Alidaunia trials PBN along southern Italian route
Alidaunia, always keen to implement new technologies, draws operational benefits in the development of PBN routes, ensuring significant advantages in terms of 24 hour operation and in marginal weather conditions.
To implement PBN, Alidaunia is working with the European Global Navigation Satellite Systems Agency.

Alidaunia, a company providing transport services to and from the Tremiti Islands in the Adriatic Sea, as well as emergency medical service missions that support the relevant local community, has used an AW169 helicopter to test performance based navigation technology supplied by ENAV in collaboration with Leonardo. The companies used the Foggia to Tremiti S. Domino Island route in the Apulia region of southern Italy.

PBN procedures, carried out through advanced satellite navigation and aircraft avionics, significantly contribute to air space optimisation, delivering greater flight operation safety thanks to greater navigation, approach and landing precision and accuracy, a key enabler particularly in certain weather conditions. PBN is combined or replaces the more traditional land-based radio navigation systems.

Moreover, PBN procedures ensure a reduction in polluting emissions and noise through dedicated routes and lower fuel consumption. Passenger transport, emergency medical service and rescue, disaster relief operations, surveillance and fire-fighting are among the main applications that can benefit from this technology in all-weather conditions, day and night. Its adoption and implementation significantly enhance flight safety, environment protection, public service flexibility, responsiveness and effectiveness, and air transport efficiency.

The Foggia to Tremiti S. Domino Island route is the first in a network that is being developed locally to support the helicopter operations of the regional heliport network called Rete Eliportuale Puglia. The successfully validated procedures, using a latest generation Leonardo AW169 helicopter, are the result of a collaboration between Alidaunia and the European Global Navigation Satellite Systems Agency (EGSA) in the framework of the PHAR project (PBN for HEMS in the Apulia region).

The procedures will be characterised by high precision linked to the use of special navigation requirements that will allow safe flight even at low altitude, reducing polluting emissions and noise, integrating helicopter and aircraft operations with an optimised use of airspace.

ENAV has been at the forefront of PBN procedures design for both fixed- and rotary-wing aircraft for years. Leonardo, a leading company in the field of aerospace, defence and security producing latest generation helicopters equipped with state-of-the-art avionics and advanced satellite navigation capabilities, such as the AW169, is one of the few manufacturers in the world today able to codify and produce PBN navigation databases.

Alidaunia, at the forefront in the development and implementation of new technologies, draws important operational benefits in the development of PBN routes, ensuring significant advantages in terms of 24 hour operation and in marginal weather conditions.

The demonstration activity in Apulia is the first one carried out since the signing of the letter of intent between ENAV and Leonardo, which was announced in October 2020, aimed at offering helicopter operators in Italy and abroad products and services in the advanced instrument navigation field, whilst also contributing to modernise the relevant infrastructures. These capabilities, provided through the collaboration between two major players in the aeronautical field, now make possible the development and use of procedures in accordance with the modern requirements of the Performance Based Navigation to support the different phases of flights, increasing safety and operational effectiveness.
