The list below provides an overview of the key improvements implemented on 28 February 2019:
- Direct Route Airspace Greece H24 - Phase 3b.
- Free Route Airspace Warsaw FIR, Phase 4.
- Prestwick Lower Airspace (PLAS) 5a.
- Swanwick Airspace Improvement Programme (SAIP) - Airspace Deployment 2.
- Lightning Project (EGD323 re-design to meet military requirements).
Caused by the airspace enhancements implemented during AIRAC 1903 as well as the airspace design improvements put in place since AIRAC 1803 in connection with changing traffic patterns and structure, the additional, potential savings offered during AIRAC cycle 1903 amount to 26 000 NMs flown less compared with the equivalent AIRAC cycle in 2018. This translates into 153 tons of fuel, or 510 tons of CO2, or € 128 000.
Based on the last filed flight plan indicator and as a result of the airspace design improvements put in place since AIRAC 1803 in connection with changing traffic patterns and the airline choices made, the actual losses calculated during the AIRAC cycle 1903 amount to 24 000 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 144 tons of fuel, or 480 tons of CO2, or € 120 000.
As a result of Free Route Airspace developments flight efficiency improved, but not to the maximum potential, as still effected by the various crisis and closed areas in adjacent airspace(s). Additionally, network performance was strongly impacted by capacity, applied regulations, weather and industrial actions, while airspace design benefits continued to be implemented.
The losses recorded on the last filed flight plan data during AIRAC cycle 1903 compared to the equivalent AIRAC cycle in 2018 are mainly because of different flight planning/ airline choices, traffic composition and/or scenarios applied due to capacity problems in the network as well as special events.
