The implementation of Performance-Based Navigation (PBN) is presently one of the global aviation community's highest priorities. PBN is a global set of the so called "area navigation" standards, defined by the International Civil Aviation Orga- nization (ICAO), based on performance aircra requirements for different phas- es of flight. From ICAO Doc-9849 (see Additional Resources): 2.1.1 – PBN navigation specifications define the accuracy, integrity, availabil- ity, continuity and functionality needed to support a particular airspace concept. Functional requirements include: dis- playing position relative to desired track; display of distance, bearing and time to the active waypoint; database require- ments; and appropriate failure indica- tions. Such a process involves a major s h i f t f rom c onve nt ion a l g rou nd- based navigation and procedures to satellite-based navigation and an area navigation concept. European GNSS (E-GNSS), mainly EGNOS and, in the coming years, Galileo as well, togeth- er with GPS (already operational for years), plays a pivotal role in enabling t he highest per forma nce PBN pro- cedures (i.e., APV-I a nd LPV-20 0). Indeed, this innovative concept leads to the development of more accurate and shorter routes, as well as very effi- cient take-off and landing approach- es. As a consequence, it produces the following immediate advantages: (i) optimization of fuel consumption, (ii) attenuation of airport and airspace congestion, (iii) reduction of aircra emissions, and (iv) flexibility on air- space design. Furthermore, benefits for ATC are also expected in terms of safety enhancement, efficiency of air- space usage, and traffic predictability. BLUEGNSS is a project developed in the framework of the Horizon 2020 (H2020) program involving four ANSPs of different European countries (Italy, Cyprus, Greece, and Malta) plus one industrial partner, IDS (Ingegneria Dei Sistemi). The project objective is to harmonize the implementation of PBN approach operations among the BLUE-MED FAB States. This article provides an overview of the phases required to reach this goal and focuses on GNSS performance assessment as recommended by ICAO.
