DSNA is developping a broad network of Performance Based Navigation (PBN) approach procedures, in line with ICAO 37th Assembly resolutions, to enhance, complement and optimize the existing network of conventional procedures. This project, which is performance based, adresses a wide range of airspace users potentially equipped with different navigation technologies (GPS, BaroVNAV, EGNOS, RNP AR). PBN capable users can now fly state of the art and locally designed to the need approaches when an Instrument Landing System (ILS) is not present or while in maintenance / replacement.
PBN approaches support a highest level of safety and airport accessibility than conventional approaches. They can support implementing PBN Category 1 approaches which allows DSNA to build an economically efficient reduced ILS network. This PBN DSNA initiative has been cofinanced by TEN-T / INEA and SESAR JU for live trials.

Contribution to increasing capacity of ATM
Runway capacity is increased with lower minima making possible landings possible with lower visibility levels at airports not already equipped with a precision landing system (ILS). This will support maintenaing the capacity in Paris-CDG airport, when the 8 ILS are successfully replaced in the time frame 2016-2020 and increase the capacity in Nice airport under adverse meteorological conditions.
Contribution to increasing safety of ATM
PBN is internationally recognised as a prime mean to increase approaches safety : more direct path and vertical guidance are significant contributors to safety.
Contribution to reducing ATM costs
DSNA has designed a reduced PBN - ILS Cat I network adressing small/medium airfields. This plan allows DSNA to reduce its ILS infrastructure costs, decommissioning 50 ILS. This project was one of the contributor leading to reduce the terminal navigation charge in France :
- 2014 : 233,23 €
- 2015 : 228,62 €
- 2016 : 226,19 €
Contribution to environment
Thanks to optimal PBN flight procedures trajectories and the flexibility of PBN procedure design, the noise envelopes are limited and the environmental impact of air navigation on noise and CO2 emissions is minimised. PBN approach procedures can support continuous Descent Approaches (CDO).
DSNA was one of the first European ANSP to publish PBN approaches (first PBN in 2004). DSNA has also published the first EGNOS PBN procedure in Europe in 2011 and will publish this year the first PBN Cat I in Paris-CDG. In January 2016, DSNA had 173 PBN runways. France will be compliant with the Pilot Common Project regarding the PBN deployment at Paris-CDG, Paris-Orly and Nice airports.
Potential to be replicated over the ATM network
Any ANSP could design such a PBN strategy, all tools and regulations are available in Europe.
There are several innovative aspects in this PBN project: first time in Europe than PBN is used as the main approaches at PCP airports, first European ILS - PBN parallel approaches deployed at Paris-CDG, first time than PBN supports reducing ILS infrastructure costs. Another innovative point is the integration within the project of new European technologies (EGNOS, Galileo in the future).
As a European leader in PBN implementation, DSNA helds an open to industry and foreign bodies PBN forum (quaterly meetings. DSNA teams have shared experience, lessons learned and given support to other European and African (ASECNA) ANSPs.
Contribution to change management
This project is one example of ATM changes introduced within the DSNA operational field, and allowed to demonstrate to our operational experts the benefits of new technologies when the deployment supports additional benefits and the transition is appropriately managed.
Promoting SES and SESAR beyond the Union boundary
This project is also replicable outside Europe, and EC recognition of this project could be one way to promote Europe know-how toward the transition to PBN.
