signals with satellites in the area of the European Civil Aviation Conference countries. It increases signal precision in current global navigation systems, making it easier to guide aircraft and enabling pilots to make precision approaches.

Aena was involved from the start in the development of EGNOS for aviation, alongside the provider of public air navigation services, ENAIRE. Both companies pioneered the introduction of landing procedures based on EGNOS signals for airport operations in Spain.

Automated Air Traffic Control System (SACTA)

The technological development and automation of the air navigation system have led to the creation of several excellent air traffic management systems; one of them is the Automated Air Traffic Control System (SACTA).

This product is intended to integrate the systems of all the Spanish en route and approach control centres so that they can handle consistent data and work in coordination, and to increase their air traffic control capacity. It also aims to create homogeneity on a national scale between the systems of control.

SACTA has been implemented by ENAIRE in all Aena network airport control towers (with the name VICTOR for control towers).
