European Route Network Improvement Plan (ERNIP) - Monitoring Report - AIRAC 1901

ERNIP Monthly report cover

This ERNIP Monitoring Report informs our partners of major projects implemented on AIRAC 1901 (effective 3 January 2019) which further improves airspace design and enhances flight efficiency.

The list below provides an overview of the key improvements implemented on 3 January 2019.

Island / Norway / UK:

  • Borealis FRA - Step 5 (limited for arrivals/departures Reykjavik transiting via Bodø, Norway or Scottish FIRs).
  • GOLDO Dualisation.

Despite of the airspace enhancements implemented during AIRAC 1901 and the airspace design improvements put in place since AIRAC 1801 the potential route length offered extended compared to AIRAC 1801.

This is - beside of changing traffic patterns – probably a consequence of growing number of medium and long-haul flights thus the average great circle distance having a significant increase. The additional, potential route length extension during AIRAC cycle 1901 amounts to 202 800 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 1 217 tons of fuel, or 4 056 tons of CO2, or € 1 014 000.

Based on the last filed flight plan indicator and as a result of the airspace design improvements put in place since AIRAC 1801 in connection with changing traffic patterns and the airline choices made, the actual losses calculated during the AIRAC cycle 1901 amount to 340 000 NMs flown more compared to the equivalent AIRAC cycle in 2018. This translates into 2 040 tons of fuel, or 6 800 tons of CO2, or € 1 700 000.

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 1901 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
