The list below provides an overview of the key improvements implemented on 31 January 2019:
- New SIDs Bâle-Mulhouse airport (LFSB).
- ATC Sector Improvement Norway.
- Single CDR category (SCC).
Despite of the airspace enhancements implemented during AIRAC 1902 and the airspace design improvements put in place since AIRAC 1802 the potential route length offered extended compared to AIRAC 1802. This is - beside of changing traffic patterns – probably a consequence of increased number of flights with growing route extensions between origin and destination. The additional, potential route length extension during AIRAC cycle 1902 amounts to 144 120 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 865 tons of fuel, or 2 882 tons of CO2, or € 721 000.
Based on the last filed flight plan indicator and as a result of the airspace design improvements put in place since AIRAC 1802 in connection with changing traffic patterns and the airline choices made, the actual losses calculated during the AIRAC cycle 1902 amount to 219 000 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 1 314 tons of fuel, or 4 380 tons of CO2, or € 1 095 000.
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 1902 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.
