Implementing Free Routes – AVINOR

Home » Use Cases » S1 » Implementing Free Routes – AVINOR

AVINOR asked us to confirm their readiness to implement FRA (Free Route Airspace) in Norway in compliance with requirements defined with NEFAB (North European Functional Airspace Block) and NEFRA (North European Free Route Airspace Programme).

Replicating different traffic mixes

Together, we decided to test the airspace design and operational procedures under all possible combinations of traffic mix (FRA/fixed). We therefore validated 3 different levels of traffic mix, looking carefully at safety, airspace design and operational acceptability.

Inter-team cooperation

In collaboration with 14 rated controllers and six AVINOR Operational Experts, we conducted real‑time simulations addressing 11 measured sectors in three ACCs at our dedicated centre near Paris in January 2015. In total, we carried out 14 measured exercises, each lasting one hour and fifty minutes.

Combining objective and subjective data

To provide the most complete recommendations, our final validation report drew on subjective ATCO feedback collected via questionnaires and in-depth debriefings, in addition to objective data from the simulation recordings.

“Following successful simulations in 2012 we decided to return to Brétigny for the conduct of these Free Route related simulations in 2014. Again the EUROCONTROL team demonstrated to be very efficient and flexible, delivering a realistic simulation environment with a robust experimental approach leading to a high quality validation report.”
