The list below provides an overview of the key improvements implemented on 23 May 2019:
- 3rd and 4th sector Tbilisi ACC.
- Implementation of PBN/SBAS procedures in Athens FIR.
- Decommision of FSK and STT Navaids.
- RNAV procedures for Poznan/ EPPO airport.
- Prestwick Lower Airspace (PLAS) 3B.
- DVOR Removal Project/ DVOR Rationalisation Programme.
- FRAU Free Route Airspace Ukraine, Step 1 (Sc 1b) - Phase 2.
Caused by the airspace enhancements implemented during AIRAC 1906 as well as the airspace design improvements put in place since AIRAC 1806 in connection with changing traffic patterns and structure, the additional, potential savings offered during AIRAC cycle 1906 amount to 48 000 NMs flown less compared with the equivalent AIRAC cycle in 2018. This translates into 288 tons of fuel, or 960 tons of CO2, or € 240 000.
Based on the last filed flight plan indicator and as a result of the airspace design improvements put in place since AIRAC 1806 in connection with changing traffic patterns and the airline choices made, the actual losses calculated during the AIRAC cycle 1906 amount to 28 000 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 168 tons of fuel, or 560 tons of CO2, or € 140 000.
While airspace design benefits continue to be implemented the network performance/ flight efficiency improves not to the maximum potential, as it is effected by various crisis and closed areas in adjacent airspace(s). The losses recorded on the last filed flight plan data during AIRAC cycle 1906 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.
